I'm with Intruder. A lot of these posters appear to be simply
flight sim gamers like this one and I don't bother with 'em.
You can tell by the simplicity of the question construction.
For instance here's a typical example of the same question
being asked by a non-gamer -
Could somebody help me please? I'm studying Gas Turbine
Theory and I can't get my head around the physics of why
reverse thrust is more effective at higher speeds than lower
ones.
Also are cascade reversers more effective at lower speed than
the bucket variety? Thanks.
