A full autoland was not possible.
Time to move on....and don't start another thread to reply to something someone's said here — Lfdder (talk) 11:19, 20 July 2013 (UTC) |

The following discussion has been closed. Please do not modify it. |
While stated with good intention, that is not accurate. No airliner can do a full autoland without a fully functioning and certified CAT III b/c system (or an equally capable MLS system) in operation at a specific runway. And, at SFO, they cannot have planes landing on both 28L & 28R at the same time, if any plane is doing a full autoland. ATC would have to be informed in advance (even if the wx is VMC) so they can ensure that planes on the ground are not too close to the ILS transmitters. Additionally, the plane itself has to be current, which means it has successfully conducted an autoland within the last 30 days, and the logbook has been signed off on that required periodic test. And finally, BOTH pilots must have been trained, tested and certified to conduct a full autoland operation, and that cannot be done until they have had a required amount of time in that plane, which means no "High Minimums" captains or first officers can conduct such an approach. EditorASC (talk) 14:09, 18 July 2013 (UTC)
That was a statement by Apteva (talk) 19:26, 16 July 2013 (UTC), in the "Misc sources (CRM, hand-flying, automation, culture)" section, that was closed. The rules require that I reply in another section that is open. EditorASC (talk) 22:32, 18 July 2013 (UTC)
"The NTSB said that a variety of levels of automation were available, but that zippering in the flights to 28L and 28R was done because the runways are so close together." That does not mean the plane was capable of a full autoland. It wasn't, for reasons stated above. No, there is no rule that says I am required to respond. However, I think it is very important to correct inaccurate information that is posted in Wikipedia, for obvious and logical reasons. EditorASC (talk) 22:37, 18 July 2013 (UTC)

90 second evacuation delay
I would like to propose that the 90 second evacuation delay be included in the lead, as it certainly is a significant fact of the accident. Whether it was a brilliant decision that saved 304 lives or whether it was a decision that contributed to 3 deaths can not be speculated upon. Apteva (talk) 19:41, 19 July 2013 (UTC)
- Which sources state that it was significant? And come to that, which sources state that the delay was due to a 'decision'? AndyTheGrump (talk) 19:51, 19 July 2013 (UTC)
- It is a factual description of the accident. We hit the ground, we waited 90 seconds to evacuate. A flight attendant instructed another to ask the pilot if they should evacuate, and were told no. A flight attendant noticed fire outside the cabin and asked again, and were told to evacuate the plane. That was 90 seconds later. It is just a basic fact. Whether it was important or not will be determined by the NTSB. If I was reading an article about an accident, I would assume that passengers were evacuated immediately upon the aircraft coming to a stop, unless I was alerted to a delay in the beginning of the article. This is not the sort of detail that anyone should have to read down into the article to learn. I was not using the word "significant" to mean "important" but to mean "a long time", as in more than 5 or 10 seconds. Apteva (talk) 20:00, 19 July 2013 (UTC)
- Without a source indicating that this was a key decision in the sequence of events, it seems overdetailed for the lede. VQuakr (talk) 20:15, 19 July 2013 (UTC)
- As our article stands, it isn't that clear at what point the first question from the cabin crew came - the '90 seconds' was from when the plane came to rest. I don't have time to watch the source (the long NTSB briefing) right now - is there a transcript which might clarify this? AndyTheGrump (talk) 20:31, 19 July 2013 (UTC)
- Try this.[2] Apteva (talk) 23:39, 19 July 2013 (UTC)

Apteva's source is a good one. Here are a couple more:
"The pilots are in the front of the airplane," she [Hersman] said. "They really don't have a good sense of what's going on behind them." [3] [4]
That is a highly significant piece of news, since NO evacuation should ever be delayed, even for just a few seconds, when a plane is damaged that badly. That it was delayed and the passengers were actually told to remain in their seats, is solid fact, supported by NTSB Hersman, and should be in the lead as suggested. EditorASC (talk) 05:47, 20 July 2013 (UTC)
- The cockpit told the flight attendants to delay evacuationCheckingfax (talk) 06:29, 20 July 2013 (UTC)
- No, it shouldn't be. Don't make assertions. Wait for the investigation. — Lfdder (talk) 09:27, 20 July 2013 (UTC)
- Just like the fire truck death, we initially put it in the lead, then when it was not certain it was a contributing factor we moved it out, (keeping it in the body), then when it was released that it was the cause of death we put it back into the lead. While we will not likely know for a year if the NTSB thinks that the delay was or was not a mistake, it certainly warrants being in the lead as being totally unexpected and quite unusual. I mean seriously, if you were the only person on a plane that crashed would you sit on the ground for 90 seconds before getting out of there (if you could)? Apteva (talk) 21:50, 20 July 2013 (UTC)
Sensationalism?
Several passengers recalled noticing the plane's unusual proximity to the Bay on final approach,
Those passengers and other eyewitness accounts of aviation accidents are often, pardon my French, crap. They are biased and unreliable.
I once saw a passenger insist that the tail of a plane was broken but that was a normal gap when the rudder turns. The passenger saw the plane at a gate.
Accident investigations usually tabulate unreliable passenger assessments but rely on objective measures, like the altimeter. In reality, when the plane is over water, altitude is very difficult to judge from a passenger side window, particularly if they can't even see the runway.
We have to be cautious because readers with aviation experience will laugh at WP. Let's try to do a good job. Let's axe this sentence in italics. Auchansa (talk) 19:54, 19 July 2013 (UTC)
- Even if they were right? The only time the plane was low, though, was in the final seven seconds before impact, beginning just about the same time that the throttles were advanced. Apteva (talk) 20:37, 19 July 2013 (UTC)
- News reports covered the passengers' reactions. (I'm waiting for the OP to tell us that not only were the passengers wrong, but that the plane didn't actually crash.) ←Baseball Bugs What's up, Doc? carrots→ 21:36, 19 July 2013 (UTC)
- I think his point is that eyewitness testimony can be unreliable. It's not that the passengers are lying; but it's that human perceptions can miss things. WhisperToMe (talk) 22:31, 19 July 2013 (UTC)
- Sure, it can be. Was it, in this case? ←Baseball Bugs What's up, Doc? carrots→ 23:33, 19 July 2013 (UTC)

