What degree divergence is required for a helicopter's departure course to allow for simultaneous operations with an arrival?

A helicopter's departure course must diverge by a specific degree from an aircraft's arrival path to ensure safety during simultaneous operations. In this case, a divergence of 30 degrees is required. This degree of separation minimizes the risk of collisions by ensuring that the paths of the departing helicopter and the arriving aircraft do not converge too closely, which is especially important given the differences in speeds and flight characteristics between helicopters and fixed-wing aircraft.

By maintaining this 30-degree divergence, air traffic controllers can effectively manage the flow of both arrivals and departures, ensuring that the operations remain safe and efficient. The requirement is based on standard practices within air traffic management, particularly in busy airspace where safety and efficiency are of utmost importance.
