Milt,
thank you for taking your time to respond. However, probably because my post was not very clear, you have not answered my question.
I am aware of what Vmc is, the risks associated with flying near or below that speed, as well as how to find it doing a simulated loss of control.
I also know how most of the factors you cited affect Vmc, except for GROUND EFFECT.
The question I posed in my thread was more of a theoretical brain excercise. Its a question that I wouldn't even dream about attempting a simulated loss of control in ground effect. However, I am interested in knowing how ground effect infuences Vmc (the speed at which loss of control occurs).
Many books write that ground effect influences Vmc, but do not explain how.
The FAA mandated that for certification of small aircraft (23.149), the published Vmc must be for an aircraft out of ground effect. (which might indicate ground effect DOES affect Vmc).
Can anyone shed some more light? (refer to my first post)
Thanks,
palgia
