What is the bank angle that results in a 1,500' altitude loss?

The correct bank angle that results in a 1,500-foot altitude loss during a turn is associated with a 45° bank. When an aircraft is in a banked turn, the lift vector changes, and a portion of the lift must counteract the weight of the aircraft while also providing the necessary centripetal force for the turn.

At a 45° bank, the load factor increases significantly, leading to a downward component of the lift, which can effectively result in an altitude loss if not managed correctly. The relationship between bank angle and altitude loss is important for pilots to understand, particularly in situations where the turn is not coordinated with proper altitude maintenance.

For instance, the more steeply you bank, such as with a 60° bank, the greater the load factor and descent rate can become, further exacerbating altitude loss. Conversely, lower bank angles yield less significant altitude loss but do not achieve the same horizontal maneuver capabilities. In this context, a 45° bank is optimal for achieving a balance between maneuverability and altitude maintenance, which is why it aligns with a loss of approximately 1,500 feet under many conditions.

Understanding this relationship is key for effective flight maneuvering and maintaining situational awareness while managing
