Doors and Windows
The airplane has two passenger entry doors, one cabin door (the flight
deck/passenger cabin entry), two service doors and two cargo doors. There is also
a center electrical and electronic (E/E) equipment access door and an equipment
compartment access door on the bottom of the airplane.
The flight deck number two windows, one on the left and one on the right, can be
opened by the flight crew.
CAUTION: Do not operate the entry or service doors with winds at the
door of more than 40 knots. Do not keep the entry or service
doors open when wind gusts are more than 65 knots. Strong
winds can cause damage to the structure of the airplane.
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.
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.
Two indicator lights and a three position Door Lock selector are located on the aft
electronic panel. Illumination of the amber LOCK FAIL light indicates the door
lock has failed or the Access System switch is in the OFF position.
