WebPerformance Factors. A helicopter’s performance is dependent on the power output of the engine and the lift production of the rotors, whether it is the main rotor (s) or tail rotor. Any factor that affects engine and rotor efficiency affects performance. The three major factors that affect performance are density altitude, weight, and wind. Web29 de jun. de 2024 · Altitude means height above the ground or above the sea level.Common uses include aviation (flying, parachuting, gliding), and geography/surveying.In geometry it is also used as the height of the object itself.
