CFOT, I doubt there is a forum anywhere that can teach us things about anything in the world like CFOT does -
Airplanes Chief and ROTORHEAD - what?? -Fishing - Crabr1 - Annuities -777 - Real Estate - T+G Fan... and on and on...
I don't google anything. I CFOT anything I want to know. Not only will I get the right answer, I'll get 16 wrong answers, 42 jokes and a street fight all in one thread. It's entertaining and educational!

Most aircraft do have a “ weight on Wheels” / air ground mode system that allows certain systems to operate only in the Air or on the ground...Other jets, like the one in my avatar can deploy the thrust reversers in flight, the DC-8 could also. In the case of the C-17 (my avatar) we could deploy all 4 reversers and descend at 20,000 ft/minute. It came in handy at times flying into a combat zone, but you better be aware of what’s happening when you execute this tactic.
Beat me to it. I used to work at McDonnell Douglas. Some of my colleagues had previously worked as flight check engineers for Douglas Aircraft. On DC-8 check out flights, one of the thrills was to take the airplane to altitude and put the engines into reverse. Also, check out flights started in the morning, fiew to El Paso, a drive across the border for a session of boys R & R, and then flight back to Long Beach. The aerospace industry was a fun place to work up until the 70's.

One thing a jet engine can't do. A fart can transition from pneumatic drive to hydraulic drive.