Inline citations should not occur in the lead?
I thought the MOS specifies that no inline citations should appear in the lead. The lead is to restate/sumarize the gist of the article, and the inline citations go in the body. --Mareklug talk 20:59, 19 July 2013 (UTC)
- That's the standard procedure, yes. I think citations are sometimes included in the summary just to head off complaints about things being uncited. ←Baseball Bugs What's up, Doc? carrots→ 21:37, 19 July 2013 (UTC)
- I have removed the citations from the lead and put them where they belong. --Mareklug talk 23:26, 19 July 2013 (UTC)
- Kudos. ←Baseball Bugs What's up, Doc? carrots→ 23:32, 19 July 2013 (UTC)
- I think if something is controversial it should be cited, but if not, and it occurs elsewhere in the article, then the citation goes outside the lead WhisperToMe (talk) 04:39, 20 July 2013 (UTC)
- To quote the MOS at WP:LEADCITE: "Because the lead will usually repeat information that is in the body, editors should balance the desire to avoid redundant citations in the lead with the desire to aid readers in locating sources for challengeable material. Leads are usually written at a greater level of generality than the body, and information in the lead section of non-controversial subjects is less likely to be challenged and less likely to require a source; there is not, however, an exception to citation requirements specific to leads. The necessity for citations in a lead should be determined on a case-by-case basis by editorial consensus. Complex, current, or controversial subjects may require many citations; others, few or none." VQuakr (talk) 05:39, 20 July 2013 (UTC)

Admin - Please Prevent Edit War re Image Caption for visually impaired
It appears that editor Jehochman is unhappy with some useful edits made by Mareklug and has reverted them. Unfortunately, Jehochman's initial edit was accompanied by needless snarky commentary while his edits both decreased the encyclopedic quality of the article and removed image captioning that assists the visually impaired and is helpful to others.
I would normally just revert Jehochman's latest re-revert but I don't want to set up a situation where "edit war" rules start to get imposed.
If Jehochman wants to argue about style, he can do so, civilly, on the Talk page.
Can some administrator take a look at this series of edits?
If senior admins find I have miscategorized the edits, so be it, I won't take further steps to remove Jehochman's unhelpful edits.
Thanks Ande B. (talk) 19:33, 11 July 2013 (UTC)
- Yeah, fully supportive of reviewing Jehochman's actions and his snarky edit remarks - it just isn't helpful to deal with issues like that. There are without a doubt many contributors who may not be as familiar with wp, and its markup, but acting like that is not constructive, especially because it is probably pretty safe to assume that most wp admins are not necessarily aviation experts, ATCOs or even type rated 777 pilots - thus, skills, expertise and knowledge should complement each other - what's going on here is plain ridiculous and doesn't help quality at all, I have seen knowledgeable contributions reverted by people due to stylistic issues, and plain wrong stuff being added, reviewed and approved just because it matches wp style, is that intended ? Please, think about it - or just lock the article and have 3-5 guys with a background in aviation act as reviewers, while others can take care of stylistic stuff and proper refs. Thank you --Parallelized (talk) 19:54, 11 July 2013 (UTC)
- Thank you for noticing that. You guys are a bunch of really uncollegial editors, and I'm not going to waste time arguing with you at all. Jehochman Talk 20:06, 12 July 2013 (UTC)
- I specifically alerted you to these developments so that you could provide a little insight - unfortunately, you failed at that, big time I may add. Don't get me wrong, improvements are appreciated - but please don't touch contents that you don't understand, I am sure everybody will appreciate your stylistic contributions - to help those people who actually know a thing or two about aviation with using wp.--Parallelized (talk) 21:24, 12 July 2013 (UTC)
- Wikipedia Single Point Editor specifically discourages that exclusivity, IMHO. Checkingfax (talk) 06:59, 21 July 2013 (UTC)
I've also had a problem with one of Jehochman's edits, which ignored discussion, and removed an edit and its cite, with the comment that the edit was uncited. Hopefully we don't have to waste time on these kinds of issues and can focus on improving the article. guanxi (talk) 20:55, 11 July 2013 (UTC)
- Maybe someone could first try to talk to that dude, I mean he seems pretty accomplished over here, and even an admin - obviously not an aviation expert, but there should be an option to get him involved to help people who are not as familiar with wp, instead of having to report him outright? But reverting stuff like that is just crazy, and frankly, pretty discouraging.--Parallelized (talk) 19:12, 12 July 2013 (UTC)
- Comment: I have now had to revert Jehochman's removal of descriptive cutline for the interior shot twice, and both edits of that Wikipedian came with snarky edit summaries. Also, now, that he has removed the reference in the text to oxygen masks being deployed on impact (survivor account), the cutline is the only textual manifestation of this, and of course, the NTSB-supplied picture is reliable source in this case. Ditto for the information about the seats remaining in place. The seats remaining in place is a crucial bit of information not mentioned anywhere else in the text, yet responsible for so few fatalities. Seat strengthening to withstand 16G acceleration is one of the hallmarks of improved survivability of modern passenger aircraft. Also, it is entirely within Wikipedia policy to restate pictorial/graphic information in text, precisely for the consumption of visually impaired, as Ande B. already mentioned, as well as readers employing textual browsing. I would hope Jehochman will not cause a need to revert this unjustified edit one more time. I would also like to ask for less snark in edit summaries. --Mareklug talk 00:35, 12 July 2013 (UTC)
- Maybe find a citation for the seats remaining in place, otherwise this seems like original research. --Malerooster (talk) 00:54, 12 July 2013 (UTC)
- The NTSB-supplied picture is citation enough. After all, this is the cutline to go with it. --Mareklug talk 01:22, 12 July 2013 (UTC)
- This is the essence of WP:OR. I am not seeing this "cutline", not sure what that is, not sure if that would matter, but can you link it? --Malerooster (talk) 01:28, 12 July 2013 (UTC)
- No, it is not original research. Information comes in many modalities. An officially released picture is one of them. https://en.wikipedia.org/wiki/Cutline -- is a description of a photograph. You are looking at it. --Mareklug talk 01:31, 12 July 2013 (UTC)
- I mean all the seats didn't remain in place, but thats besides the point, since a photo is open to interpretation. Just find a RS and be done with this, why is that so hard? --Malerooster (talk) 01:34, 12 July 2013 (UTC)
- Industry experts said the Asiana plane, a Boeing BA +1.31% 777, had a significant advantage over older models: It was equipped with a new generation of seats, the majority of which stayed in place instead of breaking loose from their floor tracks or collapsing, which could have caused many more serious injuries. In 1988, the Federal Aviation Administration began requiring that seats on newly designed, newly certified planes must withstand inertial force equal to 16 times the force of gravity in static testing. Today, that is the world standard. The FAA declined to make a seat specialist available for an interview. http://online.wsj.com/article/SB10001424127887324694904578598041567963334.html Will you revert your removal now? --Mareklug talk 01:42, 12 July 2013 (UTC)

