What effect does a high bank angle have during a turn?

A high bank angle during a turn substantially increases the load factor experienced by the aircraft. This is because when you bank an aircraft, you are essentially changing the direction of lift. In a level turn, the lift vector is tilted inward, which means that a greater portion of the lift must counteract the centripetal force needed to maintain a curved path.

As the bank angle increases, the load factor increases, which places additional stress on the aircraft structure and can lead to higher stall speeds. For instance, a bank angle of around 45 degrees can result in a load factor of approximately 1.4 times the weight of the aircraft, meaning the pilot must be aware of this impact to prevent stalling.

Understanding this principle is crucial for safe maneuvering, especially in a sport pilot context where aircraft are often lighter and may have different performance characteristics compared to larger aircraft.
