Talk:Overspeed (aeronautics)

Untitled
An aircraft can fly too fast but this is not usually termed overspeed which is a term more usually used in relation to engines. See overspeed (engine). Note that the V ne article does not mention the term "overspeed". This article would be better deleted and the very few articles which link here should link intstead to V ne.

Note also that there is no one speed which is too fast for an aircraft in all circumstances. There is e.g. also Va. Paul Beardsell 07:12, 14 September 2006 (UTC)

The term 'overspeed' ,at least on the MD-88, (and sister aircraft 82, etc--) is a specific waring given by the automated flight systems when a pilot exceeds the airspeed that the aircraft is set to detect. This relates to stability of aircraft, frame, flight, etc. It is one of a number of emergency warnings that can be sounded out by the ACFT, such as 'pull up,' etc as such it does have encyclopedic value. In other words if you should exceed this airspeed, there is no way unless you are deaf, and in some cases blind to a red cockpit, that you will know, on equipped ACFT. (The more appropriate term than 'speed' would be 'velocity,' as far as I have experienced it relates ONLY to airspeed, with the sole purpose of protecting the aircraft from stress it cannot or should not handle, remember it is a vector so x+y+z. Speed relative to ground is of no interest or meaning, here. Most aircraft can land at/or near full speed, the limiting factor is the length of runway, and to a lesser extent the tire wear, on the landing-gear. Here you could go too fast for the runway and never receive a warning, so when landing at a short and difficult to approach runway, always be mindful of wind and ground speed, i.e. look up landing at Toncontin on youtube and you see why... (Amongst others there is an AA video of a 73X that only makes it on third attempt.) Kris --->read above >::: Strongly recommend this article be nominated for deletion as it has no encyclopedic value. The term "overspeed" is very broad in meaning and while it may sometimes be used by journalists in reference to aircraft is not part of the lexicon of pilots or the aviation industry in general.Geoffrey Wickham 04:32, 18 May 2007 (UTC)


 * Overspeed was accepted terminology in consensus-based aviation standards, for example see this SAE standard: Overspeed Warning Instrument (Turbine Powered Subsonic Aircraft). I agree that the article needs cleanup, and may be a merge candidate, but it should not be nominated for deletion, because it will remain as a redirect after a merge. More source based research (and less personal opinion) is needed to resolve this. Dhaluza 09:38, 18 May 2007 (UTC)


 * Hi User:Dhaluza and thank you for your contribution to this discussion. The problems I have with this article are threefold. 1) It is such a narrow subject as to be unworthy or barely worthy of an encyclopedic entry. 3) There is no single speed which is "overspeed" for an aircraft which you, as a flight instructor, will surely agree. 3) The subject of "overspeed" is already thoroughly covered in Flight envelope, so to fully discuss the meanings of overspeed in this article would be unnecessary duplication.
 * It may be of encyclopedic value to maintain the title Overspeed (aircraft) but delete the existant text and redirect to Flight envelope. BTW:the ref you cited is marked (Non current Nov 1996). Regards Geoffrey Wickham 00:26, 19 May 2007 (UTC)


 * I think "overspeed" is a broader term that covers both Vne (structural-flight envelope) as well as Mach limit (transonic). So it may be that the other articles need to be merged here, rather than the other way around. As I said, more research is needed. Dhaluza 01:00, 19 May 2007 (UTC)