- You do realize that that you are being POINTy, as well as uncooperative. Your Comment: came after I quoted a textual RS you called for. Also, in WP:MOSCAPTION, which you directed me to in your last revert's edit summary, it is stated: Captions for technical images should fully describe all the elements of the image, and the image's significance. --Mareklug talk 02:01, 12 July 2013 (UTC)
- This is NOT a technical image and why not use alt text? Also, I still haven't seen the "cutline" you referred to earlier. I went to the twitter picture and didn't see it, but might have missed it. Also, the photo shows that some of the seats did not remain in place, but again, that would be original research to say that in the text. Still waiting for a RS that covers this, rather than a stand alone photo. --Malerooster (talk) 02:12, 12 July 2013 (UTC)

Chinese passengers
Here in the article states that "Almost half of the flight's passengers were Chinese because of Seoul's status as a major connecting point between China and North America; as of July 2013 Asiana Airlines operates between Seoul and 21 cities in mainland China. There had been a lack of direct flights between many Chinese cities and the United States, and low prices and territorial disputes between Japan and China have caused many Chinese to transit via Seoul."
I removed these. In this case, there is no need to analyze Chinese passengers' tendency and put these disputed reasons in the article, since more than 90 of the flight's Chinese passengers actually departed from Shanghai taking OZ362 (Xinhua News Agency, in Chinese), where there are multiple choices to fly to SFO, including several direct flights and both Japan Airlines' and All Nippon Airways' flights. The Japanese flights take too long, but the duration of OZ362->OZ214 is considerably short, this may play a more important role than the low price or Anti-Japanese sentiment. --Tomchen1989 (talk) 06:34, 20 July 2013 (UTC)
- Tom, one crucial aspect of Wikipedia is WP:V, meaning that verifiability and not truth is the criterion for inclusion. So that has a consequence with point number one.
- 1. "The Japanese flights take too long, but the duration of OZ362->OZ214 is considerably short, this may play a more important role than the low price or Anti-Japanese sentiment. " - Do you have a reliable source saying that the flight length is more important than the price or the anti-Japanese sentiment?
- 2. "where there are multiple choices to fly to SFO, including several direct flights and both Japan Airlines' and All Nippon Airways' flights." - While it is true that there are multiple options out of Shanghai, the WSJ article also mentioned the price factor (as in Seoul connecting flights were fairly inexpensive), and that doesn't account for the other Chinese passengers on the flight who may have originated from smaller Chinese cities.
- WhisperToMe (talk) 15:06, 20 July 2013 (UTC)
- I was fully aware of WP:V but I also found that the WSJ article is from WP:NEWSBLOG which may be acceptable if the author is professional, but should be used with caution. Here I want to cite two news articles in Chinese: China Economic Net's news article, which was republished by Xinhua, Sina and many other websites (Chinese media have legal right and like to simply copy and republish news articles written by other media), compares the price of Asiana Airlines' connecting flight with the price of China Eastern Airlines' non-stop flight like the WSJ blog author, and suggests that the low price is the main factor. But it is very disputed in Chinese forums and microblogs, because by consulting online flight booking websites, in most cases, one may easily find flights cheaper than Asiana Airlines'. {That was what Yangcheng Evening News' journalist did. According to this news article, on Shanghai-based travel agency Ctrip's website, the journalist found an Air China's flight with one stop cheaper than Asiana Airlines'. In this news article, some experts agree that Asiana Airlines' tickets are mostly cheap but not always, "a responsible person of a large flight ticket agency website" claimed that Chinese flights might be more expensive than non-Chinese ones several years ago, but not now; connecting flights may be always cheaper than non-stop flights; Chinese airliners operate both non-stop flights and connecting flights, and people should always compare non-stop flights with non-stop flights, or connecting flights with connecting flights (which is exactly the opposite of what WSJ blog author and the China Economic Net author did). According to the news article, other factors that may make Asiana Airlines more competitive than Chinese or other airlines, include quality of service, airline brand influence, country's visa-free policy, and even psychological factors (Chinese may want to take foreign airlines' flight to have a different experience).} However, I find it not necessary to analyze those complex things and dig it too deep in an article named "Asiana Airlines Flight 214", not "Airlines' marketing strategy towards Chinese passengers", "Aviation market share in China" or something. The current revision of the article is just fine, why insist on adding all those debates in it? --Tomchen1989 (talk) 21:03, 20 July 2013 (UTC)
- We can use a source if a journalist uses, say, the WSJ's argument and directly contradicts it. If a journalist researches the claims and publishes a news article on it, then it's absolutely fair game and should be considered. In regards to using criticism on self-published microblogs and/or Wikipedians consulting flight schedules on their own it may be considered original research to a degree (how does an individual challenge the claims by the WSJ?). I do agree that there should not be too much focus on that aspect, but the reason why I would like to add some of it is because it helps readers understand the significance of the flight, on why so many Chinese were on board. I added similar information to China Airlines Flight 611 (TPE-HKG known as the "Golden Route") and Swissair Flight 111 (UN shuttle, and clientele of diplomats and politicians) as well as Sosoliso Airlines Flight 1145 (Nigerian schoolchildren originating from Port Harcourt used it to fly from Abuja from their boarding school because the roads were too dangerous) WhisperToMe (talk) 00:06, 21 July 2013 (UTC)
- No that's beyond "an individual challenge the claims by the WSJ". That, in my previous post, is a Yangcheng Evening News news article (which is written after interviewing local pros and experts) versus a WSJ blog article (see WP:NEWSBLOG). To make it more clear, I now use braces "{}" to indicate those raised by Yangcheng Evening News in my previous post.
- Now our article says "Seoul Incheon serves as a major connecting point between China and North America", that is good, that's a simple fact, very objective. But if we play that "fair game" like you said, adding a lot of contradictory, subjective points of view, like price, flight length, quality of service, airline brand influence, country's visa-free policy, and even psychological factors (the anti-Japanese sentiment as the WSJ blog says, or the preference of choosing foreign airline to have a different experience as one of the Yangcheng Evening News' interviewees, a Chinese airline's marketing manager said), we need to add lots of these as well as to discuss whether they are main factors or whether they are valid factors, we may be immersed in that "fair game", and I just don't think it's necessary to play any game here. I also found no such game played in the articles China Airlines Flight 611, Swissair Flight 111, Sosoliso Airlines Flight 1145, "Golden Route", "UN shuttle", dangerous roads, they are all simple, objective, non-disputed facts, just like "Incheon is a major connecting point".--Tomchen1989 (talk) 05:27, 21 July 2013 (UTC)
- As I said above " I do agree that there should not be too much focus on that aspect" so if there is a better place for the discussion perhaps it can go in the Seoul Incheon article and that would work. :) - Since many contradictions were published by the Yangcheng Evening News, that makes the issue complicated, and the complexities can be discussed in another article. I don't make a distinction between a "NEWSBLOG" and a regular news article since a "NEWSBLOG" is just a presentation of a newspaper article, as the NEWSBLOG section states.

