When in a procedure turn at FEHXE, what indication signals it’s time to turn inbound?

In a procedure turn scenario, the point at which you initiate the turn back toward the inbound approach is typically defined by the distance from a designated fix, in this case, FEHXE. The recommended distance for turning inbound allows for adequate time and space for the aircraft to stabilize in the correct flight configuration prior to intercepting the approach course.

According to standard procedures, when 4 DME miles from the fix FEHXE, it is standard practice to start the inbound turn. This distance is derived from the need for adequate spacing and handling characteristics of various aircraft, ensuring they can safely intercept the inbound course without excessive banking or altitude changes.

This helps ensure that the aircraft is well aligned for a stable approach, making 4 DME miles the correct indication for when to turn inbound.
