RE: Need Info On 767 APU

And, because of that all the hydraulic systems. It also supplies air for main engine start and the air conditioning system. It is...

Theoretically, you can reach any speed the rotor is capable of assuming the engine holds together. I don;t have the AMM in front of me, thus don;t have the max N1 handy. But if 108.8% is the max, then yes you can meet it, assuming the other parameters (N2 (N3) or EGT) don't exceed. If you want to bu...

RE: Why Are These 767 Inlets Asymetrical?

You can drop them as an assembly, but why? Get the ducts and valves out of the way and out comes the ACM and the heat exchanger.

Hell, in 18 years exposed to the B757/767, I 've probably on seen 2 ACM and maybe one heat exchanger.

Very reliable system. At least the hardware.

I believe the point has been missed. Disregarding temperature and the pressure differential, what would it feel like. At FL390, the air is, roughly, 5 times less dense. So, the resistance the air will offer at, say, 440 knots, will be reduced by a factor of 5. That works out to a 'felt' pressure of ...

This pressure is sufficient to stop the wheel from turning during the 'up sequence'. This means normal terrain avoidance procedures can be used. If you use the alternate method (...

The actuator normally leaks at the piston seals.

The autospeed brake problem is actually pretty common. I'd say that at least 25% of our autospeed brake problems are caused by the tilt pressure switch/circuit. I've never seen the actual actuator cause the problem with auto speedbrakes.
