(O) OPERATIONS PROCEDURES — texte MEL :

When dispatching with the automatic locking system or component of the automatic locking system inoperative, the flight deck door must be locked by engaging the deadbolt slides. Sliding the Deadbolt into position locks the cockpit door. In circumstances when the deadbolt is used, always operate both levers of the deadbolt handle on the cockpit side of the door. Splitting the levers will enable the ability to unlock the cockpit door by way of the key. The key is intended for ground use only and is normally used by Maintenance to lock the cockpit door during long periods of inactivity. The Captain will coordinate with the Supernumerary crew regarding the communications to be used prior to Flight Crew unlocking the cockpit door. NOTE: When flight deck door is closed with the flight deck not occupied, make sure the Flight Deck Access System switch is in the OFF position (guard extended).
