Does anyone know how fast a Boeing 767 can fly at low altitude? The top speed at cruising altitude is over 500 mph, but I've heard the following about flight at 700 feet altitude:
The power plant will max out at 330 mph. The plane will begin to shake itself apart at over 220 mph. At 700 feet altitude, the air is so thick that if you go too fast you max the rotation of the turbines, the engines can't suck in air, and the engine starts acting as a brake. Does this make sense? Where could I get more detailed information about flight limitations (or whatever you call it) of the Boeing 767? Thank you. This post has been edited by Ningen: Sep 2 2007, 04:19 AM |

Well
It would seem for the 707 used in the 1984 nasa cid test..... To exceed A 17 feet per second descent at 150 knots would probably have endangered the aircraft... (IMG:http://edit.81x.com/Authors/TruthExplosion/nasatext.jpg) page 10 http://testimony.ost.dot.gov/test/pasttest/85test/engen2.PDF Yet a 767 (Flight 175) descended at 76 feet per second at 512 knots ......a huge difference to that of the 707 used in 1984...... http://www.gwu.edu/~nsarchiv/NSAEBB/NSAEBB196/doc03.pdf |
