Within a lift, what is the term for each individual aircraft?

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

Answer: (A)

In this context, a lift is a group of aircraft assigned to a mission, and the way crews verbally refer to each individual plane within that group is by calling it a chalk. Using chalks keeps radio calls concise and unambiguous when many aircraft are moving together—“Chalk one,” “Chalk two,” and so on let everyone know exactly which airplane is being talked about.

So, the term for each individual aircraft within a lift is chalk. This differs from a flight, which denotes the group as a whole; a serial is just an identifying number in records, not the operational label used on the ramp.
