Claim 0:
1. A fixed wing aircraft having a pilot compartment and an engine, comprising:
apparatus adapted to control flight attitude, and direction including at least a first reversible electric motor implemented in a first fixed wing driving a first two-blade propeller in a first slot and a second reversible electric motor implemented in a second fixed wing driving a second two-blade propeller in a second slot, the first and second two-blade propellers are adapted to be constrained wholly within the first and second slots when not being driven by their associated electric motor;
a controller adapted to vary power of the engine;
sensors sensing at least altitude, airspeed, power level, and aircraft attitude;
a CPU coupled to a data repository, to the sensors and to actuators adapted to change the flight attitude and direction and to vary power at the engine; and
safe flight envelope data and conditions stored in the data repository defining flight conditions at boundaries of safe and unsafe operation;
characterized in that the first and second slots are positioned, one each, proximate a wing tip on the first and second fixed wings and include a length oriented parallel with the first and second fixed wings, the CPU monitors the sensors while the aircraft is in operation, determines if flight status is outside the safe flight envelope, and if so, drives appropriate actuators to manipulate the apparatus adapted to control flight attitude and direction and/or the controller adapted to vary power of the engine including at least the first and second electric motors driving the first and second two-blade propellers in a programmed manner until the flight status is within the safe flight envelope.
