In a night seat swap procedure, what is the correct sequence after coordinating with maintenance?

• A. Complete second half of exterior inspection
• B. Complete first half of sortie through Before Leaving Aircraft checklist as normal; Change places; reconfirm ISS & seat pins; Conduct second half of BEFORE EXTERIOR INSPECTION
• C. Reconfirm ISS only, then swap seats
• D. Perform exterior inspection only

Answer: (B)

In this night seat swap, safety hinges on keeping the checklist flow intact while the seat is moved. The best sequence splits the exterior inspection around the seat exchange and rechecks critical items afterward. Start by finishing the portion of the Before Leaving Aircraft checklist that you can do in the current position, then swap seats, then reverify the Integrated/Seat system and make sure the seat pins are correctly installed and secured. After that swap, complete the remaining portion of the exterior inspection. This approach ensures nothing is skipped and any issues introduced by moving the seat are caught—especially important at night when visibility is limited and critical systems must be confirmed as functioning.
