What happens to stall speed when load factor increases during a coordinated turn?

When load factor increases during a coordinated turn, stall speed increases. This occurs because the stall speed of an aircraft is directly related to the load factor, which is the ratio of the lift produced by the wings to the weight of the aircraft.

In a coordinated turn, as the aircraft banks to change direction, the load factor increases due to the additional lift required to counteract the increased weight component acting towards the ground resulting from the bank angle. Since stall speed is determined by the square root of the load factor multiplied by the weight and divided by the wing area, an increase in load factor results in a higher stall speed. This means that the aircraft must fly at a higher true airspeed to maintain flight and avoid entering a stall during the turn.

Understanding this relationship is crucial for pilots, as it emphasizes the need for increased awareness of speed management during maneuvers, particularly when turning, to avoid inadvertently entering a stall.
