If the notation shows D-5, what does it indicate?

• A. Five minutes remaining until departure
• B. Five minutes after departure
• C. Five minutes before boarding
• D. Five minutes after arrival

Answer: (A)

Time is shown relative to a specific event, here the departure. D stands for departure, and the minus sign means before that event, with the number indicating how many minutes. So D-5 means five minutes before the departure time. If the plane is scheduled to depart at 10:00, D-5 would be 09:55. This is not after departure or tied to boarding or arrival (which would use different references or a plus sign). The idea is five minutes remaining until departure. If it were D+5, that would mean five minutes after departure.