I do agree that there should not be too much focus on that aspect, but the reason why I would like to add some of it is because it helps readers understand the significance of the flight, on why so many Chinese were on board. I added similar information to China Airlines Flight 611 (TPE-HKG known as the "Golden Route") and Swissair Flight 111 (UN shuttle, and clientele of diplomats and politicians) as well as Sosoliso Airlines Flight 1145 (Nigerian schoolchildren originating from Port Harcourt used it to fly from Abuja from their boarding school because the roads were too dangerous) WhisperToMe (talk) 00:06, 21 July 2013 (UTC)
- I was fully aware of WP:V but I also found that the WSJ article is from WP:NEWSBLOG which may be acceptable if the author is professional, but should be used with caution. Here I want to cite two news articles in Chinese: China Economic Net's news article, which was republished by Xinhua, Sina and many other websites (Chinese media have legal right and like to simply copy and republish news articles written by other media), compares the price of Asiana Airlines' connecting flight with the price of China Eastern Airlines' non-stop flight like the WSJ blog author, and suggests that the low price is the main factor. But it is very disputed in Chinese forums and microblogs, because by consulting online flight booking websites, in most cases, one may easily find flights cheaper than Asiana Airlines'. {That was what Yangcheng Evening News' journalist did. According to this news article, on Shanghai-based travel agency Ctrip's website, the journalist found an Air China's flight with one stop cheaper than Asiana Airlines'. In this news article, some experts agree that Asiana Airlines' tickets are mostly cheap but not always, "a responsible person of a large flight ticket agency website" claimed that Chinese flights might be more expensive than non-Chinese ones several years ago, but not now; connecting flights may be always cheaper than non-stop flights; Chinese airliners operate both non-stop flights and connecting flights, and people should always compare non-stop flights with non-stop flights, or connecting flights with connecting flights (which is exactly the opposite of what WSJ blog author and the China Economic Net author did). According to the news article, other factors that may make Asiana Airlines more competitive than Chinese or other airlines, include quality of service, airline brand influence, country's visa-free policy, and even psychological factors (Chinese may want to take foreign airlines' flight to have a different experience).} However, I find it not necessary to analyze those complex things and dig it too deep in an article named "Asiana Airlines Flight 214", not "Airlines' marketing strategy towards Chinese passengers", "Aviation market share in China" or something. The current revision of the article is just fine, why insist on adding all those debates in it? --Tomchen1989 (talk) 21:03, 20 July 2013 (UTC)
Victims list
Is there any reason why the three victims' names are not mentioned? I am just curious. Many articles I see list the names of the fatalities. Thanks. Joseph A. Spadaro (talk) 20:50, 20 July 2013 (UTC)
- We dont normally list names of victims for aircraft accidents unless they are otherwise notable before the accident, normally indicated by them having a wikipedia article. MilborneOne (talk) 20:55, 20 July 2013 (UTC)
- I assumed that EN Wikipedia might have some kind of privacy policies to protect the teen victims when I found the lack of their names. --Tomchen1989 (talk) 21:14, 20 July 2013 (UTC)
- No, just notability. All three names are publicly available. Apteva (talk) 21:40, 20 July 2013 (UTC)
- Personally both the presence and the lack of the victims' names are OK for me. But if the privacy is not we concern about, then I see no reason to prevent adding victims' names. WP:Notability doesn't apply here, since notability guidelines do not limit content within an article. Also, counter-examples can be found, one of the victims' names appears in Atlantic Southeast Airlines Flight 529; among the Swissair Flight 111#Notable victims, there are also someone whose notability may be questioned, like a daughter of an entrepreneur, two university professors. I think if there are too much victims in an accident, then the names should be reasonably limited in our article. But if the victims are very few, their names can be reasonably mentioned. --Tomchen1989 (talk) 05:52, 21 July 2013 (UTC)
- There's no reason not to list their names and other info. There would not likely be justification for creating separate articles about them, as that's when the notability rule would come into play. ←Baseball Bugs What's up, Doc? carrots→ 17:23, 21 July 2013 (UTC)
- All passengers and most of the crew are victims. The reason not to list the deceased victims is because it clutters the article. What about people who suffered permanent injuries? How about people who commit suicide afterward? What if someone is left in a permanent vegetative state, but did not die? There has to be some consistency: Are you going to list the name of every deceased victim when there are hundreds or thousands? Notability is the criterion we have. If we make another criterion, like 5 or fewer deaths of passengers and crew, then it needs to be applied across other disasters and accidents. 75.208.16.211 (talk) 23:09, 22 July 2013 (UTC)

