A collection of common terms and definitions used in Paragliding
Accelerator – See “Speed Bar”
Accordion Fold – A method of folding a paraglider with the intent of minimizing the amount of creasing on the mylar on the leading edge.
Active Piloting – A method used by paragliders of maintaining wing loading, via brake pressure or weight shifting, to prevent collapses or folds.
AGL (Above Ground Level) – A pilot’s altitude measured with respect to the underlying ground surface.
Airfoil – The curved shape of a wing which is designed to create lift.
Air Mass – A large body of air, usually 1,600 kilometers or more across, that is characterized by homogenous physical properties at any given altitude.
Air Pressure – The force exerted by the weight of a column of air at a given point over a certain surface area.
Airspeed – The speed of an aircraft relative to its surrounding air mass. If a pilot is piloting a paraglider with a trim speed is 20 km/h, into a 20 km/h headwind, the pilot’s airspeed is still 20 km/h.
Airspeed Indicator – An instrument often used by paraglider pilots to measure their airspeed. This can be important when flying a glider at an optimal glide ratio, or maximum speed.
Altimeter – An aneroid barometer calibrated to indicate altitude instead of pressure.
Altitude – A paraglider’s height over sea level; Typically measured in feet, or meters.
Anabatic Flow – Heated air that flows up a slope or mountainside. When at a mountain launch site, these flows may be referred to as “cycles” or “thermals”.
Anemometer – An instrument used to determine wind speed. Commonly known as a wind speed indicator.
Angle of Attack – The angle between the chord line of an airfoil and the vector representing the relative motion between the airfoil and the air.
“A” Risers – The risers on a paraglider that are attached to the “A Lines”, which are attached to the leading edge of the glider. The “A” risers are sometimes used when launching a paraglider, they are activated by the speed system to accelerate the glider, and the outermost “A” line is usually the line used to induce “Big Ears”.
Aspect Ratio – The aspect ratio is equal to the wing span squared, divided by the wing area. Generally speaking, paragliders with low aspect ratios have low performance, and are more stable. Paragliders with a higher aspect ratio are typically higher performing with longer glide ratios, faster, and less stable.
Asymmetric Tip Fold (Asymmetric Collapse) – An event that occurs when one side of a paraglider’s wing loses its loading and is no longer a rigid airfoil. They are a result of turbulence in the air mass a paraglider is flying. the most common occurrence is when a pilot is flying in areas of thermal activity. see Active Piloting.

Base Leg – The crosswind leg of a pilot’s landing approach before the pilot enters the upwind final leg.
Big Ears – A maneuver used by paraglider pilots to increase their rate of descent. The pilot pulls the “Outer A’s”, which lead to the leading edge of the wingtips. Once induced, the wingtips fold down, thereby reducing the area of the wing, and reducing the aerodynamic lift generated by the paraglider. The maneuver is often discouraged by paragliding instructors due to the fact that the pilot no longer feels brake pressure when the Big Ears are in action.
Brake Lines – Lines on a paraglider that are attached to the trailing edge, which changes the airfoil to increase drag. The brake lines are controlled by brake toggles that are kept near the pilot’s hands via pulleys.
Bridle – see “Tow Bridle” or “Y Bridle”
