A load factor greater than 1 will cause the stall speed to increase by a factor equal to the square root of the load factor. For example, if the load factor is 2, the stall speed will increase by a ratio of 2 {\displaystyle {\sqrt {2}}} , or about 140%.
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 V-n diagram showing V S (stall speed at 1G), V C (corner/maneuver speed) and V D (dive speed) 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]
As stalling is due to wing loading and maximum lift coefficient at a given altitude and speed, this limits the turning radius due to maximum load factor. At Mach 0.85 and 0.7 lift coefficient, a wing loading of 50 lb/sq ft (240 kg/m 2 ) can reach a structural limit of 7.33 g up to 15,000 feet (4,600 m) and then decreases to 2.3 g at 40,000 feet ...
Stall speed or minimum steady flight speed for which the aircraft is still controllable in a specific configuration. [7] [8] V S R: Reference stall speed. [7] V S R 0: Reference stall speed in landing configuration. [7] V S R 1: Reference stall speed in a specific configuration. [7] V SW: Speed at which the stall warning will occur. [7] V TOSS
The specific altitudes and speeds of the coffin corner will differ depending on weight, and the load factor increases caused by banking and pitching maneuvers. Similarly, the specific altitudes at which the stall speed meets the critical Mach number will differ depending on the actual atmospheric temperature.

V A is the design maneuvering speed and is a calibrated airspeed.Maneuvering speed cannot be slower than and need not be greater than V c. [4]If is chosen by the manufacturer to be exactly the aircraft will stall in a nose-up pitching maneuver before the structure is subjected to its limiting aerodynamic load.
