The Certificate of Waiver is the foundational legal document for the air show. It waives specific Federal AviationRegulations for the duration and location of the event. Without it, the aerial demonstrations you’re managingare not lawful.
And the Air Boss is required to read the COW in full — not a summary from the event organizer, the actualdocument.
Non-negotiable. The COW defines the Flying Display Area, authorized maneuvers, separation distances, and any special provisions. Every condition and limitation in that document is binding on you. Before you assume duties, you must have verified the dates, times, geographic coordinates, and the list of waived FARs.
What about the Certificate of Authorization? That gets less attention in training, but it comes up.
The COA covers operations in controlled airspace — Classes B, C, and D — and for public aircraft and UAS operations. Conceptually parallel to the COW but for different operator types. Review the COA with the same rigor. If there’s a UAS operator at your show working under a COA, you need to understand what that document authorizes and what it restricts.
FAA Form 7711-2 is the application that produces the COW or COA. The Air Boss doesn’t typically submit it, but should understand it.
Understand it and review the draft before it goes to the FSDO. Errors in the application become errors in the issued document. Minimum lead time is 90 days, and 120 is the practical recommendation. A COW with incorrect coordinates or dates is a problem you discover on show day — which is the worst possible time.
