What additional factor must you consider when performing steep turns?

When performing steep turns, the primary additional factor to consider is the higher angle of attack. During a steep turn, the aircraft's bank angle increases, which in turn requires a corresponding increase in angle of attack to maintain altitude. This is because the load factor (g-forces) acting on the aircraft increases in a turn due to the bank angle; to counteract this increased load factor and keep the airplane level, the pilot must pull back on the yoke or stick, thereby increasing the angle of attack.

An increased angle of attack comes with its own risks, as it brings the aircraft closer to the stall angle. Pilots must be vigilant to avoid stall conditions, particularly since the increased load factor in a turn can lead to a stall at a higher airspeed than in level flight. Therefore, managing the angle of attack is crucial to ensure safe maneuvering during steep turns.

The other factors such as bank angle, airspeed, and drag are certainly relevant in the context of steep turns but do not directly address the primary concern of maintaining control and safety in these maneuvers in the same way that managing the angle of attack does.
