in the flight deck. The inset decompression panel is hinged along the left hand
side, allowing it to swing open from right to left. The panel uses a mechanical
decompression latch that senses the onset of a rapid decompression, thereby
allowing it to open. The decompression latch contains features that make it tamper
and ballistic resistant from the passenger cabin side. In the event of a passenger
cabin decompression, the entire flight deck door is allowed to open permitting
flight deck air to vent into the passenger cabin.
The decompression panel also features an escape mechanism that allows the flight
crew to open it should the door become jammed. This feature allows for egress
from the flight deck to the passenger cabin. The escape mechanism is integrated
into the decompression latch allowing the flight crew to manually trigger the latch
to open the decompression panel.
The flight deck access system incorporates a check to verify the flight deck door
is properly closed and locked. Activation of the EICAS advisory message FD
DOOR OPEN indicates the door lock pin is seated while the door sensor is
indicating the door is open.
The pull-handle design on the passenger side of the door has no key, is not
physically part of the latch, and is designed to limit the amount of pulling force
that can be applied to the door. If this load is exceeded, the handle will separate
from the flight deck door however the door will remain closed and locked.

Flight Deck Access System
The flight deck access system consists of a flight deck access keypad, a flight deck
door access selector, a flight deck door power switch, and EICAS messages.
The flight deck access keypad includes a six button keypad (for entering the door
chime and emergency access codes) along with red, amber, and green LED 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.
Note: The red light will also be illuminated when the FD DOOR POWER switch
is OFF. In this condition, the door is unlocked when closed.
A three position rotary door access selector is located on the aft aisle stand. This
selector is used to allow or deny access to the flight deck. The EICAS advisory
message FD DOOR LOCK FAIL indicates the door lock has failed or the door
power switch is in the OFF position.
Pressing the 1 and then ENT keys on the flight deck access keypad will sound the
flight deck chime and set the EICAS COMM message FD DOOR CALL to be
displayed. The door remains locked unless pilot action is taken.
The emergency access code is used to gain access to the flight deck in case of pilot
incapacitation. Activation of the EICAS warning message FD DOOR AUTO
UNLOCK, the master warning lights, and master warning siren indicate 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 access selector
denies entry and prevents further keypad entry for several minutes. During an
emergency access request, the UNLKD position on the door access selector is
inhibited. To allow entry, the selector must first be turned to the DENY position
and then to the UNLKD position which will unlock the door while held in that
position. Or, if the pilot takes no action during the emergency access request, the
door unlocks after expiration of the time delay.
Dead Bolt Lock
The door incorporates a deadbolt with keyed access from the cabin. The keyed
deadbolt is primarily used to secure the flight deck when power is not available to
the locking system. The locking bolt will retract and engage by the key and/or
flight deck knob only. The deadbolt is placarded, "CAUTION FOR GROUND
USE ONLY".
The deadbolt has a lockout feature in the flight deck so that an intruder with the
key would not be able to unlock the door. The knob clearly indicates the status of
the lock whether it is unlocked, has been locked with a key from the passenger
cabin, or the passenger side key function has been locked out from the flight deck.
