Passenger Door 3
When the door mode select lever is in AUTOMATIC position and the door
operating handle is rotated 180 degrees, the door begins to open and the power
assist opening system activates.
The flight attendant must release the door operating handle and continue to assist
the door opening motion by using the assist handles on the door and on the door
surround panel until the door is in the full open and latched position. The
door-mounted escape slide deploys and inflates. An off-wing deployment
indicator is visible to the flight attendant at door 3 when the off-wing escape slide
is properly deployed.
If the ramp/slide does not open automatically, pulling the manual inflation handle
inflates it manually.
If door 3 is used during a ditching situation, placing the door mode select lever in
MANUAL allows the door to be opened without deploying the ramp slide.

Upper Deck Doors
Upper deck doors are used for emergency evacuation only. The escape slides
cannot be used as rafts.
With the door mode select lever in AUTOMATIC position, lifting the door
operating handle acutates the emergency power system for the door, moving the
door up and out to full-open position. The escape slide deploys and inflates as the
door opens.
A gas bottle powers each upper deck door opening mechanism. A pressure gage
is located above each upper deck door for checking bottle pressure.
A green push-to-test battery OK light is located above each upper deck door.
An automatic lock activates in flight to lock the upper deck door operating handles
to prevent inadvertent operation. If the automatic lock fails to activate after
takeoff, it is possible to open an upper deck door when cabin differential pressure
is low.
Flight Deck Overhead Hatch
The flight deck overhead hatch located just aft of the overhead panels can be
opened from either inside or outside the airplane.
The hatch is opened from inside the airplane by rotating the interior handle. The
hatch is opened from the outside by pressing the release trigger which allows the
exterior handle to spring out from its recessed position. Rotating the handle then
unlocks the hatch.
