The lower panel is hinged at the top and will swing like a ‘cat flap’. Caution: The panel could strike personnel on the jump-seat. The top panel is hinged at the bottom of the panel and will fall forwards into the flight deck. Should the flight deck lose pressurisation, the rush of cabin air into the flight deck will activate the pressure switches and release the two panels. Should the cabin lose pressurisation, there is sufficient space for air in the flight deck to escape around the doorframe into the cabin. Two decompression/egress panels are installed in the door with pressure switches located at the top and bottom of the door. Decompression Panels/Emergency Egress Panels If the door is not opened during this 5-second period, the process will have to be repeated as the door will automatically lock. The green LED will illuminate and the AUTO UNLK light will extinguish. At the end of the timing cycle and after the continuous tone has sounded, the door solenoid will disengage to unlock the door for 5 seconds. After two thirds of the programmed timing, a continuous tone will be activated and the AUTO UNLK light will flash. After approximately one third of the programmed timing, the double tone will sound again. A second door unlock timer is activated and the AUTO UNLK light on the flight deck will illuminate steady and an initial double tone will be heard on the flight deck. In the event of pilot incapacitation, a different door code is entered on the Remote Access Panel. The lock out timer is reset after the timer has finished or when the FLT DK DOOR switch is moved to UNLKD. A pre-programmed lock out timer will start which illuminates a red LED and disables the Remote Access Panel. Should access to the flight deck need to be denied, the FLT DK DOOR switch should be positioned to DENY and released to AUTO. As the door weighs approximately 36 Kg, it should be closed firmly and pushed closed to ensure positive engagement of the door latch. If a decompression panel inadvertently opens, immediately close it and reset the latch. AUTO UNLK - illuminates when timer operation is activated by either deny entry or incapacitation.Ĭaution: Do not slam the door shut excessively as the force can exceed the limits of the pressure relief latches and cause inadvertent opening of the decompression panels described later.LOCK FAIL - illuminates when lock solenoid is not electrically powered.Located next to the FLT DK DOOR switch are two lights: Turning the door handle on the flight deck side only can also open the door. The amber LED will extinguish and the green LED will then illuminate on the access panel, indicating door unlocked. Having identified the person making the request, the door is unlocked in the flight deck by pushing in, rotating and holding the spring loaded FLT DK DOOR switch from AUTO to UNLKD. After the code has been entered, an amber LED will illuminate on the access panel and a buzzer will sound on the flight deck. Normal EntryĪ request to enter the flight deck is made by entering a code on the Remote Access Panel located on the cabin side of the door frame. A key is provided to unlock the dead-bolt from the passenger cabin side only. An additional mechanical dead-bolt lock is provided for MEL relief and to secure the flight deck when the aircraft is left unattended for an extended period of time. A lock timer is also provided for emergency access in the event of pilot incapacitation. Should the electrical power or locking system fail, the door will automatically unlock. The C&D Aerospace door is normally locked and unlocked from the flight deck using an electronic locking system whenever electrical power is available on the aircraft.
