Which term describes the group of two or more aircraft in a mission?

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

Answer: (C)

In mission planning, the group of two or more aircraft that are assigned to execute a specific sortie is called a serial. This term defines the actual set of aircraft that will fly together to complete that mission, coordinating timing, tasks, and airspace so everyone knows who is part of the same run.

This differs from a formation, which describes how the aircraft are arranged and positioned relative to one another while flying, not the designation of the group for the mission. Other terms like chalk or lift don’t serve as the official designation for the mission group in this context; chalk is more of a ground/throughput label, and lift refers to the act of lifting or the payload rather than the mission group.
