What is load factor?

What is load factor?

• A. The maximum landing weight permitted.
• B. The control surface deflection required for a given bank.
• C. The rate of fuel consumption at cruise.
• D. The ratio of the current load to the aircraft's weight, indicating maneuvering load limits.

Answer: (D)

Load factor is the ratio of the load the aircraft’s structure must support to the airplane’s weight, expressed in g’s. It tells you how many times gravity the aircraft is effectively experiencing during a maneuver. In level, straight-and-level flight, lift equals weight, so the load factor is 1. In a coordinated turn or pull, the lift needed to provide centripetal force is greater than the weight, so the load factor rises above 1. The airframe is designed to handle specific positive and negative maneuvering load limits, which define how high or low the load factor can safely go. That’s why load factor is described as the ratio of current load to weight, indicating maneuvering load limits. It is not about maximum landing weight, control surface deflection, or fuel consumption.
