True or False: Two primary factors must be present for an aircraft to spin; Stalled AOA and roll.

True or False: Two primary factors must be present for an aircraft to spin; Stalled AOA and roll.

• A. True
• B. False
• C. Always true
• D. None of the above

Answer: (B)

The correct statement is that the assertion about two primary factors — stalled angle of attack (AOA) and roll — being necessary for an aircraft to spin is indeed false. For an aircraft to enter a spin, it primarily needs to be in a stalled condition, which is when the wings are unable to generate enough lift due to an excessively high angle of attack. This stall condition is a key factor, but the presence of roll is not a mandatory requirement. Spins can occur during various scenarios where the aircraft is stalled, and while roll can contribute to the nature or characteristics of the spin (for example, a spin might occur in a specific orientation or direction based on how the aircraft is rolling), it is not an essential component for a spin to occur. Thus, stating that both a stalled AOA and roll must be present is incorrect, leading to the conclusion that the answer is false.
