Puffy white cloud that often indicates thermal lift.ĬU-NIM - short for Cumulo-Nimbus. Hidden inside sail on double-surface gliders.ĬU - abbreviation for Cumulus. Marked on air sectional charts.ĬOORDINATION - blending of pitch and roll inputs to produce smooth turn.ĬRABBING - angling glider to counteract the effect of wind drift.ĬROSS-CONTROLLING - incorrect weightshift technique that cancels effect of pilots' control inputs.ĬROSSBARS - main glider structural members that run between keel and leading edges. Made up of down tubes and base tube.ĬONTROLLED AIRSPACE - area in which services to pilots are provided by FAA. Excellent for long crosscountry flights.ĬOCOON - soaring harness that encloses and supports pilot from shoulders to toes.ĬONTROL BAR - triangular frame the pilot uses to launch, land and control the glider. Point at which the pilot is suspended from the glider.ĬHORD - distance from leading to trailing edge of a wing.ĬLOUDSTREET - cumulus clouds aligned in 11 streets" by wind. Pilot's hands rest on base tube during flight.īATTEN - formed rib that slips into sail to define airfoil shape.īEAK IN - bungling landing flare so that nose of glider "beaks" against ground.īEST GLIDE SPEED - airspeed at which a glider achieves best glide ratio.īLUE THERMAL - thermal that is not marked by characteristic cumulus cloud.īUNGEE - elasticized cord used to fasten battens and other glider parts.ĬAMBER - cross sectional curvature of an airfoil.ĬARABINER - locking metal link used to attach harness to hang loops.ĬG - abbreviation for Center of Gravity. Precedes final leg.īASE TUBE - tube that forms bottom of glider's triangular control bar.
Determined by dividing a wing's span by its average chord.īACK UP - secondary hang loop used as precaution in case main loop fails during flight.īASE LEG - segment of glider's landing approach. Most common type - Standard Aircraft Approach.ĪSPECT RATIO - measure of how long and narrow a wing is. Designation stamped on hardware to specify that it's of aircraft quality.ĪNGLE OF ATTACK - pitch angle at which the wing meets the air passing over it.ĪPEX - area at the top of the glider's triangular control bar.ĪPPROACH - planned path a glider flies toward landing area. Made up of tubing, cables, plates and bolts.ĪIRFOIL - shaped wing section, designed to provide lift.ĪIRSPEED - speed at which a glider passes through the air.ĪRSA - abbreviation for Airport Radar Service Area.ĪSI - Abbreviation for Airspeed Indicator.ĪLTIMETER - instrument that measures altitude.ĪTTITUDE - orientation of the glider in the pitch, roll or yaw axes.ĪN - abbreviation for Aircraft Nomenclature. AGL - Abbreviation for Above Ground LevelĪIRFRAME - metal frame of a hang glider that supports sail.
