the tubes that form a triangle around the pilot and that's used for controlling the hang glider

the speed that an aircraft passing through the air

A steep turn in a hang glider or paraglider

the horizontal tube that the pilot uses to control the glider during prone flight. Same as a "Control Bar^?"

"Boundary Layer" is used in free-flight as the lower portion of the atmosphere which is affected by the earth's heating. This is typically the lowest 2-3kms of the atmosphere, extending from cumolous clouds (if any) to ground level.

the horizontal tube that the pilot uses to control the glider during prone flight. Same as a "Base Bar^?"

The centre of a thermal (not visible) where the lift is the strongest

the two vertical tubes that the pilot holds on to during take off and landing. Same as "uprights^?" used in Australia

the whirling winds of dust seen in dry areas, that happens to be the bottom of a thermal, and is caused by the Earth's rotation

a speed bar^? built by Moyes that is built with aluminium that has been shaped (extruded) to be aerodynamic

a group of hang gliders and/or paragliders all circling up in the same thermal updraft

Injected nylon, which is popular for performance frames of sunglasses, such as those designed for active sports, because it is very strong and durable, as well as being light and flexible.

Catching a thermal in your hang glider or paraglider from only a few hundred feet above the ground, and taking it back UP!

Flying low in lift patchy lift, trying hard to stay/get back up in a hang glider or paraglider

a glider that is so high it's barely visible from the ground

a curved control bar^? (or base bar^?) that is shaped forward to allow a pilot to pull in more during flight, creating more airspeed^?

A hang glider without the top rigging (kingpost and luff lines)

the two vertical tubes that the pilot holds on to during take off and landing. Same as "downtubes^?" used in the USA

-or called a "variometer^?", it's an instrument that displays the rate of climb or decent in a glider, and is also the term used for a flight instrument in general (displaying altitude, airspeed^?, GPS position, and etc...).

-or called a "vario^?", it's an instrument that displays the rate of climb or decent in a glider, and is also the term used for a flight instrument in general (displaying altitude, airspeed^?, GPS position, and etc...).

A hang gliding landing where the pilot doesn't get the flare timing right and drops the nose on the ground.

Inside a cloud, with no sense of direction (up, down, sideways) which is also called vertigo

Two or more people assisting a hang glider pilot on launch in high winds, by holding onto the side/nose wires of the glider.
