Ofc, I was meaning on subtle sounds that are heard differently when idle or high/full throttle. Thank you Sith. Everyone else as well. Since ED is working together with TFC I believe that they could obtain valid sources on this subject eventually and make it well balanced. No need to guess anything :) Also, as others mentioned and in accordance with Siths comment - yes, this is not just a game it's a sim, but being unable to reproduce some physical effects on the pilot could be made up via sound, visual effects (like blackout does) and introducing for example - pilot being wounded which result in less responsive controls (which compensates that a wounded pilot needs more effort to control the plane and is more obstructed in it).
