Il y a un code d'accès en cas d’incapacité des deux pilotes. sauf si le sélecteur est sur "lock" semble-t-il , tempo de 5 minutes au moins (Le cas de germanwings, le co-pilote a réenclenché "lock" plusieurs fois.).
Si le PNC ou autre fait le code d'ouverture de l'exterieur, un buzzer prévient les pilotes pendant 30 s.
Si il n'y a pas d'action "lock" dans le cockpit, la porte peut être ouverte de l'exterieur au bout de 30 s pendant 5 s.
GREEN light ONhe door has been unlocked either by a flight crew action, or automatically (during 5 s) when no flight crew action is performed during the delay following an emergency access request. The door can be pushed open.
GREEN light flashesAn emergency request to enter the cockpit has been made; the buzzer will sound continuously in the cockpit, but no action has yet been taken by the flight crew.
RED light ON The flight crew has denied access, and the door remains locked.
WHITE light ON The light comes on each time the cabin crew presses a key on the keypad.
Digital Keypad
The keypad is used to sound the buzzer in the cockpit for 1 to 9 s (3 s by default), by entering a zero to seven-digit code, as programmed by the airline, followed by the '#' key. It is also used to enter the two to seven-digit emergency code, followed by the '#' key, when the flight crew does not respond.
Note: During the test performed by the cockpit door control unit, the CDLS keypad remains operational, and the CDLS operates as follows:
The control unit will store access codes that are entered, and the LOCKED/UNLOCKED DOOR INDICATOR (RED/GREEN LEDs) of the keypad will remain on, as long as the test is running.
‐ If the correct access code is entered on the keypad, the buzzer will not sound, until the test is completed.
‐ If the emergency access code is entered, the door will unlock. The cockpit buzzer and the LOCKED/UNLOCKED DOOR INDICATOR will be inoperative.
Note: 1. If the LOCK position has not been used by the pilot, for at least 5 to 20 min, the cabin crew is able to request emergency access to open the cockpit door.
2. The UNLOCK position overrides and resets any previous selection.
3. In case of an electrical supply failure, the cockpit door is automatically unlocked,
but remains closed.
(2) COCKPIT DOOR Fault Open indicator
OPEN light ON : The door is not closed, or not locked.
OPEN light : The cabin crew has started an emergency access procedure. If there flashes is no reaction from the flight crew, the door will unlock at the end of the
adjustable time delay (15 to 120 s).FAULT : This light comes on when a system failure has been identified (Example : Latch, pressure sensors, control unit).
The inoperative item can be identified by checking the strike and pressure sensor status lights on the CKPT DOOR CONT panel.
il sert donc à quelque chose le code secret ...??
