In the standard turn timeline, when does the MCD close?

• A. 5 minutes prior to departure
• B. 10 minutes prior
• C. 15 minutes prior
• D. 20 minutes prior

Answer: (A)

The timing tested is about how the standard turn sequence sequences safety and security checks just before pushback. Closing the MCD five minutes before departure gives just enough margin for the final door status verification and quick safety checks while still keeping the window tight enough to avoid unnecessary re-openings for late boarding or servicing. If it closed earlier, there’d be a risk the door would need to be reopened for late tasks, wasting time. If it closed later, there wouldn’t be enough room to confirm the door is securely sealed and to complete the final pre-taxi steps, which could delay pushback. So, five minutes prior to departure is the designated time.
