3. COCKPIT DOOR.
As seen From the Passenger cabin

4. Flight Deck Door
The flight deck door meets requirements for
resistance to ballistic penetration and
intruder entrance. The door opens into the
passenger cabin. When closed, the door
locks when electrical power is available and
unlocks when electrical power is removed. A
viewing lens in the door allows observation
of the passenger cabin.
The door can be manually opened from the
flight deck by turning the door handle.
The door incorporates a deadbolt with a key
lock on the passenger cabin side.
Rotating both concentric deadbolt levers to
the locked (horizontal) position
prevents the passenger cabin key from
unlocking the door. Rotating only the
forward deadbolt lever to locked allows the
key to unlock the door.

5. The flight deck access system consists of an
emergency access panel, chime module, three
position Door Lock selector, two indicator lights,
and an Access System switch. The emergency
access panel includes a six button keypad for
entering the numeric emergency access code
along with red, amber, and green lights. The red
light illuminates to indicate the door is locked.
When the correct emergency access code is
entered, the amber light illuminates. The green
light illuminates to indicate the door is unlocked.

6. Two indicator lights and a three position Door Lock selector are
located on the aisle stand. Illumination of the amber LOCK FAIL light
indicates the door lock has failed or the Access System switch is in the
OFF position.
The emergency access code is used to gain access to the flight deck
in case of pilot incapacitation. A flight deck chime and illumination of
the amber AUTO UNLK light indicates the correct emergency access
code has been entered and the door is programmed to unlock after a
time delay. Selecting the DENY position on the Door Lock selector
denies entry and prevents further keypad entry for several minutes. To
allow entry, the selector is turned to the UNLKD position which unlocks
the door while held in that position. If the emergency access code is
entered and the pilot takes no action, the door unlocks after expiration
of the time delay. Before the door unlocks, the chime sounds
continuously and the AUTO UNLK light flashes.

7. The door incorporates two pressure
sensors that unlock the decompression
panels in the event pressurization is lost.
The decompression panels have manual
release pins. Pulling the pins frees the
panels allowing egress in the event the
door is jammed.
Decompression panels manually unlocked.
