that a certified rigger repack it within the preceding 120
days. The packing date information is usually found on
a card contained in a small pocket on the body of the
parachute.
14 CFR part 91 also requires that the pilot in command
(PIC) use supplemental oxygen for flights more than
30 minutes in duration above 12,500 feet, and at all
times during a flight above 14,000 feet. If supplemental
oxygen is used, the system should be checked for
flow and availability.
The glider pilot should carry water on every flight to
prevent dehydration. The effects of dehydration on a
pilot’s performance are subtle, but can be dangerous
and are especially a factor in warmer climates.
PRELAUNCH CHECKLIST
Adjustments to the pilot or passenger seats, as well as
the pedals, should be made prior to buckling in. At this
point, especially if the glider has just been assembled,
it is appropriate to do a positive control check with the
help of one crewmember. While the pilot moves the
control stick, the crewmember alternately holds each
aileron and the elevator to provide resistance. This also
applies to the spoilers and flaps. This ensures that the
control connections are correct and secure. If the stick
moves freely while the control surfaces are being
restricted, the connections are not secure, and the
glider is not airworthy. [Figure 6-9]
If the GFM/POH does not provide a specific prelaunch
checklist, then a good generic checklist is ABCCCDD,
which stands for:
A—Altimeter set to correct elevation.
B—Seat belts and shoulder harnesses fastened
and tightened.
C—Controls checked for full and free movement.
C—Cable or towrope properly connected to the
correct hook.
C—Canopy closed, locked, and checked.
D—Dive brakes closed and locked.
D—Direction of wind checked and emergency
plan reviewed.

• Begin by assessing the overall condition of
the fiberglass or fabric.
• Be alert for signs of damage or excessive
wear.
• Check that the canopy is clean and free from
damage.
• Verify the interior wing and control connections
are safe and secure.
• If a battery is used, ensure that it is charged,
and safely fastened in the proper spot.
• Check that seat harnesses are free from excessive
wear.
• To prevent it from inadvertently interfering
with the controls, buckle and tighten any harness
that will not be used.
• Test the tow hook to make sure it is operating
correctly.
• Inspect top, bottom, and leading edge of
wings, making sure they are free from excess
dirt, bugs, and damage.
• Inspect spoilers/dive brakes for mechanical
damage. They should be clear of obstructions.
• Inspect the wingtip and wingtip skid or wheel
for general condition.
• Inspect ailerons for freedom of movement,
the condition of hinges and connections, and
the condition of the gap seal.
• Check the condition of flaps for freedom from
damage and appropriate range of motion.
• Inspect the general condition of the empennage.
• Check static ports, pitot tube, total energy
probe to ensure they are free from obstruction.
• Check top, bottom, and leading edge of
tailplane for freedom of bugs, dirt, and damage.
• Check the landing gear for signs of damage or
excessive wear. The brake pads should be
checked if they are visible, otherwise the
brakes can be checked by pulling the glider
forward and applying the brakes. It should be
noted that the landing gear is frequently a
problem area for gliders used in training.
• Check elevator and trim tab for condition of
connections, freedom of movement, and condition
of gap seal.
• Check rudder freedom of movement and condition
of connections.

AEROTOW LAUNCH SIGNALS
Launching a non-powered glider requires the use
of visual signals for communication and coordination
between the glider pilot, towpilot, and launch
crewmembers. If the aircraft and launch
crewmembers are equipped with compatible
radios, communication is enhanced over hand signals.
Aerotow launch signals consist of pre-launch
