Which sequence lists the correct chronological order of pre-departure events?

• A. Check-in/report, crew briefing, onboard, boarding
• B. Check-in/report, onboard, crew briefing, boarding
• C. Check-in/report, boarding, crew briefing, onboard
• D. Check-in/report, boarding, onboard, crew briefing

Answer: (A)

The sequence tests understanding of how crew preparation and aircraft readiness unfold before departure. The proper order is to report for duty, then receive the crew briefing, then go onboard to prepare the aircraft, and finally board passengers. Reporting for duty first ensures everyone is accounted for and can participate in the briefing. The briefing then communicates roles, responsibilities, and any specific flight details, which must be reviewed before anyone boards. Once onboard, the crew can perform the necessary preflight and cabin preparations to ensure the aircraft is ready for passengers. Passengers board only after these readiness steps are completed, to maintain safety and efficiency. Other sequences place boarding before the crew briefing or before the aircraft is onboard, which would leave safety procedures and airplane preparations incomplete or uncoordinated.
