How many degrees of bank should typically be used in the final turn?

In the context of aerobatics and general flight maneuvers, a 30-degree bank angle is typically considered optimal for the final turn during approaches or landing configurations. This bank angle strikes a balance between maintaining sufficient lift and control of the aircraft while also enabling a stable, efficient turn.

Using a 30-degree bank helps ensure that the aircraft remains within a manageable performance envelope, allowing for a good rate of turn without overly stressing the airframe or causing excessive aerodynamic drag. Additionally, this bank angle provides adequate clearance from obstacles while aligning the aircraft with the runway.

Other bank angles, while they can be effective in certain situations, may not provide the same level of control and efficiency during a final approach. For instance, a very shallow bank, like 15 degrees, may result in a slower turn radius, while steeper angles, such as 45 or 60 degrees, could lead to higher load factors and may push the aircraft closer to stall conditions if not managed carefully. Thus, a 30-degree bank is recognized as a practical standard for this phase of flight.
