Propeller-driven aircraft with improved stability about its yaw axis

Propeller-driven aircraft (30) comprising an engine (31) providing mechanical engine power for rotating a propeller (32), an engine limiting unit (35), an engine control unit (37) for controlling the mechanical engine power of the engine (31), a system (36) for measuring the airspeed and providing information concerning the airspeed to the engine limiting unit (35), wherein the engine limiting unit (35) automatically reduces the mechanical engine power at airspeeds below a certain first airspeed value (V1).