Cause of death
Saying they died after being run over by the fire truck does not in any way indicate that the fire truck caused the death, as was stated by the coroner. After could mean 75 years after, and have nothing to do with the fire truck incident. After could mean that after being run over by the fire truck they were still alive, but succumbed to injuries due to the crash, and not due to injuries due to being run over. From is a better word than after. From is also better to use for the other death as well. The crash was not an illness that anyone died "of", it was a trauma that someone died "from". Just as a guess, I would think that they died while they were being run over, but "from being run over" is fine. Apteva (talk) 13:49, 21 July 2013 (UTC)
- "From" is correct. "After" is an imprecise colloquialism. ←Baseball Bugs What's up, Doc? carrots→ 17:21, 21 July 2013 (UTC)
- I was under the impression that the girl hit by the truck had sustained injuries that might have proved fatal with or without the collision, and so was deliberately being imprecise. But I went back and reread the article about the firetruck, and the coroner did say she died because she was hit by the truck. So after-> from is fine. Disagree that "died of" is only used in cases of disease, but won't argue the point further. PRRfan (talk) 18:26, 21 July 2013 (UTC)
- If you did argue the point, you would be correct. The distinction between "injury" or "disease" is not important. In English grammar it is quite appropriate to state that someone died of an injury. 75.210.152.163 (talk) 17:33, 22 July 2013 (UTC)

Vandalism of an editor's post on the talk page.
Move on, please. Article talk pages are not for discussion of editor behavior.
|
---|
I removed an insert by another editor, that changed my post on the talk page. It made it looked like I had said the words that he inserted in the middle of my post. It was quite proper for me to remove it, since it was MY post and not his. Wiki rules do not permit any editor to alter the posts of another editor, so I had every right to remove it. Incredibly, anther editor reverted my removal and put back that false, misleading, unethical and downright deceptive altering of my post, by his insertion of HIS words, in my post so as to make it look like it was part of what I had intended to post. In short, you have aided and abetted a vandalism of my post. That cannot be allowed to stand. I will continue to remove words put in the middle of my posts, by other editors, without my permission. If you don't like it, then take it to Admin and try to justify why another editor should be allowed to alter the posts of other editors. I would love to see your argument for allowing that fraudulent state of affairs. EditorASC (talk) 12:59, 24 July 2013 (UTC)
Yeah. 1: Vandalism has a pretty specific meaning involving malintent. Not all unhelpful or erroneous edits are vandalism. 2: It may have been more helpful to just move the comment for the user instead of putting it right back where it was. 3: The comment has now been moved to a more suitable place, so this should be settled now. Happy editing, Pseudonymous Rex (talk) 13:33, 24 July 2013 (UTC)
I do doubt that there was any mistake as to authorship of my remarks. I certainly meant no harm or offense. Please accept my humble apology. I thought EditorASC was doing fine work overall on the article. I am glad to work with him wishing only that he will be more gentle. I think that the easiest fix would have been for EditorASC to paste his sig above above my comments which were indented and signed. The second easiest fix would have been to ask me to relocate my replies. 75.210.75.165 (talk) 15:59, 24 July 2013 (UTC) I think the fairly simple explanation is that EditorASC and I have very different styles for replying that are mutually incompatible. He tends to quote others in his replies. I try to to co-locate my replies with the original statement. Now I am aware to watch out for this. But if I forget, please be gentle. I don't know just how this works, because my response in this thread appears after EditorASC's list of offenses which is timestamped 3 minutes after mine. 75.210.75.165 (talk) 16:58, 24 July 2013 (UTC) Is it possible that I fixed the indent level on his post to make it line up for clarity? Yes, that's possible. The edit log will show it. Did I try to make it look like my words were his? No way! Did I target EditorASC? There is not a chance. I targeted statements with which I disagreed. Does Lfdder know me or have any bias in my favor? I haven't seen any evidence of that.75.210.75.165 (talk) 16:58, 24 July 2013 (UTC) I don't agree with the "fix" as it is at the moment as my replies now appear out of context, but that really isn't important to me. Because my neutrality could be questioned, I'm staying out of it. What is important is what goes into the article. 75.210.75.165 (talk) 15:59, 24 July 2013 (UTC) What matters is that we all agree that IFR was not canceled, that a visual approach is an IFR procedure in VMC, and that the flight was not under VFR. 75.210.75.165 (talk) 15:59, 24 July 2013 (UTC)

Boeing Customer Code
I don't know why do you reset my edit as Boeing 777-28E(ER) or Boeing 777-28EER in the infobox, especially that is to identify the operator or the one who owns the aircraft. If I use Boeing 777-200ER, it would be in general or for the aircraft only not with the operator. Don't mind if i will change the infobox with the details you have resetted and that is not necessary. — Preceding unsigned comment added by Pinas Central (talk • contribs) 09:53, 17 July 2013 (UTC)
- The customer code doesn't identify the operator (nor necessarily the owner), but the original customer. If Asiana were to lease their 777s from ILFC that ILFC bought first-hand from Boeing, the customer code would be ILFC's, but the operator would be Asiana. If Asiana were to buy ILFC's 777s, the customer code would, again, remain ILFC's. If the fact that Asiana bought this plane straight from Boeing is worth mentioning, then we should just say it. There's no need for fancy-pants codes. — Lfdder (talk) 10:19, 17 July 2013 (UTC)

"From what is known, the crew just turned in a truly lousy job of flying. Some would apparently like for this not to be known for a couple of years, when the accident will be all but forgotten." (Richard Collins is a well-known, well-respected, and widely published aviation expert.) 75.208.105.97 (talk) 21:01, 23 July 2013 (UTC)
Since ALPA is not a very well known name, a better section heading would simply be "Air Line Pilots Association". It is true that everyone needs to avoid speculation, and ALPA pointing that out is fine. While their job is to protect pilots, it is true that a large percentage of crashes have been traced to pilot error, and when the final or even preliminary report comes out this may be what the NTSB says, but it is true that speculating that it is pilot error is premature.

