blades be placed in a particular blade pitch position. If
the propeller blades can not be properly adjusted, then
the propeller will not deliver enough torque to turn the
engine over. The result is a failure to obtain an airdriven
engine start.
SELF-LAUNCH GLIDER ELECTRICAL SYSTEM
MALFUNCTIONS
An electrical system failure in a self-launch glider may
make it impossible to control the propeller pitch if the
propeller is electrically controlled. It may also result in
the inability to deploy a pod engine successfully for an
air re-start attempt. Self-launch gliders that require a
functioning electric starter for an air re-start will be
unable to resume flight under power. If an airport is
within gliding range, an on-airport precautionary landing
can be made. If there is no airport within gliding
range and the flight can be safely continued without
electrical power, the pilot may be able to soar to the
vicinity of an airport and land safely. If no airport is
within gliding range and flight cannot be sustained
without power, an emergency off-airport landing has
to be made.
Some self-launch gliders are occasionally used for
night flight, cruising under power and operating the
necessary aeronautical lighting. If an electrical system
failure occurs during night operations, pilots of nearby
aircraft are not able to see the self-launch glider due to
the extinguished position lights. Inside the cockpit, it is
difficult or impossible to see the flight instruments or
electrical circuit breakers. Carry a flashlight for such an
emergency. Check the circuit breakers and reset any
breaker that has overloaded unless the smell of smoke is
present or any other indication of an overheating circuit.
[Figure 8-8] Head directly for the nearest airport and
prepare for a precautionary landing there. The aviation
transceiver installed in the instrument panel may not
function if electrical failure is total, so it is a good idea
to have a portable battery-operated aviation two-way
radio aboard for use in such an emergency.
IN-FLIGHT FIRE
In-flight fires are the most serious emergencies a pilot
can encounter. If a fire has ignited, or if there is a smell
of smoke or any similar smell, do everything possible
to reduce the possibilities that the fire spreads and land
as soon as possible. The self-launch glider GFM/POH
is the authoritative source for emergency response to
suspected in-flight fire. The necessary procedures are.
• reduce throttle to idle;
• shut off fuel valves;
• shut off engine ignition;
• land immediately and stop as quickly as
possible; and
• evacuate the self-launch glider immediately.
After landing, get far away from the glider. Keep
onlookers away from the glider as well. The principal
danger after evacuating the glider is that the fuel will
ignite and explode, with the potential to injure personnel
at considerable distance from the glider.
EMERGENCY EQUIPMENT
AND SURVIVAL GEAR
Emergency equipment and survival gear is essential
for safety of flight for all soaring flights.

SURVIVAL GEAR ITEM CHECKLISTS
Checklists help to assemble the necessary equipment in
an orderly manner. The essentials for survival include
reliable and usable supplies of water, food, and air or
oxygen. Maintenance of an acceptable body temperature,
which is difficult to manage in extreme cold or extreme
heat, is also important. Blankets and appropriate seasonal
clothing help to ensure safe body temperatures.
FOOD AND WATER
An adequate supply of water and food (high-energy
foods such as energy bars, granolas, and dried fruits
are usually best) are of utmost importance during
cross-country flight. Water from ballast tanks can be
used in an emergency if free of contaminants such as
antifreeze. Water and food should be available and
reachable during the entire flight. Pilot relief for urination
should also be easy to access and use.
CLOTHING
Pilots also need seasonal clothing that is appropriate to
the local environment, including hat or cap, shirts,
sweaters, pants, socks, walking shoes, space blanket,
gloves or mittens. Layered clothing provides flexibility
to meet the demands of the environment. Desert
areas may be very hot in the day and very cold at night.
Prolonged exposure to either condition can be debilitating.
Layered clothing traps air between layers,
increasing heat retention. The parachute canopy can be
used as an effective layered garment when wrapped
