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 ...
A flight control mode or flight control law is a computer software algorithm that transforms the movement of the yoke or joystick, made by an aircraft pilot, into movements of the aircraft control surfaces. The control surface movements depend on which of several modes the flight computer is in.
Cockpit controls and instrument panel of a Cessna 182D Skylane. Generally, the primary cockpit flight controls are arranged as follows: [2] A control yoke (also known as a control column), centre stick or side-stick (the latter two also colloquially known as a control or joystick), governs the aircraft's roll and pitch by moving the ailerons (or activating wing warping on some very early ...

The limit load can be found relatively easily by statistically analysing the data collected during the many hours of logged flights (which is continuously being gathered) but is generally predicted due to service of other aircraft before the design phase.
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.

[1]: 19 Artificial flight-control feel on the flight controls is achieved through the artificial-feel unit (AFU). One part of the AFU is the automatic spring-load adjusting system, known as the Arthur Q unit (Arthur unit), which adjusts the artificial feel on the control column depending on the elevator position and airspeed.