A visual approach is NOT an IFR procedure
Discussion not really related to improving the article
| |||
---|---|---|---|
"7-4-1. VISUAL APPROACH "A visual approach is an ATC authorization for an aircraft on an IFR flight plan to proceed visually to the airport of intended landing; it is not an instrument approach procedure. Also, there is no missed approach segment. An aircraft unable to complete a visual approach must be handled as any go-around and appropriate separation must be provided." [5] "A ceiling 500' above minimum vectoring altitude or minimum instrument altitude allows the controller to vector for a visual approach so long as visibility is three miles. Once the airport is in sight and reported so to ATC you can get a visual approach clearance. At larger airports you must report a specific runway before being able to get your clearance.... By doing so you relieve ATC of any avoidance accountability. A visual approach is not an IFR procedure even when on an IFR flight plan." [6] EditorASC (talk) 17:32, 24 July 2013 (UTC)

Injuries (non-fatal)
I see that the count of injuries in the infobox has been through some revisions including whether to use serious or critical (or the dangling adverb form critically). Let's talk about it. 71.60.50.60 (talk) 19:07, 28 July 2013 (UTC)
- Template:Infobox aircraft occurrence says simply "The total number of people injured in the accident/incident. Add in brackets if any of this number were people other than crew or passengers, or if it was everyone involved (e.g. "123 (4 on ground)", "123 (all)").". Martinevans123 (talk) 19:22, 28 July 2013 (UTC)
- Serious does not work, because that is not the word that was used by the hospitals. One reported 10 critical, another "about 3". Apteva (talk) 21:24, 28 July 2013 (UTC)
- Critical may be phrase used at the time but after a few weeks one would suspect if they were still alive they are no longer critical, we are not a news service so lets just keep it simple in the infobox and just list the total per the guideline, MilborneOne (talk) 21:32, 28 July 2013 (UTC)
- None or one are still listed as critical. Apteva (talk) 21:52, 28 July 2013 (UTC)
- Are the initially reported paralyzed injured still paralyzed? --Mareklug talk 22:36, 28 July 2013 (UTC)
- Probably, I have not heard otherwise. Apteva (talk) 22:58, 28 July 2013 (UTC)
- Whether they now are listed as serious condition is irrelevant. The relevant fact is how seriously injured they were as a result of the crash. I don't know where the line should be drawn to say which injuries are serious or not. 71.60.50.60 (talk) 03:02, 29 July 2013 (UTC)

- I understand the desire to split out count of persons who sustained serious injuries from those who merely sprained an ankle or got a brush burn in the escape. 71.60.50.60 (talk) 03:02, 29 July 2013 (UTC)
- Exactly. But the word serious never was used. The word used was "critical", meaning they could die from those injuries. Apteva (talk) 03:16, 29 July 2013 (UTC)
- Serious does not work, because that is not the word that was used by the hospitals. One reported 10 critical, another "about 3". Apteva (talk) 21:24, 28 July 2013 (UTC)
Is there anyone who has a problem with Injuries (non-fatal): 181 (13 critical)? 71.60.50.60 (talk) 04:20, 29 July 2013 (UTC)
- I do. Because, what will you do about noting the ones that became vegetables or (partially) lost the ability to move limbs, that might be returned to them after some incredible surgical work with stem cells years from now? It's best to avoid doing triage in this infobox parameter, and just report the number of injured. Everything else will be original research or synthesis. --Mareklug talk 11:33, 29 July 2013 (UTC)
- Yes just list the total anything else can be explained in the article. MilborneOne (talk) 11:31, 29 July 2013 (UTC)
If someone has a problem with Injuries (non-fatal): 181, please discuss it here. 71.60.50.60 (talk) 03:23, 30 July 2013 (UTC)
About
The word about is sprinkled through the article for a reason – that is what the sources said. They did not say the altitude was 1600 feet or that there were three critically injured passengers admitted to Stanford Hospital. They said "about 1600 feet", and "about 3". Removing the word about changes the article to saying things that we do not know. I have no problem with changing "about 3 seconds" to "3 seconds", because how far off can it be, but changing about 3 people to 3 people is misleading. The fact is that what we are dealing with is an event that we have very little factual information, and most of our sources give that information to us preceded with the word "about". For us to remove the word about is not correct. Apteva (talk) 02:02, 30 July 2013 (UTC)
Support. I favor using "about" on figures which sound precise but are not. The altitudes in the graph and in the text are 100' too high because they are pressure altitudes (not corrected for the local barometric pressure (29.82" Hg) which was lower than standard (29.92) at the time of the crash). 71.60.50.60 (talk) 02:46, 30 July 2013 (UTC)
- However, I oppose saying "about three people". 71.60.50.60 (talk) 03:16, 30 July 2013 (UTC)
- Restored, but left some of them out that were not important, like how long the airport was closed. But no, the altitudes given are definitely not "pressure altitudes", which are only used above 18,000 feet in the United States, according to our article on Flight levels, but they could have been measured with an altimeter which measures pressure and converts it to indicate altitude. Pilots enter the local pressure, such as 29.82, so that the altimeter will provide useful information. Apteva (talk) 03:13, 30 July 2013 (UTC)
- You keep saying that same silly thing, but educate yourself about FDRs and transponders and so forth. They record pressure altitudes. They do not record what is shown on the altimeter. So please stop saying that. 71.60.50.60 (talk) 03:16, 30 July 2013 (UTC)
- A pressure altitude of 100 feet at 29.82 is 6 feet above sea level, 7 feet below the runway. I do not believe the NTSB was saying that the aircraft was 6 feet above the waves when they said it was at an altitude of 100 feet and the pilots first noticed the aircraft speed was low. I believe they were saying just what they did say, that the plane was at an altitude of 100 feet. Now what the FDR said is immaterial, because if the FDR provided pressure altitude, the NTSB certainly knows how to convert pressure altitude, in this case, 194 feet, to altitude, when they said the plane was at 100 feet altitude. Apteva (talk) 06:26, 30 July 2013 (UTC)
- You keep saying that same silly thing, but educate yourself about FDRs and transponders and so forth. They record pressure altitudes. They do not record what is shown on the altimeter. So please stop saying that. 71.60.50.60 (talk) 03:16, 30 July 2013 (UTC)

throatsedits, seems to me. I don't perceive a cabal at work. Are you jesting? --Mareklug talk 06:40, 28 July 2013 (UTC)- The article seems pretty complete, and has a lot of editors working on it (139 are watching). I would recommend that it be proposed for GA or FA though. The two issues that are keeping it from B class, neither of which I am seeing, are "Coverage and accuracy", and "Supporting materials". Currently I do not see any citation needed or similar tags. Apteva (talk) 14:32, 28 July 2013 (UTC)

