The girt bar retainers hold the girt bar in a safe configuration
when the escape slide is not armed.
The latch holds the escape slide compartment closed when not
in use.
Escape Slide Pack
The escape slide pack has these parts:
* Escape slide
* Escape slide valise
* Girt
* Girt bar
* Inflation cylinder with pressure gage
* Inflation cable
* Battery.
The valise is a protective cover which holds the slide in the
packed position. The valise opens to deploy the slide.
Tension on the girt and girt bar opens the cover latch and
valise, and deploys the slide. An inflation cable attaches the girt
to the inflation valve.
Tension on the inflation cable opens the inflation valve. When
the inflation valve is open, high pressure air in the inflation
cylinder and the aspirator inflates the escape slide.
The battery provides power for the lighting system.

Purpose
The inflation cylinder provides high pressure air to inflate the
escape slide. The volume and pressure of the air is sufficient to
inflate the escape slide within six seconds.
Functional Description
The inflation cylinder holds a mixture of carbon dioxide and
nitrogen at 3000 psig. An indicator shows the pressure in the
cylinder. A pressure relief valve protects the cylinder from too
much pressure. The relief valve opens at 4500 psig. A fusible
plug protects the inflation cylinder from high temperatures. The
plug opens at a temperature of 174F.
Tension on the inflation cable turns the inflation valve to the
open position. An internal pressure regulator decreases the
pressure to 550 psig. Gas flows through the hose, check valve,
and aspirator nozzle. It then goes into the slide air chambers.
The gas flow through the aspirator nozzle creates a venturi
effect in the aspirator. The flapper valve opens and ambient air
flows through the aspirator to help inflate the slide.
When the pressure inside the slide is a specified value, the
flapper valve closes. Gas continues to flow from the cylinder
into the slide raft. When the slide is at the correct operating
pressure (2.75 psig), a relief valve opens to prevent
overpressurization.
Training Information Point
To make sure that the slide is ready for use, monitor the
pressure indicator at regular intervals as necessary by airline
procedures.
The pressure indicator makes allowance for temperature
changes. The pointer and green band move with pressure
changes. If the pointer is within the green band, the cylinder
pressure is correct for the cylinder temperature.
You must install the safety pin to lock the inflation valve during
removal or installation of the escape slide pack. When you
return the airplane to its usual condition, be sure to remove the
pin from the valve. The slide valise has a pocket for the safety
pin.
WARNING: TO PREVENT ACCIDENTAL INFLATION OF
ESCAPE SLIDE AND POSSIBLE INJURY TO
PERSONNEL, SAFETY PIN MUST BE INSTALLED
WHENEVER SLIDE IS NOT INSTALLED IN THE
AIRPLANE.
CAUTION: PIN MUST BE REMOVED WHEN ESCAPE SLIDE IS
INSTALLED, SO SLIDE WILL BE OPERATIVE IN
EMERGENCY.
To deflate the slide after an inflation test, hold the aspirator
flapper valve open.
