What is the primary cause of a stall if an aircraft rolls into a 60 degree angle of bank turn and pulls 3 g's at 200 knots?

In the context of an aircraft performing a banked turn, the primary cause of a stall is often linked to the excessive angle of attack. When an aircraft is banked at a high angle, such as 60 degrees, the lift vector is tilted, which can increase the effective angle of attack experienced by the wings. This elevation in angle of attack can lead the aircraft to approach or exceed its critical angle of attack, where airflow begins to separate from the wing, resulting in a stall.

During a turn, especially at increased g loading, the requirements for turn performance demand a corresponding increase in lift. To maintain this lift, the angle of attack must be increased. However, each aircraft has a maximum angle of attack it can sustain before stalling, beyond which the lift diminishes rapidly. Therefore, when the aircraft is subjected to the turning dynamics you've described (a high angle of bank and increased g forces), if the pilot does not manage the angle of attack properly, it can lead directly to a stall situation, even at a high airspeed.

In summary, while factors like g loading and the angle of bank are crucial in understanding the forces acting on the aircraft, it is the angle of attack that primarily dictates the stall condition, making it the
