Certainly true. ... the whole aviatic system (airspace boundaries, ATC clearances, traffic separation) is based on pressure altitude I agree with that statement too. .. If you are given an ATC clearance for a certain pressure altitude but fly GPS altitude instead, then you act exactly like that bozo who drives on the wrong side of the road. The only ATC clearances for a pressure altitude would be in the flight levels. Since the question was about setting a pressure altimeter, I would say that the flight levels are irrelevant. Below the flight levels, ATC clearances are for pressure compensated altitude above MSL, so yes it is based on pressure and not true altitude but close enough. My GPS gives me a calculated altitude above a theoretical sea level that's also close enough. ------------------------------- Travis Lake N3094P PWK |
