What happens to the stall speed if the load factor is increased during a turn?

When the load factor increases during a turn, the stall speed of the aircraft also increases. This phenomenon occurs because as the aircraft banks into a turn, the angle of attack must be increased to maintain lift against the increased load factor. The load factor during a turn can be significantly greater than one, depending on the radius of the turn and the bank angle used.

As the load factor increases, the aircraft experiences more weight effectively acting against its lift-capability, requiring a higher angle of attack (and thus a higher stall speed) to maintain level flight. The relationship between load factor and stall speed can be expressed mathematically as follows: the stall speed increases with the square root of the load factor.

Thus, if you were to increase the load factor to, say, two times the normal weight (in a steep turn), the stall speed would become approximately 1.41 times (the square root of 2) the normal stall speed in level flight. This significant increase underscores the importance of managing bank angles and understanding load factors during flight, especially in performance-critical maneuvers.
