What term denotes the tactical grouping of two or more aircraft?

• A. Serial
• B. Chalk
• C. Formation
• D. Band

Answer: (A)

Two or more aircraft flying together as a coordinated unit are described by the term formation. This word captures the deliberate arrangement and spacing of the aircraft so they can operate as one group, share navigation and airspace, and provide mutual support during a mission. Common formation ideas include line abreast, echelon, or trail, each serving different tactical needs. Other terms you might hear are slang for the mission group, like chalk, which refers to the group assigned to fly together, but it doesn’t describe the flying arrangement itself. Serial designates the batch or batch count of aircraft for a mission rather than how they are positioned in flight, and band isn’t used to describe this concept.
