What is the minimum vertical separation required for aircraft operating at or below FL290 from Special Use or ATC Assigned Airspace?

The minimum vertical separation required for aircraft operating at or below Flight Level 290 (FL290) from Special Use or ATC Assigned Airspace is 500 feet. This standard is in place to ensure adequate separation between aircraft and potentially hazardous airspace, as Special Use Airspace (SUA) can include areas such as military operations areas (MOAs), restricted airspace, or airspace designated for other specific uses.

The requirement of 500 feet provides a buffer that enhances safety by reducing the risk of incursions into airspace where unusual or hazardous operations may be occurring. The regulation reflects an emphasis on maintaining safe distances, allowing for considerations such as aircraft performance and operational factors. Understanding these requirements is essential for effective air traffic management and ensuring pilot adherence to safety protocols.
