Which term describes a schedule indicating reserve availability periods, assignments, and days off?

• A. Remain Overnight (RON) - aircraft
• B. Preflight Inspection
• C. Tail Wind
• D. Reserve Line

Answer: (D)

This question tests knowledge of airline crew scheduling terms. A reserve line is the schedule that shows when a crew member must be available as a reserve, the assignments they may receive if called, and the days off. It sets up on-call blocks so a crew can be tapped to cover gaps without having a fixed trip every day. When not on reserve, a crew member would have a regular line, while the reserve line provides flexibility for last‑minute needs. The other terms don’t describe a crew schedule: Remain Overnight refers to an aircraft staying somewhere overnight, Preflight Inspection is the safety check done before a flight, and Tail Wind describes wind direction and speed relative to the flight path.
