Load factor (aeronautics)

In aeronautics, the load factor is the ratio of the lift of an aircraft to its weight and represents a global measure of the stress ("load") to which the structure of the aircraft is subjected: n = L W , {\displaystyle n={\frac {L}{W}},} where n {\displaystyle n} is the load factor, L {\displaystyle L} is the lift W {\displaystyle W} is the weight. Since the load factor is the ratio of two forces, it is dimensionless.
