any idea why mode C is to be operated on the ground in DFW? Might that be that aircraft in flight can then inhibit display of such aircraft as NSEU says?
NSEU, you say "There will be no display of aircraft on the ground if your own aircraft descends below 1700' Rad Alt Height. "Ground aeroplanes" are those considered to be within +/-380 feet of ground level for Mode C aircraft..."
Do you think this is determined by comparing the target's mode C altitude to your mode C and your rad alt? If so, then perhaps I would not get a climb climb climb if I was above an aircraft taking off, when it is still below 380 feet above the airport?
thanks,
