What is the required lateral separation between aircraft at or above FL600 in radar conditions?

The required lateral separation between aircraft operating at or above FL600 in radar conditions is 5 miles. This standard is established to ensure safe distances between high-altitude aircraft, where speeds and densities can be greater, necessitating a wider margin for error.

At altitudes above FL600, the increased variability in performance characteristics and the potential for more complex air traffic scenarios make it crucial to maintain this level of separation. This helps minimize the risk of wake turbulence and ensures that controllers have adequate space to manage and direct air traffic effectively.

In contrast to lower altitudes, where different separation standards apply, the requirement for 5 miles at FL600 reflects the need for heightened caution and operational safety in high-altitude environments.
