Re: Why fuel driven actuators?

I once flew an aircraft that had pneumatically actuated thrust reversers. There’s an infinite supply of air, too, in an engine that is running.

Re: Is it dangerous when aircraft carry fuel in a center tank beneath the passenger cabin?

You’re only going to get 17000 lb onto a 737 if you can’t use your center tanks, out of a potential capacity around 46,000 lb.

Air Florida had thrust to spare but what the DC10 really could have used was a few knots more airspeed. If they hadn’t been so dead nuts precisely pitching to V2 that wing wouldn’t have stalled.
