mechanical variometer
Device that indicates the glider’s vertical rate of climb or descent by mechanical means.
electric variometer
Device that indicates the glider’s vertical rate of climb or descent by means of an electric sensor; it is more accurate than a mechanical variometer.
airspeed indicator
Device indicating the speed of the glider with respect to the air through which it is moving.
cockpit ventilation
Device that controls the opening and closing of air vents to provide air circulation within the cockpit.
seat

canopy release knob
Lever that detaches the cockpit canopy from the fuselage so the pilot can eject in case of emergency.
microphone
Device that converts electric pulses into broadcast or recorded sounds.
oxygen feeding knob
Device used to activate the system that provides the pilot with oxygen when the glider climbs to high altitudes.
oxygen feeding control
Device used to regulate the pilot’s oxygen flow.
turn and slip indicator
Instrument with a gyroscope connected to a pointer that indicates the rate and direction of turning; it also has a ball that shows if the glider is rolling sideways.
compass
