When using overhead marshal, the assigned outbound penetration bearing should maintain a minimum of how many degrees clockwise from the reciprocal of the final bearing?

In the context of air traffic control, particularly during an overhead marshal, maintaining the correct outbound penetration bearing is crucial for ensuring the safe and efficient separation of aircraft. The requirement that this bearing should maintain a minimum of 25 degrees clockwise from the reciprocal of the final bearing is based on established safety protocols that are designed to prevent potential conflicting flight paths as aircraft are marshaled into position for landing or other maneuvers.

The 25-degree minimum ensures that there is an adequate buffer between the inbound and outbound paths of aircraft. This helps to limit the risk of collision, especially in high-traffic environments such as around a carrier or large airport. By adhering to this guideline, air traffic controllers can maintain clear and predictable flight paths for aircraft, which is essential for effective traffic management in the airspace.

This standard is in place to promote safety and streamline the flow of air traffic, particularly during complex operations like overhead marshals where multiple aircraft may be undergoing various phases of approach and departure in close proximity.
