Remain Overnight (RON) for aircraft means what?

• A. The period of time during which a flight attendant is relieved from duty away from his/her domicile for the purpose of legal rest.
• B. A schedule built by the Company utilizing PBS indicating reserve availability periods, assignments, and days off.
• C. When an aircraft is scheduled to remain overnight at a station.
• D. The time spent by a reserve crewmember on stand-by status at an airport designated by the Company.

Answer: (C)

Remain Overnight means the aircraft is scheduled to stay at a particular station overnight rather than returning to its home base. This keeps the plane on site so it can operate the next day’s schedule without lengthy repositioning, often involving overnight parking and readiness checks at that station. The other options describe crew-related situations or schedules, not the aircraft’s status: it's about crew rest away from their domicile, a crew scheduling/public timetable plan, or a reserve crewmember on standby. So the term specifically refers to the aircraft remaining at the station overnight.
