Under what condition may aircraft operate in formation flight?

• A. Formation flight is prohibited except by prior arrangement with the pilot in command of each aircraft
• B. Formation flight is allowed if you have a valid weather briefing
• C. Formation flight is permitted with ATC approval only
• D. Formation flight is allowed at any time without special arrangements

Answer: (A)

Formation flight involves operating aircraft in close proximity, which increases the risk if there isn’t a clear, agreed-upon plan. Because safety hinges on every pilot knowing the exact role, spacing, maneuvers, and contingency actions, the operation must be arranged in advance with the pilot in command of each aircraft. This arrangement ensures each PIC consents to the plan, understands their responsibilities, and is prepared to maintain safe separation and communicate effectively.

Weather briefing, ATC approval, or flying without special arrangements do not by themselves authorize formation flight, since they don’t guarantee the mutual understanding and coordinated actions required for close-formation operation.
