around the body to conserve body heat or to provide
relief from excessive sunlight. Eye protection such as
sunglasses are more than welcome if conditions during
the day are bright, as they often are on good soaring
days.
COMMUNICATION
Communication can be electronic, visual, or audible.
Radios, telephones, and cell phones are electronic
methods. Signal mirrors, flashlight or light beacons at
night, signal fire flames at night, signal smoke during
daylight hours, signal flares, and prominent parachute
canopy displays are visual methods. Shouting and
other noisemaking activities are audible methods but
usually have very limited range.
Coin, cash, or credit cards are often necessary to
operate pay phones. Charged batteries are required to
operate cell phones, two-way radios, and emergency
locator transmitters. Batteries are also necessary to
operate flashlights or position lights on the glider for
signal purposes. A list of useful telephone numbers
aids rapid communication. The aviation transceiver
can be tuned to broadcast and receive on the emergency
frequency 121.5 MHz or any other useable frequency
that will elicit a response. The ELT can be
used to provide a continuous signal on 121.5 MHz.
The parachute canopy and case can be employed to
lay out a prominent marker to aid recognition from
the air by other aircraft. Matches and a combustible
material can provide flame for recognition by night
and provide smoke that may be seen during daylight
hours.
NAVIGATION EQUIPMENT
Aviation charts help to navigate during flight and help
pinpoint the location when an off-airport landing is
made. Sectional charts have the most useful scale for
cross-country soaring flights. Local road maps (with
labeled roads) should be carried in the glider during all
cross-country flights. Local road maps make it much
easier to give directions to the ground crew, allowing
them to arrive as promptly as possible. GPS coordinates
also help the ground crew if they are equipped
with a GPS receiver and appropriate charts and maps.
Detailed GPS maps are commercially available and
make GPS navigation by land easier for the ground
crew.
MEDICAL EQUIPMENT
Compact, commercially made medical or first aid kits
are widely available. These kits routinely include
bandages, medical tape, painkillers and other medicines,
disinfectants, a tourniquet, matches, a knife or
scissors, bug and snake repellent, and other useful
items. Ensure that the kit contains medical items suitable
to the environment in which you are operating.
Stow the kit so it is secure from in-flight turbulence
but is accessible after an emergency landing, even if
injured.
STOWAGE
Stowing equipment properly means securing all equipment
to protect occupants and ensure integrity of all
flight controls and glider system controls. Items carried
aboard must be secure even in the event that
severe in-flight turbulence is encountered. Items must
also remain secured in the event of a hard or off-field
landing. No item carried in the glider should have any
chance of coming loose in flight to interfere with the
flight controls. Stowed objects should be adequately
secured to prevent movement during a hard landing.
OXYGEN SYSTEM
The oxygen system is a life support system during
flights at high altitude. Ensure that all components of
the system are in working condition and that the bottle
has a sufficient charge of aviators’ breathing oxygen.
The oxygen bailout bottle should be in good condition
and in an easy-to-reach position should the need to
abandon the glider at very high altitude arise. The
bailout bottle is most commonly stowed aboard the
8-19
glider when embarking on high-altitude flights in
mountain wave conditions.
PARACHUTE
The parachute should be clean, dry, and be stored in a
cool place when not in use. The parachute must have
been inspected and repacked within the allowable time
frame. For synthetic canopy parachutes this interval is
120 days.
9-1
Glider pilots face a multitude of decisions, starting
with the decision to take to the air. Pilots must determine
if weather conditions are safe, and whether the
conditions will support soaring flight. Gliders, being
powered by gravity, are always sinking through the air.
Therefore, glider pilots must seek air that rises faster
than the sink rate of the glider to enable prolonged
flight. Glider pilots refer to rising air as lift, not to be
confused with the lift created by the wing.
