How is the term "load factor" defined in aviation?

The term "load factor" in aviation is defined as the ratio of the lift generated to the weight of the aircraft. This metric is crucial for understanding the performance of an aircraft during flight. When an aircraft is in straight and level flight, the lift must equal the weight for stability. However, during maneuvers, the load factor can change significantly. For example, in a turn or during acceleration, the lift generated must exceed the weight, thereby increasing the load factor.

A load factor greater than one indicates that the aircraft is experiencing more lift than weight, which typically occurs during maneuvers such as climbing, turning, or entering a steep bank. Conversely, a load factor less than one suggests that the aircraft is not generating enough lift to counteract its weight, such as during a descent.

Understanding load factor is essential for pilots and mechanics alike because it directly impacts structural integrity and aircraft performance. If an aircraft consistently operates at high load factors, it can lead to increased stress on the airframe and potential structural failure if not properly managed.

In contrast, other choices do not accurately capture the definition of load factor. The weight of the aircraft divided by total lift generated would provide a reverse ratio, which does not represent how load factor is conventionally
