Minimum Height
How low are PFA type aircraft allowed to fly when not landing or taking off?
Forgive me if I'm wrong, but the way I read the rules implies that if a pilot knows for certain that he is clear of, essentially all man-made objects, he can be as low as he likes. The rules say 500 ft clear of persons, structures, vehicles and vessels, but I cannot find reference to height above the ground (excluding built up areas). If, for example, a pilot were over sparsely populated Scotland, or the sea, would he be operating illegally if he flew at less than 500 ft above sea level?
Many thanks,
John
