When should Merging Target Procedures (Traffic Calls) be applied?

Merging Target Procedures, which involve traffic calls, are primarily applied to enhance situational awareness and safety when dealing with high-priority aircraft, such as presidential aircraft and turbojet aircraft. These aircraft typically operate in controlled airspace where precise coordination and communication are critical, given their speed and the potential for high operational impact.

The reason this option is the most suitable is that it ensures that air traffic controllers give due priority to these aircraft, allowing them to navigate safely in busy airspace. This approach helps to mitigate the risks associated with close proximity between high-performance aircraft and other traffic, ensuring that all parties involved are well informed.

Applying these procedures specifically to this category of aircraft maximizes safety for all airspace users while allowing for effective management of traffic, particularly in complex operational environments. Making traffic calls for aircraft that fall outside this critical category may not have the same urgency or safety implications.
