What does the load factor describe in relation to an aircraft's weight?

• A. The ratio of a specified load to the total weight of the aircraft
• B. The ratio of fuel weight to total weight
• C. The ratio of passenger weight to total weight
• D. The ratio of wing area to weight

Answer: (A)

The load factor tells you how hard the airframe must work by comparing the load on the wings to the aircraft’s own weight. It’s essentially the lift the wings must produce divided by the aircraft’s weight, so it represents how many times the aircraft’s weight is being supported. In straight-and-level flight, lift equals weight, giving a load factor of 1. In maneuvers like turns or pull-ups, lift must exceed weight to change the flight path, so the load factor becomes greater than 1 and increases with maneuver intensity. So the load factor describes the ratio of a specified load (the wing-lift load) to the total weight. The other options describe fuel fraction, passenger weight fraction, or wing loading, which are different concepts.