- I'd personally steer very well clear of any FA or GA nomination until the final investigation report has been published (not always a very swift process). I'd reply in more detail, but am obviously suffering from a torn-out throat at the moment. Martinevans123 (talk) 14:54, 28 July 2013 (UTC)

- I think it has to be appreciated that the sometimes random addition of facts as they become known will get ripped out and re-worked to be more coherent once the final report is published, after that it may be worth going for some sort of review but not before. While we wait if User:Checkingfax has more specific concerns that can be looked at then perhaps they can be listed and worked through. MilborneOne (talk) 15:43, 28 July 2013 (UTC)
- Agreed. Any article that is relatively new and evolving is likely to have "issues" that can be worked out if the editors collaborate. Robert McClenon (talk) 15:48, 28 July 2013 (UTC)
- What exactly is the problem with details which of of interest only a specific audience? Most articles have such details. This isn't merely a human-interest story or a single-vehicle crash by a driver on a foggy night. The causes are technical and complex. Most readers won't understand how two experienced airline captains could crash a perfectly good plane onto a large runway at a very modern airport in great weather. 71.60.50.60 (talk) 17:41, 28 July 2013 (UTC)

- While we definitely need to stay away from speculation on causes, all of our articles serve a dual purpose, a simple explanation to the non-technical, and technical details for those who are technically versed. Those dual purposes need to be balanced, and integrated in a manner that still serves both purposes. Apteva (talk) 22:29, 28 July 2013 (UTC)

Now the lead is too long, and is also misleading. "The engines had been at flight-idle for about 72 seconds, prior to impact" implies that the engines were idle for all 72 seconds prior to impact, when, by my math, they were not on idle for the 7 seconds prior to impact, but were on idle for 82-7=75 seconds. (corrected) Much of that time was legit, but they should have been reved up long before 7 seconds out. Where did 72 seconds come from? As to the summary, I have seen articles longshorter than that summary. What is wrong with waiting for the NTSB preliminary report? Apteva (talk) 01:15, 29 July 2013 (UTC)
- Done. I fixed the wording to put the time of 72 s in the correct place in the chronology. As for the time, I suppose that 72 s is the lower bound that the throttles were at idle. 71.60.50.60 (talk) 04:11, 29 July 2013 (UTC)
- Where did 72 seconds come from? I can suppose that 2 s is the lower bound, but the only times we have is the time they were set to idle, 82 seconds, and the time the throttles were advanced, 7 seconds, giving 75 seconds. Apteva (talk) 04:23, 29 July 2013 (UTC)

As to the go around being summarized as "but it was too late" that may have been true but is speculation. A go-around can be initiated successfully after the aircraft has crossed the runway threshold under normal conditions, but both are way way later than normal, and way, way below the normal decision altitude. This report says that Asiana has done six to eight times as many go-arounds at SFO than other airlines, the last one being July 19, but that really does not mean much.[8] Apteva (talk) 01:29, 29 July 2013 (UTC)
- That the go-around was initiated too late seems self-evident in that it was too late to prevent the crash. What other possibility might exist? 71.60.50.60 (talk) 03:04, 29 July 2013 (UTC)

Where did "engines accelerating" come from? The information we have is that the engines were at full thrust at impact, not that the engines were spooling up (accelerating). Apteva (talk) 04:23, 29 July 2013 (UTC)
- It was added in the revision as of 23:09, 28 July 2013 by EditorASC. What you are really asking is whether the engines got from 50% power to 100+% power within 7 seconds. It is possible. Were the N1 and N2 values disclosed? It could be settled. Perhaps EditorASC has a source. 71.60.50.60 (talk) 04:40, 29 July 2013 (UTC)
- We probably do not have details about the thrust at impact, but witnesses described it as full thrust ("it appeared and sounded as if they had applied maximum thrust"). About 3 or 4 seconds earlier it was at 50%, and another 3 or 4 seconds before that at idle. "Engines accelerating" does not seem like a reasonable lay translation for "spooling up". Apteva (talk) 06:15, 29 July 2013 (UTC)
- I want to see the N1 and N2 graph that confirms what you state (e.g., that the engines were at idle rather than at flight idle of 50%). What the witness said is probably correct, but more accurate information should be available. 71.60.50.60 (talk) 15:35, 29 July 2013 (UTC)
- I have no problem with leaving "spooling up" untranslated. Its meaning is easily inferred or researched. 71.60.50.60 (talk) 15:35, 29 July 2013 (UTC)

Can we combine the second and third paragraphs of the lead and ax half of it? They contain way too much detail now
Neither the US National Transportation Safety Board (NTSB) nor the South Korean Aviation and Railway Accident Investigation Board has issued a preliminary report. Both have held multiple press briefings, to provide updates on confirmed factual data with concomitant explanations. The aircraft's autopilot was turned off at an altitude of about 1,600 feet (490 m), and the remainder of the final approach was flown manually. The pilots thought the autothrottles would control the speed at the target approach speed of 137 knots, but that didn't happen. NTSB Chairman Deborah Hersman said one pilot expressed concern about the low airspeed, approximately seven seconds prior to impact by which time all engines had been at flight-idle for about 72 seconds. The stick shaker (stall warning device) activated 4 seconds before impact, and one of the pilots called for a go-around 1.5 seconds before impact, but it was too late.
The lowest pre-crash speed recorded by the FDR was 103 knots. At impact, speed had increased to 106 knots with the engines accelerating with takeoff power.

The aircraft's autopilot was turned off at an altitude of about 1,600 feet (490 m), and the engines reduced to idle. Both pilots thought that the autothrottle would limit the aircraft speed to the normal approach speed, of 137 knots. Seven seconds before impact the pilots realized they were too low and too slow, and applied power, but the aircraft continued to slow while the engines spooled up, reaching a low of 103 knots. About 3 seconds and 1.5 seconds before impact crew members were recorded calling for a go-around.

