What is required for turbojets operating at or below 10,000'?

In the context of turbojets operating at or below 10,000 feet, individual coordination is required due to the higher density of interacting air traffic. At lower altitudes, especially around airports or in busy airspace, the air traffic control (ATC) task becomes more complex as there are various types of aircraft operating in proximity. Individual coordination ensures that each aircraft is accounted for and that their specific needs and flight profiles are considered.

This level of coordination helps to manage wake turbulence separation, navigate around conflicting flight paths, and maintain effective communication with pilots, leading to enhanced operational safety. It is crucial because the interactions and potential for conflict among aircraft are much higher at lower altitudes compared to cruising at higher altitudes, where the airspace tends to be more organized and separated.

Consequently, this requirement emphasizes the necessity of active and tailored communication and planning between ATC and turbofan aircraft to prevent any potential incidents or accidents due to miscommunication or oversight.
