What Would Happen If...

Wed Feb 28, 2001 9:34 am

What would happen if thrust reversers were applied during flight? Would the result be different for a 2,3 or 4 engined aircraft? I know that the result would not be good, but can anyone give me any specifics what would happen? Thanks in advance!!

It really depends on the aircraft/engine combo. For example, I believe that the reversers on the B-707 (or maybe it's the DC-8?) are used as speed breaks in the air. I do know, however, that a reverser deployment on a 200 series 737 is quite a ride, but not terminal! The reversers on the CFMs (737 - 300+) are not nearly as effective, due to their cascading design.
BTW...Deployed thrust reversers did NOT bring down 990!

Sometimes I go about in pity for myself and all the while a great wind carries me across the sky.

I read somewhere in a pilot manual to NEVER use the reversers in air. I didnt say why, but I guess it could be fatal.

Well, on a shroud type reverser (MD-80), in-flight deployment could rip them (the reversers) right off the aeroplane.

DC-8s use them in flight as speed brakes. NASA's Grumman Gulfstream G-2 uses them along with extended main gear to simulate the Space Shuttle (Yee Haw!) However, as a general rule, the checklist for T/R deployment in flight is located with the Emergency Procedures Checklists if that tells you anything. I've never had it happen in flight, but in the simulator, the resulting ride can be anything from mild to wild depending upon the airspeed, altitude, and power setting at which they deploy.