- Where? Apteva (talk) 19:19, 29 July 2013 (UTC)
- The problem is that you simplified so much that it is wrong. The altitude was about 1500'. The pressure altitude recorded by the FDR was 1600' (rounded). I hope that the engines were not at idle, but rather at flight idle. If there were at idle, that is a huge failure right there. Of course, there are two engines and thus two throttles, you know, a plural noun. The pilots thought that the speed would be maintained, not limited. The pilots realized that they were low and slow much further out than 7 seconds - they just didn't do anything about it. I could go on, but dumbing it down makes it sound stupid to anyone with technical knowledge. 71.60.50.60 (talk) 14:45, 29 July 2013 (UTC)
- The aircraft was descending at about 15 feet per second. The NTSB said "about 1600 feet". The reference we cite said "about 1600 feet". Why would we change that to 1500 feet, or make up that it was a pressure altitude? Altitude is often measured by the air pressure, using an altimeter, that correctly reads AGL by setting the instrument to the local atmospheric pressure. Pressure altitude is a term for what the altimeter reads if the pressure is set to 29.92 inHg, which is only done at higher altitude. See Pressure altitude and Flight level#Transition altitude. Aircraft have other means of measuring altitude, though, and this aircraft recorded some 14,000 parameters in the FDR. Pilots cross check instrument readings by referring to other instruments and regularly train with one or more covered or inoperational. Adding "flight idle" instead of "idle" is an unimportant distinction in the lead. To say that the pilots realized they were too slow at 103 knots is incorrect, as it was shortly after they were at 112 knots that they applied power because they saw they were too low and too slow (speed was first mentioned at 100 feet AGL, but sink rate was mentioned by the observing first officer in the cabin, multiple times). Due to the engines being at idle (whether that is called idle or flight idle, it is still at idle), it took 4 seconds for the engines to spool up to 50% power, and the aircraft speed continued to slow, reaching a low of 103 knots, and then increasing to 106 knots at impact. Apteva (talk) 19:19, 29 July 2013 (UTC)
- The FDR records pressure altitude. Please educate yourself. It is not something I "made up". It is fact. I agree that the pilots noticed that they were too slow long before the airspeed decayed to 112 kt. That's the point. The wording has been dumbed down so far that it is wrong. At what % power were the engine 4 seconds before they were at 50% power? And more importantly, where did you get these data? 71.60.50.60 (talk) 02:27, 30 July 2013 (UTC)
- The FDR records 14,000 parameters, including what the altimeter said and what the pressure was set to at the time. When someone says "altitude" they mean above sea level. When they say "pressure altitude" they are referring to something completely different. Pressure altitude is not used on approach or landing, because you would be looking for the airport hundreds of feet higher or lower than where it was. Apteva (talk) 02:58, 30 July 2013 (UTC)
- Correction, 1400 parameters. Early flight recorders only recorded 5 parameters, and only recorded pressure altitude, making the data difficult to interpret. Apteva (talk) 04:16, 30 July 2013 (UTC)
- You will eventually find out that the numbers you are using from ATC and from the FDR are uncorrected pressure altitudes and that your graph is misleading. 71.60.50.60 (talk) 05:22, 30 July 2013 (UTC)

Response: It is based on DH's comments, at her 2nd Press briefing. It is likely that the autothrottles were reduced to in-flight idle thrust (which puts them into "Hold Mode," even though they are still "armed,") about the same approximate time as when the AP was disconnected, but I refrained from saying that, since DH did not say that. In other words, to keep the accusations of "speculation" to a minimum, I said it as close to the way she said it, as possible, including using her frequent terms of "about," and "approximately," for which some have conveyed a tone of contempt/disdain.
[2nd DH News Brief, 130708]
- "At about 1,600 ft., the autopilot was disengaged...[22:30] and this was about 82 seconds prior to impact. At about 1,400 ft., their airspeed was approximately 170 kts. [22:46] This was 73 sec prior to impact. At about 1,000 ft., the AS was approximately 149 kts. And this was about 54 seconds prior to impact. [23:04] At about 500 ft., the AS was approximately 134 kts. And this was 34 sec prior to impact. At 200 ft., the AS was approx 118 kts. and this was about 16 sec prior to impact. [23:30] At about 125 ft., the throttles started moving forward. And the AS was approximately 112 kts. This was 8 sec prior to impact. [23:53] At about 3 sec prior to impact, the FDR recorded its lowest speed, at 103 kts. [24:06] At this time, the engs were at about 50% power, and eng power was increasing. At impact, the AS was approximately 106 kts." [24:25]
EditorASC (talk) 21:47, 29 July 2013 (UTC)
- The 72 seconds falls into the category of WP:OR. Clearly the throttle settings were changed, because the plane slowed from above 180 to 170 to 149 to 134 to 118 to 112 knots. At this point the instructor called for more power and reached for the throttles but found they had already been advanced, so the flying pilot may have noticed the speed before the instructor, but not until it was at 112 knots. 125 feet above the bay and 900 feet away from the seawall is not a particularly good place to be to notice that you are losing speed and already 22 knots too slow (change the last entry from 13 to zero if those altitudes are AGL instead of above sea level). Apteva (talk) 23:41, 29 July 2013 (UTC)
- No, "Clearly the throttle settings were changed" is false. Clearly what happened is the the flying pilot kept pulling back further on the yoke which reduces airspeed. Pitch controls airspeed. 71.60.50.60 (talk) 02:08, 30 July 2013 (UTC)
- This is not something that affects the article, and does not need to be discussed. We can not use our own personal knowledge. Mine is that on approach a pilot sets flaps and attitude and controls descent with the throttle. But it is my guess that while the plane was at a stable 180 to 200 knots the power setting was different from when the speed dropped to 170 knots, on a convex curve instead of a concave curve. Apteva (talk) 03:41, 30 July 2013 (UTC)
- The speed versus altitude curve is consistent with the pilot increasing pitch leaving power at flight idle during the 70+ seconds indicated. Power controls descent rate (more power → slower descent rate). Had the pilot not pulled back, speed would have remained higher. 71.60.50.60 (talk) 05:15, 30 July 2013 (UTC)

- No, "Clearly the throttle settings were changed" is false. Clearly what happened is the the flying pilot kept pulling back further on the yoke which reduces airspeed. Pitch controls airspeed. 71.60.50.60 (talk) 02:08, 30 July 2013 (UTC)

While the above could be added to the article, plus any other data points available from any of the other briefings, a picture is worth a thousand words, and the descent profile is much more useful. There is also one for the final 3 nautical miles that can be used, but the symbols used need to be cleaned up. Apteva (talk) 02:17, 1 August 2013 (UTC)
