Abstract:
A light aircraft with a fuselage wings and a belly and with provision to provide buoyancy to the entire aircraft, when needed to avoid said aircraft from crashing, so that said aircraft would descend slowly and land on terrain softly instead of crashing at a high descent speed, said provision being an electrical control circuit, compressed air tanks and solenoid-operated air valves with input and output ports, said control circuit comprising a voltage source, a first manual switch, a remotely operated relay in series with the solenoids of said air valves with all solenoids connected in parallel with said voltage source, said air valves and said tanks being mounted on said belly of said fuselage, with each of said air valve input ports being connected to a tank with piping, said remotely-operated relay having its circuit closed by the output voltage of an altimeter, said first manual switch for short-circuiting said relay; all buoyancy air valves, when opened, to blast air out vertically downward to provide buoyancy to said aircraft in its descent to prevent a plane crash on the surface below upon landing.
