What are all the bits called?

Rudder: Will not turn the glider on its own, but only assists in lining up the fuselage with the airflow. Used together with the ailerons in flight. Provides a yawing force.

Elevator: Provides pitch control to lower or raise the nose and thus control the speed.

Tailplane: Provides horizontal stability.

Fin: Provides Longitudinal stability.

Aileron: Used to bank the glider - work differentially so that when the right aileron goes up, the left goes down and vice versa. Used with the rudder to turn the glider

Airbrake: Used to control the rate of sink of the glider for landings

Canopy: Made from perspex, usually incorporates a small opening window (called a direct-vision, or DV, panel)

All gliders will have three basic instruments - The air speed indicator (or 'ASI'), the altimeter, and a variometer. All others seen here would be optional. This would be the panel of a typical cross-country single-seater. There is a GPS (Global positioning satellite receiver) used for navigation, this would probably be linked to a logging device so that the flight could be replayed through a PC on landing, showing the exact height and location at any time during the glider's flight. The artificial horizon would be used for flying inside clouds where applicable and the radio for communicating with other aircraft as well as ground stations. Two variometers are shown here, these are devices to measure the rising (or sinking) air the glider is flying through. One of these would be a purely mechanical device, while the other would be a fast-acting electronic unit that would be more sensitive. It would also be coupled to an audio unit which would emit a series of increasing 'beeps' in rising air.
