power loading


Also found in: Dictionary, Thesaurus, Wikipedia.

power loading

The ratio found by dividing the maximum gross weight by the brake horsepower produced by all the engines. The term is applicable to both fixed- and rotary-wing aircraft. The jet equivalent for this term is thrust loading.

In the power loading equation, Formula 2 on page 5, the word "generated" preceding horsepower connotes engine horsepower is not constant.
Consequently, power loading is adversely affected, and increases to 17.
Twin-engine airplanes (propeller and jet) may fly under two different power loading conditions, with both engines operative and one engine inoperative (OM).
During OEI conditions, however, power loading increases significantly for twin-engine airplanes.
It also includes a practical understanding and application of relevant aerodynamic concepts like wing and power loading.
For example, when maximum takeoff performance is desired--as during a short-field takeoff--a pilot may decrease wing loading and power loading by reducing useful load.
To accommodate the higher wing loading, the MU-2 has a lower power loading of 7.
Airplanes engaged in fire-fighting and parachute operations, as further examples, routinely see wide variations in wing and power loading during a single flight.
Determining your airplane's wing and power loading is a simple matter of running a couple of numbers.
For example, wing loading and power loading for a Cessna 172S NAV Ill with a wing surface area of 174 square feet, an engine generating 180 hp, and operating in the Normal Category at a maximum takeoff weight of 2550 pounds are presented in Formula 3.
