For aircraft operating above FL290, what is the minimum vertical separation from Special Use or ATC Assigned Airspace?

For aircraft operating above Flight Level 290, the minimum vertical separation required from Special Use Airspace or ATC Assigned Airspace is established at 1,000 feet. This regulation is in place to ensure a safe vertical buffer between the operating aircraft and any activity that might be occurring within the designated airspace.

Maintaining this level of separation is essential for various reasons, including minimizing the risk of collision with military or other specialized operations that may have different operational characteristics and requirements. The 1,000 feet of vertical separation adequately provides the necessary margin to account for potential altitude deviations while guaranteeing safe and efficient air traffic management.

In this context, other separation standards would not comply with the safety protocols established for operations at these altitudes, as they could result in inadequate spacing that might jeopardize safety. Therefore, the regulation emphasizes the need for a standardized minimum of 1,000 feet of separation to preserve operational safety in the complex airspace above FL290.
