Launch Site Safety ProceduresLaunch Site Safety Procedures• Never put your fingers inside a tow ring• Never walk in front of the bat• Never walk over a moving rope or one that may move• Never touch a moving rope, or one that may move• Be careful of vehicles maneuvering at the site
Emergency ProceduresEmergency Procedures• The glider launch may be aborted by anyone at the
launch site prior to the glider becoming airborne. Once the glider is airborne, only the Tow Pilot, Glider Pilot, or LCO may stop a launch in progress if they see or are experiencing an immediate and critical hazard to flight.
• The "Stop, Stop, Stop" verbal and visual signal shall be given
Stop Signal• STOP, STOP,STOP• Raise both arms with palms facing forward
and yell “Stop, Stop, Stop”
• Signaler will raise signal bat directly overhead in a vertical position so it is visible to the auto tow observer
Emergency ProceduresEmergency Procedures
Premature Launch• In the event of a premature launch, the glider
pilot shall pull the release immediately
Emergency ProceduresEmergency Procedures
Premature launches occur rarely … but they do happen
An Aborted Auto Tow LaunchIf there is any possibility that the glider may overrun the rope on anaborted auto launch, the pilot shall immediately:
• Pull the release and • Maneuver the glider to the side so as to
provide separation from the rope
Emergency ProceduresEmergency Procedures
Launch FailureLaunch FailureAt or Below 200 Feet AGL• The glider pilot should attempt to land straight
ahead making minor deviations to avoid obstacles• If a straight ahead landing is not possible, turns up
to 90 degrees may be executed at altitudes above 100 feet AGL
G P A S
Between 200 - 500 Feet AGL• In the event of a rope break or premature release
between 200 & 500 feet AGL, the glider pilot should attempt to land straight ahead, using spoilers and forward slipping to eliminate excess altitude
• If the glider pilot is unable to land straight ahead because of insufficient runway, a 180 degree turn to a downwind landing or a landing on an alternate runway shall be executed
• A minimum airspeed of 50 mph should be flown on a downwind landing attempt

Launch FailureLaunch Failure• In the event of a rope break or premature
release above 500 feet AGL, a modified circuit with an abbreviated downwind leg followed by an into-wind landing is the preferred procedure
G P A S
• If the auto tow launch vehicle experiences a power failure, a gradual loss of airspeed will be felt in the glider
• This situation will require a premature release by the glider pilot
• If the auto launch vehicle is able, it will clear the runway – but - be prepared for the vehicle to be disabled and stranded on the runway
Launch Vehicle FailureLaunch Vehicle Failure

Glider Release FailureGlider Release Failure
• The pilot shall over fly the auto launch vehicle and attempt to generate a back release
• The auto launch observer shall activate the release at the launch vehicle once the glider has back released
Off-field Landing ProcedureOff-field Landing Procedure
• The decision to land should always be made while sufficient altitude remains to fly a standard pattern
• The choice of a field should be made while ample altitude is available. The glider pilot should never wait until the last moment to select a field and be forced to make a straight-in approach
• Once the off-field landing has been successfully completed, the pilot should remain with the glider, and attempt to contact the launch site by radio
