Much more than in other types of aviation, glider pilots depend on the variometer, which is a very sensitive vertical speed indicator, to measure the climb or sink rate of the plane.
42.
In addition to TE compensation, the Netto variometer adjusts for the intrinsic sink rate of the glider at a given speed ( the polar curve ) adjusted for the wing loading due to water ballast.
43.
When the variometer is showing a climb, the tone is often chopped and the rate of chopping may be increased as the climb rate increases, while during a descent the tone is not chopped.

The Professor's hexagonal, ply covered, deep flat sided fuselage tapered strongly aft . The pilot sat in an open, unscreened cockpit immediately ahead of the pedestal and equipped with the variometer.
45.
Certain camera angles, including the Three-Way View and 3-D Cockpit view, provide the player with simulated flight instruments such as an altimeter, airspeed indicator, accelerometer, variometer and tachometer.
46.
An uncompensated variometer will simply indicate vertical speed of the glider, giving rise to the possibility of a " stick thermal, " i . e ., a change in altitude caused by stick input only.
47.
Variometers also became important in foot-launch hang gliding, where the open-to-air pilot hears the wind but needs the variometer to help him or her to detect regions of rising or sinking air.

49.
When thermalling, the sensor will detect acceleration ( gravity plus centrifugal ) above 1 g and tell the relative netto variometer to stop subtracting the sailplane's wing load-adjusted polar sink rate for the duration.
50.
Conversely, descending air is announced with a lowering tone, which advises the pilot to escape the sink area as soon as possible . ( Refer to the " variometer " article for more information ).
