Re: What cockpits are particularly noisy?

The noisiest aircraft I’ve experienced is the Cessna 337 (or fixed gear variant the 336). Not only are both engines directly mounted to the cabin, the rear engine is running in the turbulence of the front engine further adding to the noise and vibration.

RE: Boeing 757 Door Design

A 757 door is significantly heavier than a 737 door and thus the handle needs to be bigger to give you the leverage to overcome the weight to the door when you try to open it from outside. This is why the handle is too long to stow horizontally so has to be stowed diagonally. The extra weight of the...

Just an idea. Could this sound be created as the slats are extened creating a sort of reed like that of a wood wind instrument? It would explain why you only hear it for a few seconds as the reed disapears when the gap between the slat and the leading edge opens up.
