• SC - shows the current SC (Speed Command) value - same as the green arc, as described
in Main page sub-section

Since most of the indicators are self-explanatory, we will cover the ones that are not.
IGC altitude - altitude displayed by the internal IGC pressure sensor, which is not offset by
QNH changes.
Density altitude - the density altitude is the altitude relative to standard atmospheric conditions
at which the air density would be equal to the indicated air density at the place of observation.
Vario AVG - average vario calculated by integration according to given settings (the same
navbox is shown also on Thermal assistant page - AVG).
Vario netto - the actual vertical speed of the surrounding air mass. Is calculated by adding the
current vertical speed indicated by the variometer, and the sink rate of the glider at that speed.
Sink rate of the glider is calculated from the polar.
Vario relative - is Vario netto - 0.7 (sub-tracted for 0.7).
