RE: Boeing 757 Emergency Exits Question

I don't think it would really make much difference in getting out because you still have to get the rope out and throw it out the window then try and climb out without falling to the ground so I doubt it would make much difference. Yeah the doors on the passenger version of the 757 certainly open an...

I don't know about the Classic 737's but certainly on the <acronym title="Lauda Air (Austria)">NG</acronym> aircraft it wont be the PTU that you are hearing because the aircraft has to be in the air for the PTU to kick in.

RE: B767 Exits With Complete Power/hyd Loss?

The 767 doors have, as mentioned by NKP <acronym title="Sahara Airlines (India)">S2</acronym>, a coil/spring assembly in the roof above the door which assists in lifting the door. The spring strength is designed so that it makes it fairly easy to lift with the slide fitted but if the slide is not fi...

The 737 PTU is alot quieter than the 757 version but this is due to it being alot smaller and only powering the leading edge devices. This is from the 737 AMM: <i>...
