Performance Figures

Are the performance figures for cruise and Vne correct? I've checked the website and they match the manufacturer's specs but how can the cruise speed be higher than the never exceed speed? — Preceding unsigned comment added by 213.123.174.207 (talk) 13:51, 24 May 2013 (UTC)[reply]

Looks like a difference between indicated and true airspeed to me. 50.53.105.6 (talk) 04:49, 29 October 2013 (UTC)[reply]

Yes that is what it is. Vne is in IAS, while cruise is given in TAS, which at altitude is a much lower IAS. - Ahunt (talk) 11:32, 29 October 2013 (UTC)[reply]

220 max speed, 295 never exceed speed and ... 350 cruise speed ! no sense ! even with different standards... drlivingstone - 12 june 2020 - 18:27 (France) - — Preceding unsigned comment added by 78.120.143.61 (talk)

As explained above and as the article specs expressly explain, the cruise speed is true airspeed, while the Vne and max speeds are indicated airspeed. That is just the way airplanes that cruise at higher altitudes work! - Ahunt (talk) 18:02, 12 June 2020 (UTC)[reply]

No, the performance figures are not correct. I've seen your home page, Ahunt. Great work on the many vehicles! In this case, however, please refer to the Manufacturer's specifications tables for the correct figures, keeping in mind the fact there are four models of the Evolution, including a piston and three turbine horsepower classes: https://www.evolutionaircraft.com/aircraft/evolution-turbine/ Also, remember that both the FAA (Federal Aviation Administration) and ICAO (International Civil Aviation Organization) standards use "kt" and not "kn." Meteorological weather information for both winds aloft as well as the movement of weather systems as reported to all pilots is also given in knots, usually spelling out "knots," but occasionally using "kts" for the abbreviation. Thank you. Clepsydrae (talk) 05:35, 5 December 2020 (UTC)[reply]

Okay, thanks for the updated link.

Fixed Just to avoid any confusion I used just that one ref and re-sourced all the specs from scratch, although only a few had changed. You can note that on Wikipedia we do not use "kt" for "knot" as it is confused with the SI unit "kt" for "kilotonne". We use the SI abbreviation for knots, which is "kn". It is hardwired into the template, so cannot be changed. - Ahunt (talk) 17:59, 5 December 2020 (UTC)[reply]

I second this the performance figures should be given in IAS as TAS is situation dependent and not the standard for aircraft performance metrics. The Proccy (talk) 13:48, 2 February 2023 (UTC)[reply]

It is normal to report cruising speed in TAS, as if it was in IAS that would not be useful at all, plus IAS cruise speeds are usually not available in the refs anyway. Other speeds, such as stall speed are always in IAS. This is just reality in the world of aviation. There should be no confusion, as these are clearly marked in the specs for this article. - Ahunt (talk) 14:02, 2 February 2023 (UTC)[reply]

Apoligies upon further reading i concur with the TAS Staement. With so many articles with so little standardization it can be hard to rember what the correct system is. The Proccy (talk) 12:38, 13 March 2023 (UTC)[reply]

Infobox Image - fake?

The image on this page looks like it's been taken from a computer game, not a photo. There's no sign of the pilot in the cockpit and it just... doesn't look at all real. Does anyone else agree? TZHX (talk) 13:52, 7 October 2013 (UTC)[reply]

A quick look at it does indeed show that it is a fake and a very poorly done one too! Unless there is any really good reason to keep it it should be removed from the article. - Ahunt (talk) 15:23, 7 October 2013 (UTC)[reply]

Okay, lacking any further discussion for the last few days I will remove the image from the article. - Ahunt (talk) 21:03, 10 October 2013 (UTC)[reply]
