Which of the following is a characteristic of a normal stall?

A characteristic of a normal stall is that both wings stall simultaneously. In a proper stall situation, the airflow over both wings is disrupted at roughly the same time due to a uniform increase in angle of attack, which is when the wing begins to exceed its critical angle of attack. This uniform stall behavior helps pilots to manage the aircraft and provides predictable handling characteristics, which is essential for recovery.

When both wings stall simultaneously, the aircraft’s behavior is more manageable. This contrasts with situations where one wing stalls before the other, which can lead to an uncoordinated flight condition and possibly result in a spin. A normal stall is primarily demonstrated in straight and level flight, highlighting that it can occur under controlled conditions, which is critical for pilot training and understanding aircraft behavior during what is an expected aerodynamic phenomenon.
