Airplane General - Doors & Windows

The airplane has six passenger entry doors, two emergency doors, one flight deck door (the flight deck/passenger cabin entry), and three cargo doors. It also has electrical equipment and forward equipment bay access doors.

The flight deck number two windows, one on the left and one on the right, can be opened by the flight crew.

An EICAS message is displayed when a passenger entry door, emergency door, cargo door or access door is not closed and latched, and locked.

Flight Deck Door

Flight Deck Number Two Windows

The flight deck number two windows can be opened on the ground or in flight. The flight deck number two windows can be used for emergency evacuation. The window lock lever locks or unlocks the window. Rotating the window Hand Crank opens and closes the window.

Note: It is possible to rotate the window lever forward to the locked position with the window not closed. In this position the WINDOW NOT CLOSED decal remains partially visible

A WINDOW NOT CLOSED placard is visible when the window is open.

To properly lock the window, it must first be fully closed by rotating the Hand Crank, clockwise for the Captains window and counter clockwise for the First Officers. As the window approaches the full closed position, required force on the Hand Crank noticeably increases, but rotation must continue until reaching the limits of travel. When the window is fully closed, rotate the lock lever forward to the locked position and assure the WINDOW NOT CLOSED decal on the window silt is hidden from view. When attempting to close the window, the lock lever must first be in the unlocked position to permit window travel to the full closed position.

The windows can be opened or closed in flight with minor flight deck consequences if the airplane is unpressurised. Because the force required to move the crank increases with airspeed, it is recommended not to exceed VREF 30 + 80 with a window open. It may not be possible to open or close the window at speeds above 250 knots. With the window open, voice, interphone, and radio audio cannot be heard due to high noise levels. Prior communications arrangements with the controlling agency should be established before opening the window. The design provides an area of relatively calm air over the open window. Forward visibility can be maintained by looking out of the open window.

Flight Deck Window Emergency Egress

If the flight deck number two windows must be used for emergency evacuation, exit in accordance with the following illustration [omitted].

CAUTION: Ensure the rope is securely fastened to the airplane.

Passenger Entry/Service Doors

The six passenger entry/service doors are use to enter and exit the airplane and also serve as emergency exits. The passenger entry doors are paired along the airplane fuselage. The doors can be opened or closed manually from inside or outside the airplane.

The forward Left and centre left doors (L1 and L2) can be raised or lowered electrically through the electrical control panel located within the external door handle recesses and on the forward and mid attendant panels. The doors must be locked or unlocked manually and electrical power is available only when the respective door handle is in the UP position.

The entry doors are plug-type doors. During opening, the door first move inward, then upward into the ceiling. The weight of the door and the slide is counterbalanced so that very little effort is required for operation. The door is held open by a latch in the upper part of the door frame. In order to close the door it must intially be raised slightly, then push and hold Uplatch Release Button, then lower door approximately 2 inches (5 centimetres). Release button and continue to lower door.

WARNING: Stand clear of the door handle as the handle may move as the door is lowered.

Use the interior or exterior handle to lock the door.

An escape slide/raft is contained in a bustle on the lower inboard face of the door. A Wide Angle Viewer is used for observing the outside of the airplane.

The ENTRY DOORS light illuminates and the EICAS advisory message L AFT, L CTR, L FWD, R AFT, R CTR or R FWD ENT DOOR displays when a passenger entry door is not closed and latched and locked. If two doors on the same side of the airplane are not closed and latched and locked, the EICAS advisory message L/R ENTRY DOORS displays.

Passenger Entry Door and Slide Operation

A manual inflation handle can be pulled if the slide has not automatically inflated.

The emergency door opening system and the slide are automatically disarmed when the door is opened from the outside. If the arming lever is in the ARMED position and the door is opened using the exterior door handle, the arming lever automatically moves to DISARMED and the door opens without slide deployment.

The passenger door evacuation slides are also configured as rafts.

Emergency Doors

An emergency door is located aft of the wing on each side of the airplane. The emergency door is only used as an emergency exit. A slide bustle in the lower face of the door contains an evacuation slide. A window in the door allows observation outside of the airplane.

The emergency door is a plug-type door and is hinged on the bottom. Pulling the door-operating handle up lifts the door inward and upward and opens a pressure relief door. The door can then be pushed out through the door frame and the slide automatically deploys and inflates.

A manual inflation handle can be pulled if the slide has not automatically inflated.

The EMER DOORS light illuminates and the EICAS advisory message L/R EMER DOOR displays when an emergency door is not closed and latched and locked. If both doors are not closed and latched and locked, the EICAS advisory message EMER DOORS displays.

The emergency door evacuation slide's are not configured as rafts, however they may be used as auxiliary flotation devices.

Cargo Doors

There are two Cargo Doors; one forward and one aft. Both doors are located on the right side of the airplane. The cargo doors open upward and outward.

A bulk cargo door is located in the aft left side of the airplane. The aft cargo compartment and the bulk cargo compartment are separated by a removable net. The bulk cargo compartment has no conveying equipment. Bulk cargo is loaded and unloaded manually, and is held by cargo nets.

Both forward and aft cargo doors are normally operated electrically from an exterior or interior fuselage-mounted control panel located with each door. Forward cargo door locking is accomplished manually. If necessary, the forward and aft cargo doors may be operated manually.

Access Doors

Access to the forward equipment bay and the electronics bay is provided in the forward lower fuselage. If either door is not closed and locked, the ACCESS DOORS light on the overhead panel illuminates and the EICAS advisory message FWD ACCESS DOOR or E/E ACCESS DOOR displays. If both doors are open, the advisory message ACCESS DOORS appears.

Flight Deck Seats

The pilot seats:

• Recline
• Adjust vertically
• Adjust forward and aft
• Adjust for thigh support
• Adjust for the lumbar region of the back

The seats also have:

• Adjustable armrests
• Crotch straps
• Inertial-reel shoulder harnesses with manual locks
• Lap belts
• Adjustable headrests

The seats move outboard during the last four inches of travel. Manual controls provide forward, aft, and vertical adjustment.

Lumbar and thigh pad support can be adjusted using the adjustment hand wheels. Armrest pitch can be adjusted using the control knob under the armrest. The armrests can be stowed vertically for easier seat access.

Adjust the seat to obtain the optimum eye position as shown on the above illustration:

1. Adjust the seat to the upright position; sitting up straight; looking straight ahead.
2. The control column must be in the neutral position.
3. Adjust the seat until:
   • the top of the glareshield appears as the edge of a plan and
   • the bottom the HSI is visible over the control column
