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 ratio is crucial for understanding how an aircraft performs during flight maneuvers. A higher load factor indicates that the aircraft can generate more lift than its weight, which typically occurs during turns and climbs, where the pilot may pull on the controls to increase the angle of attack.

The ability to generate lift greater than the aircraft's weight allows it to perform various maneuvers safely and efficiently, as well as influences the stall speed; a higher load factor increases the stall speed. Understanding load factor helps pilots maintain control and awareness of the aerodynamic limits of the aircraft, ensuring safer operations.
