made of nonslip, nonmarking, jet-fuel-resistant
rubber. The steel box toe is constructed of cold-
rolled carbon steel to provide a safety margin
through greater compression resistance. The boot
is designed for use by all aircrew members.
The boot is fitted to the aircrew member
and normally corresponds to his regular shoe
The aircrew member is responsible for main-
tenance of the boot. Maintenance is limited
to cleaning and polishing. Polish used for
everyday care of shoes is acceptable. There are
no authorized repairs, as the sole and heel should
outwear the upper boot. Broken or worn laces
may be replaced.
SV-2 SURVIVAL VEST
The SV-2B survival vest provides maximum
useful storage for survival equipment, consistent
with minimal bulk and weight. In addition, the
survival vest provides for integration of a life
preserver, anti-g coveralls, and the chest-mounted
oxygen regulator. It does not interfere with use
of either the regular or integrated-type parachute
harness. The SV-2B vest is the latest authorized
configuration for this series of survival vest.
The SV-2B survival vest is constructed basi-
cally of nylon cloth. An adjustable harness,
leg straps, and an entrance slide fastener provide
a means of fitting and securing the vest to the
aircrew member. Elastic straps on the rear allow
greater comfort and mobility of the wearer.
Pockets are provided for stowage of survival items
(fig. 4-4). When required, the chest-mounted
oxygen regulator is located inside a pocket secured
to the vest by means of hook and pile tape.
The basic SV-2B survival vest is designed to
fit chest sizes from 40 to 48 inches. By changing
the elastic straps on the rear, the vest may be
adapted to a wider size range. To fit an SV-2B
properly, have the aircrew member wear all his
normal flight gear, including the MA-2 torso
harness, if used. Put the SV-2B vest on as if it
were a jacket. Pass the leg straps through the
crotch and attach the snap hooks. Adjust the leg
and shoulder straps so that they are snug and the
bottom of the vest is just above the hips. Examine
the SV-2B for proper fit. If it is too loose, the
elastic straps must be shortened. If it is too tight,
you must lengthen the elastic straps. The pro-
cedures for this adjustment, as well as main-
tenance, calendar inspections, and cleaning,
are covered in-depth in the Aircrew Personal
Protective Equipment Manual, N A V A I R
Antiexposure assemblies are composed of
several garments that protect the aircrew member
in the event of immersion. Constant wear
assemblies provide additional protection from
cold weather. The constant wear assemblies
consist of a waterproof outer garment worn over
a ventilation liner and/or cold weather underwear.
The quick-donning antiexposure suit is carried
in the aircraft, and donned only in case of
emergency. It consists of a waterproof outer
garment equipped with permanently attached
boots and wrist and neck seals. An inflatable hood
and antiexposure mittens are stowed in the
pockets. In case of emergency, the assembly is
donned over the regular flight clothing.
Either continuous-wear or quick-donning
antiexposure suits, as appropriate, are provided
for flight personnel and passengers when there is
a significant risk of crashing in the water, and
when any of the following conditions prevail:
1. The water temperature is 50°F or below.
2. The outside air temperature (OAT) is 32°F
(wind chill factor corrected) or below.
If the water temperature is between 50° and
60°F, the commanding officer of the unit
concerned considers the following search and
rescue (SAR) factors:
1. The maximum probable rescue time. This
should be a function of mission distance, SAR
equipment, and SAR location.
2. The lowest temperatures that will occur in
the mission area during the time period of the
3. Then by using table 4-1, he determines
whether antiexposure suits are required.
