> 199ft in the US .. which insanely low to aircraft (not helicopters) not near an airfield.
Not to geophysical exploration pilots running gravity, radiometrics, magnetics, etc in modified crop dusters at 80m ground clearance and 70m/s.
199 ft ~= 60m which a survey line might bottom out at when draping over ridges, etc.
Literally millions and millions of line kilometres are flown at those specifications, entire countries (like Mali, Fiji, Australia, etc) have been covered at 200m line separation.
Insanely low for yourself is pretty much just another day in the cockpit in just another month long survey job for survey pilots.
Not to mention actual crop dusting and other STOL grunt work.
