• the door opens inside the flight deck and hangs from the ceiling on hinges.
The overhead door is used for emergency egress in combination with the installed
inertial reels. To access these reels:
• rotate the reel stowage lever to the open position
• retrieve the inertial reels from the compartment.
The EICAS advisory message DOOR FD OVHD is displayed if the door is not
closed, latched and locked.
Flight Deck Overhead Door Emergency Egress
If the flight deck overhead door must be used for emergency egress, use the
following procedure:
• open the upper door
• open the inertial reel stowage door (next to door in the flight deck ceiling)
• remove the inertial reel and pull on it to ensure it is securely attached
• throw reel out of hatch (reel stays within safe reach on top of the airplane)
• climb out the door (see following illustration) using the first observer’s
seat (1), the observer’s console (2), the fold-down step in the bulkhead
(3), and the door sill (4)

• lie on stomach, grasp reel in both hands, ease over the side of the airplane
• the inertial reel slowly extends and lowers you to the ground.
CAUTION: Ensure the reel is securely fastened to the airplane.
Passenger Entry Doors
The passenger entry doors are used to enter and exit the airplane, and also serve
as emergency exits. There are no other passenger cabin exits. The eight passenger
entry doors are paired along the airplane fuselage. The doors are identified 1
through 4 left, and 1 through 4 right. The passenger entry doors can be opened or
closed manually from inside or outside of the airplane.

The entry doors are translating, plug–type doors. During opening, the door first
moves inward and upward, then translates outward and forward. Each door is held
in the open position by a gust lock. The gust lock drops into a latch as the door
nears its forward limit of travel. A window in each door allows observation
outside of the airplane.
Each door has a vent panel connected to the door handle. The vent is designed to
prevent pressurization to an unsafe level if the door is not fully closed, latched, and
locked. Forward rotation of the door handle past the latched position closes the
vent. Initial aft door handle rotation opens the vent to equalize cabin and ambient
pressure. At low differential pressure, the door handle can be rotated to allow the
door to open fully. At high differential pressure, the vent can be partially opened;
however, a mechanical interlock prevents door opening until the differential
pressure is reduced. At very high differential pressure, the vent cannot be opened.
Flight Lock
Each door handle is automatically locked when ground speed is greater than 80
knots. The flight lock allows limited door handle rotation sufficient to partially
open the door vent, but prevents door opening. If electrical power is removed or
fails, the flight lock is spring–loaded to the unlocked position.
Emergency System Operation
Emergency evacuation slide/raft and pneumatic door opening systems are
contained in each passenger entry door. Each door system has enough power to
open the door unassisted, even if the airplane is not level because of any landing
gear collapse condition. A bustle in the lower face of the door contains the
slide/raft.
The pneumatic door opening system is armed when the mode select lever is in the
armed position. This engages the door girt bar and arms both the slide/raft and the
pneumatic door opening systems. Once armed, moving the interior door handle to
the open position operates the pneumatic opening actuator. The actuator drives the
door open, and the slide/raft automatically deploys and inflates.
The pneumatic door opening system and the slide/raft are automatically disarmed
when the door is opened from the outside. If the mode select lever is in the armed
position and the door is opened using the exterior door handle, the mode select
lever automatically moves to the disarmed position and the door opens without
slide/raft deployment.
