A tight circling landing approach can double the risk of an aerodynamic stall

A circle-to-land maneuver requires a bank angle of up to 45 degrees, more than doubling the 20-degree bank typically used in straight-in approaches. According to the FAA, this significant tilt reduces the aircraft's vertical lift component by nearly 30 percent, as calculated by the cosine of the bank angle. Simultaneously, the sin² law dictates that drag surges twofold, creating a precarious energy state where the aircraft is closer to its critical angle of attack.
