During the Flight Deck Access Panel alarm sequence, the silent period lasts for how many seconds?

• A. 9 seconds
• B. 4 seconds
• C. 6 seconds
• D. 12 seconds

Answer: (B)

The silent period in this alarm sequence is meant to be a deliberate, brief pause between the initial indication and the next step of the sequence. It gives the crew a moment to notice the warning, perform any quick checks, and confirm conditions without prolonging the alert. Because the goal is to move the procedure forward without unnecessary delay, the correct duration is the shortest option among those given. A longer pause would unnecessarily slow the sequence and could disrupt the expected flow of procedures.
