Description and Operation
Emer.10.6
CAUTION: When operating with cabin differential pressure of less
than 1psi, crew should caution cabin attendants to ensure that
unauthorized personnel remain clear of doors.
Procedures which may result in prolonged periods of operation at low differential
pressure are:
• EMERGENCY DESCENT
• SMOKE/FUMES REMOVAL
• OUTFLOW VALVE CONTROL - UNPRESSURIZED FLIGHT
• CABIN SMOKE
•EVACUATION
NOTE: Immediately following inadvertent discharge of a cabin door
pneumatic bottle, reset door control handle from emergency
(pneumatic) to neutral position. This locks door in closed position
until ready for subsequent operation.
Evacuation Slide/Raft
An inflatable evacuation slide/raft (combination escape slide and life raft) is
installed in a slide stowage container, mounted on the inside of:
• Every cabin door on passenger aircraft.
Opening the door will automatically inflate and deploy the slide when the arming
lever adjacent to the door is in the SLIDE ARMED position. On passenger
aircraft, if a door (other than overwing) becomes jammed closed, the slide/raft can
be moved to a usable door for deployment and use as a raft.
A manual inflation handle is installed in the slide/raft assembly and becomes
visible when the slide is deployed. If the automatic inflation mechanism
malfunctions, the manual handle must be pulled to inflate the slide/raft.
The cabin doors are equipped with double-track slide/rafts (optional) so that two
persons can exit the aircraft simultaneously.
The overwing slide/rafts are fitted with integral ramps and deploy over the leading
edge of the wing, outboard of the engine pylon. When the overwing slide/rafts are
deployed and ready for use, slide position indicators will be visible on the upper
end of the slide/rafts.
Each slide/raft and ramp is equipped with self-powered, battery operated electric
lights as an integral part of the slide/raft and ramp. The lights illuminate the
evacuation route from the cargo compartment to the ground or water.
