With the exception of class A airspace FAA control starts at the surface and extends to FL 600.
phlpsfrnk, sorry, not true. PCA (Positive Control Airspace) overlies the US 18,000-60,000', below that are several classes of airspace to include uncontrolled airspace which in some areas are ground level to 18,000'.
This is straying from the thread subject, so I'll discuss via PM.

eddieC,
I'll concede that point but the original point of my post was that the FAA control (classifications of airspace B, C, D, E & G) started at the surface. I agree with you that Sport_Pilot’s comments are patently false and I believe I showed that by posting the FAR 91.119 that he refers to and letting everyone read it for themselves what they actually say rather than his interpretation. There is a reason that bogeagle’s post about the UK regs and their similarities to ours are mainly because of the International Civil Aviation Organization (ICAO)
http://www.icao.int/Pages/default.aspx which the US and the UK are members of. All of the counties in the world that I have worked and flown in begin their air traffic control from the surface up.
I am constantly amazed by some of the interpretations that come out on these forums, “It is not possible to write in such a way that cannot be misinterpreted by a reader determined to do so.”
Regards
Frank
