What is the minimum altitude separation that must be established when both aircraft in a formation are blind?

The minimum altitude separation required when both aircraft in a formation are blind is 1,000 feet. This standard is established to maintain safe vertical separation between aircraft, particularly in circumstances where visibility is compromised for both pilots. By ensuring there is a 1,000-foot separation, the risk of collision is minimized, allowing for a buffer to account for any altitude deviations that may occur.

This altitude separation is critical in formation flying, especially under conditions where visual references are limited or lost, as pilots rely on instruments and communication to manage their relative positions. Maintaining this 1,000-foot vertical separation enhances safety and operational integrity within formation flying, ensuring that each aircraft can perform necessary maneuvers without the risk of inadvertently infringing on another’s altitude.
