The load factor, and in particular its sign, depends not only on the forces acting on the aircraft, but also on the orientation of its vertical axis. During straight and level flight, the load factor is +1 if the aircraft is flown "the right way up", [2]: 90 whereas it becomes −1 if the aircraft is flown "upside-down" (inverted). In both ...
Specifically, the load factor is the dimensionless ratio of passenger-kilometres travelled to seat-kilometres available. For example, say that on a particular day an airline makes 5 scheduled flights, each of which travels 200 kilometers and has 100 seats, and sells 60 tickets for each flight. To calculate its load factor:
The normal stall speed, specified by the V S values above, always refers to straight and level flight, where the load factor is equal to 1g. However, if the aircraft is turning or pulling up from a dive, additional lift is required to provide the vertical or lateral acceleration, and so the stall speed is higher.
A chart of velocity versus load factor (or V-n diagram) is another way of showing limits of aircraft performance. It shows how much load factor can be safely achieved at different airspeeds. [3] At higher temperatures, air is less dense and planes must fly faster to generate the same amount of lift.
For aircraft specification calculation in aeronautics, limit load (LL) is the maximum design load expected as the maximum load any aircraft will see during its lifetime, [1]
The flight mode of normal law provides five types of protection: pitch attitude, load factor limitations, high speed, high-AOA and bank angle. Flight mode is operational from take-off, until shortly before the aircraft lands, around 100 feet above ground level. It can be lost prematurely as a result of pilot commands or system failures.
