LIFEJACKETS
Lifejackets or life vests are mandatory on airplanes travelling over water
(in which case they consist of a pair of air cells (bladders) that can be
inflated by triggering the release of carbon dioxide gas from a canister -
one canister for each separate cell.
Or the cells can be inflated "orally" that is by blowing into a flexible tube
with a one-way valve to seal the air in the cell
© Allen Peter Diman 5

6. FOR TRAINING PURPOSE ONLY
Malaysian Institute of Aviation Technology
Some of the inflatable life jackets also react with the salt/fresh
water, inflating them.
The latest generation of self triggering inflation devices,
however, respond to water pressure when submerged and
incorporate an actuator known as a "hydrostatic release".
Regardless of whether manually (pull cord) or automatically
triggered, a pin punctures the cartridge/canister and the CO2
gas escapes into the sealed air chamber.
The air chambers are always located over the breast, across the
shoulders and encircling the back of the head. They may be
inflated by either self-contained carbon dioxide cartridges
activated by the pulling of a cord, or blow tubes with a one-
way valve for inflation by exhalation.

EXAMPLE OF CREW LIFEJACKET
Designed specifically for pilots and
aircrew to be worn over flight suits,
the MSV971 is an inflatable flotation
cell integrated into a survival vest.
Providing a full 37 lbs of buoyancy,
the inflatable cell - available in
manual inflation - is comprised of two
independent chambers, separated by a
fully integrated floating baffle system.
This provides for an orally inflated
reserve chamber in the event that the
primary chamber becomes damaged..

8. FOR TRAINING PURPOSE ONLY
Malaysian Institute of Aviation Technology
Each vest is lightweight - approximately 3 lbs unloaded - and contains
specific pocket requirements for stowage of survival items such as rations
or lights. It is made with a Nomex fire resistant cover and mesh for high
durability. As well, each vest is integrated with a lifting harness for over-
water rescue by helicopter, and contains a buddy line and SOLAS
emergency whistle
Key Features:
1. Manual inflatable flotation cell
2. Survival vest contains specific pockets for stowage of survival gear
3. Made with Nomex fire resistant fabric and mesh
4. Dual chamber system for emergency oral inflation in the event of damage
to one chamber
5. Integrated lifting harness
6. Waist and chest adjustment straps
7. Buddy-line and SOLAS whistle

MAINTENANCE OF
LIFEJACKETS
LIFE JACKETS WHICH HAVE
BEEN USED FOR
DEMONSTRATION SHOULD
BE RETURNED AS IF THEY
WERE TIME EXPIRED.
CLEANING IS CARRIED OUT
USING WARM WATER AND
RECOMMENDED SOLVENT.
LEAKS MAY BE DETECTED
BY IMMERSION IN WATER
PRESSURE TESTING IS
CARRIED OUT IAW
MANUFACTURER'S
INSTRUCTIONS WHICH
TYPICALLY WOULD
REQUIRE INFLATION TO A
GIVEN PRESSURE THEN,
AFTER SPECIFIED TIME,
CHECKING THE PRESSURE
HAS NOT FALLEN BEYOND
LIMITS.
THIS IS FOLLOWED BY
SIMILAR TEST INVOLVING A
LONGER INFLATION PERIOD
BEFORE CHECKING ANY
PRESSURE DROP.

INSPECTION FOR CONDITION
WHILST INFLATED THE JACKET IS INSPECTED FOR
DISTORTION AND DAMAGE AND ANY MARKING
NECESSARY TO INDICATE DEFECTS MUST BE MADE
USING WHITE CHALK ONLY.
IF THE LIGHT IS OPERATED BY A DRY CELL, THE
BATTERY MUST BE REPLACED EVERY 6 MONTHS.
MANY ARE POWERED BY A WATER ACTIVATED
CELL & HAVE AN INDEFINITE LIFE PROVIDED NO
ACTIVATION HAS TAKEN PLACE DUE TO INGRESS OF
WATER.

11. FOR TRAINING PURPOSE ONLY
Malaysian Institute of Aviation Technology
A VISUAL MEANS OF CHECKING THIS IS OFTEN
PROVIDED.
THIS TYPE OF CELL IS ELECTRICALLY TESTED BY
CONNECTING A RESISTANCE TESTER ACROSS THE
CELL TERMINALS & OBTAINING A SPECIFIED
READING, E.G 5 MEGAOHMS MIN.
ALL TYPES OF LIGHTS TOGETHER WITH THEIR
CIRCUITS ARE CHECKED FOR CONTINUITY USING A
SLAVE 1 ½ VOLT BATTERY.
CO2 CYLINDERS ARE CHECKED FOR CORRECT
CONTENTS BY WEIGHING AND ARE “LIFED”
USUALLY 10 YEARS

FUNCTIONAL CHECK
AFTER THE MAINTENANCE HAS BEEN COMPLETED THE
JACKET SHOULD BE INSPECTED TO SEE THAT ALL
EQUIPMENT HAS BEEN PROPERLY FITTED & THAT ALL AIR
HAS BEEN EXPELLED.
ON SOME TYPES THIS IS CARRIED OUT BT FITTING A
DEFLATION KEY TO THE MOUTH VALVE; AFTER DEFLATION
THE KEY MUST BE REMOVED.
THE JACKET IS THEN FOLDED IAW MANUFACTURER'S
MANUAL BEFORE PUTTING IT BACK INTO VALISE &
SECURING THE FLAP.
NEXT DUE INSPECTION MUST BE ATTACHED TO THE LIFE
JACKET.

Manufactured from light-weight,
high-visibility polyurethane
proofed nylon fabric.
A range of stowage options
available to suit any situation.

person
All lines must be suitably stowed and
secured to prevent entanglement
during launching/inflation of a life
raft
Mooring Line. A non-rotting mooring
line at least 20 feet in length must be
attached at one end to one end of the
raft, with the remainder of the line
held flaked to the carrying case.
The mooring line must be capable of
keeping the raft, loaded to maximum
rated capacity, attached to a floating
aircraft, and not endanger the raft or
cause the raft to spill occupants if the
aircraft sinks. The line may be
equipped with a mechanical release
linkage.

LIFE RAFT LAUNCHING
EQUIPMENT
A parachute ripcord grip and
retaining pocket must form the
primary inflation control.
The ripcord grip or the attached
static mooring line must be
provided with means for
attachment to the aircraft.
If the ripcord grip is designed to
attach to the aircraft, its strength
may not be less than that of the
static mooring line. The position
of the ripcord grip must be
standardized.
A sea anchor, or anchors, or other
equivalent means must be
provided to maintain the raft, with
rated capacity and canopy
installed, on a substantially
constant heading relative to the
wind and have the ability to
reduce the drift to 2 knots in 17 to
27 knot winds

EMERGENCY INFLATION
Means readily accessible to
occupants of the raft, must be
provided to manually inflate and
maintain chambers at minimum
operating pressure.
Manual inflation valves, with a
non-return opening adequate for
the size and capacity of the
inflation means, must be located
to permit inflation of all
chambers.
The location must take into
consideration occupancy of each
side of reversible raft.
The inflation means and valves
must have provisions to prevent
inadvertent removal and loss
when either stowed or in use.
The color of the liferaft's surfaces,
including the canopy surface,
visible from the air must be an
International Orange-Yellow or
an equivalent high visibility color.
