What is the power loading?

• A. 15.2 lbs/hp
• B. 12.3 lbs/hp
• C. 18.0 lbs/hp
• D. 20.0 lbs/hp

Answer: (A)

Power loading is the amount of weight the engine has to move per horsepower, expressed as pounds per horsepower. It’s calculated by dividing the gross weight by the engine horsepower (power loading = weight / horsepower). A lower number means each horsepower has to move less weight, which generally translates to better takeoff and climb performance. If the aircraft weighs 2,280 pounds and has a 150-horsepower engine, the power loading would be 2,280 ÷ 150 = 15.2 lb/hp. That matches the given value, so 15.2 lb/hp is the correct figure for this scenario. The other numbers would require different weights or engine power.
