Ground effect/Urban myth
I'm starting an instructor course on Tuesday so I've been diligently going through the urban myths to ensure that I'm not guilty of propagating them.
Can anyone point me to the thread that contains the full polemic about ground effect not being to do with pressure ? I've got Nick's urban myth thread which touches on the subject and refers to another thread, but I can't find the full monty.
Can anyone help with a reference ? If possible, I'd rather not rehash the debate here, at least until I've read the last one.
