If greater than 45 degrees of bank is required to complete the final turn, what is the recommended course of action?

The recommended course of action when a turn requires greater than 45 degrees of bank is to initiate a go-around. This is primarily due to the safety implications associated with high bank angles during final turns in flight operations. Exceeding 45 degrees of bank can significantly increase the risk of losing control or entering a stall, particularly close to the ground during critical phases of flight such as approach and landing.

When approaching these conditions, a go-around is the safest option. It allows for the pilot to re-establish a stable flight configuration and ensure control of the aircraft. This action provides the opportunity to reposition for another attempt at landing with proper parameters instead of risking an unsafe maneuver.

Continuing with the turn or banking to a lesser degree may lead to an unstable flight situation, and increasing throttle to maintain altitude doesn't address the inherent risk of an excessive bank angle. The go-around procedure helps maintain safety and control, aligning with the best practices in aviation procedures.
