EDIT: I figured it out.........the speed of sound at 35,000 feet is approx. 690 mph. .785 Mach gives a speed of 541 mph.
So, clearly SWA is untruthful. The aircraft cannot average 590 mph under any circumstances without a tailwind. |
Why would you say that?
Most of their flights could have one hell of a tail wind.
They will fight for the best winds, tail or head.
Their average speed at altitude could easily average 590.
(Especially for the certain flights they used to make the commercial data from.)
A bit misleading, perhaps. But not clearly untruthful.
Also - Don’t ever mix the aircrafts certified standard operating specs with its actual flight data. They seldom, if ever, jive.
