Talk:Approach plate

Penalties for using expired plates

Using expired plates is likely legal and non-problematic, as long as the procedure itself is not expired: procedures are not synonymous with plates, rather the plates are a graphical depiction of the procedures (where primary source is the regulatory procedure itself which may be amended at irregular intervals). So technically, if plate is "expired" (which by itself doesn't mean much, since they are just re-published on a regular schedule) but the procedure/amendment depicted is still current, then there shouldn't be any problem, even from legal perspective, with using that "expired" plate. There definitely shouldn't be any penalty associated with such use (indeed, I'm not aware of any such penalties being levied, at least within the US, as a matter of either policy or practice). Hence reliable sources for the statement in the article need to be provided, or the text should be removed (it's currently unsourced). cherkash (talk) 05:14, 8 January 2013 (UTC)[reply]

In Canada, just because the book of plates is expired does not necessarily mean that an individual plate for an approach is out of date - the date of last change is indicated at the bottom of each plate. I also agree that it's the procedure, not the acual piece of paper that must be up to date, so theoretically you could ink amend a plate to be current (not sure of it would meet legal requirements, but that's one for the lawyers and bureaucrats). I really don't think that the latter part of the last statement in the article adds anything anyway and should be deleted. That is to say, leave "Pilots are responsible for maintaining a current set" and delete ", and there are potential penalties that can be levied if a pilot is caught using expired plates during a flight in which they are required", which would be on a per country basis and is rather vague in any case.HiFlyChick (talk) 14:57, 8 January 2013 (UTC)[reply]

Done I've deleted the statement. Thank you for the input. cherkash (talk) 04:39, 11 January 2013 (UTC)[reply]

Limitations in distances

I've been looking around the various articles regarding landing of aircraft and I can't seem to find the answer I am looking for:

Flying commercial airliners into an international airport; what is the minimum distance to the landing threshold where the aircraft can be forced to make a procedure turn? How tight a turn? This is under normal operation according to the approach plate. This is obviously for noise reduction purposes.

I can't find a number but a 20 degree turn 7km from the threshold shouldn't be a problem? --Full steam (talk) 22:11, 5 March 2014 (UTC)[reply]

I don't believe there are specific standards related to this, which are part of approach procedures. Specific airports may have their individual noise abatement procedures, but unless the approach procedures were designed with noise abatement in mind, there are no other specific requirements. cherkash (talk) 20:22, 26 January 2015 (UTC)[reply]
