A Question about live&death In my opinion one of the most important instrument for keeping flying above ground is a Radio Altimeter. It is rather expensive, and most , or rather nearly all of ligth aircraft , X and U.L does no carry it. And this kind of planes , normally do not fligth at 30000 feet but very close to the hard ground . Now , you may find for a couple of bucks in any good hardware store a laser or ultrasonic mesure meters , that give you the exact distance from the instrument to the any wall up to a milimeter . As in ligth planes , the important fligth level is to keep the plane above ground , why instead of a professional radio Altimeter that give you thousand of feets , mobody adapted a commercial electronic mesuring devise that give you the most important data , the last feets to burial .
