To activate the Flight Deck Access Panel, press and hold the emergency entry button for ____ seconds.

• A. 5 seconds
• B. 1 second
• C. 3 seconds
• D. 2 seconds

Answer: (C)

Holding the emergency entry button for a short, deliberate duration is the way the system confirms you intend to gain access. The required time is three seconds, which is long enough to prevent accidental activations from a quick touch or jostle, but short enough to still allow prompt entry when truly needed. If you release before three seconds, the panel won’t engage, and there’s no need to hold longer because three seconds is the specified sequence for reliable operation. This timing helps maintain security while ensuring authorized personnel can reach the flight deck when required.
