What is the standard additional separation from other aircraft in formation flight?

In formation flight, the standard additional separation from other aircraft is typically 1 mile. This practice is primarily intended to ensure safety while allowing aircraft to operate closely together in a controlled manner. The 1-mile separation allows for adequate spacing without compromising the tactical advantages or operational benefits that can be gained from flying in formation.

Formation flying requires precise control and coordination among the participating aircraft, and this 1-mile standard helps to mitigate the risks of wake turbulence or other potential hazards while ensuring that the aircraft can maintain their intended flight paths effectively. The relatively short distance is practical for maintaining communication and visual contact within the formation while still providing a buffer zone to manage safety.

Longer separations, such as 2 miles, 3 miles, or 5 miles, are typically more applicable to standard en route or IFR separation standards between non-formation aircraft in less controlled environments, where the focus shifts to minimizing conflict in busy airspace rather than maintaining a close-knit formation.
