What is the entry cone for ICAO course reversals?

The entry cone for ICAO course reversals is 60 degrees. This refers to the standardized angular range that is used to configure the flight path for aircraft that are executing a turn to reverse their course.

When a pilot initiates a course reversal, understanding the entry cone is crucial for maintaining proper airspace and ensuring safe operations. The 60-degree entry allows for sufficient space for the aircraft to safely establish a new flight path without committing too far off the original route, accommodating typical aircraft performance and navigation standards.

This angle not only aids in maintaining a smooth flight profile during the maneuver but also aligns with ICAO's regulations, which promote safety and predictability in air traffic management. The other angles, while they may be relevant in different contexts, do not apply to ICAO course reversals, as they do not meet the specific requirements and best practices outlined for this maneuver.
