2.2 Variometer functions
2.2.1 Analog Vario
The most important indication for a non-motor driven
aircraft is without any doubt the Variometer.
It displays the vertical speed in meter/second and informs
the pilot about the actual climb or sink rate.

It is only possible for the pilot by using the Vario (and its
accompanying acoustics) to determine the most efficient
thermal climb, and in the opposite situation, to recognise
when he is sinking too rapidly in downwind and should
leave them at best speed.
The scale of the analogue display is 0,2 m/s. The range of
the first scale extends from 0 up to +/- 4 m/s, thereafter the
scale display switches automatically and the range of the
second scale extends from 4… 8 m/s.
.
The response characteristics of the analogue Vario and of climb
acoustics can be set within a wide range. In order to simplify
the settings, Flytec has determined 5 basic filters which can be
set by the Flychart program to particular requirements when
using a special command.

2.2.2 Digital-Vario Average- or Netto-Vario
The Digital Vario has a scale of 10 cm/s and an extensive measuring range of
up to +/- 100 m/s. It is therefore also appropriate to display the vertical speed for parachutists
during the jump.
It may be provided with a time constant from 1 … 30 s in the Set-Mode under "Variomode"
as average value-Vario (also called integrating Vario). This feature is useful to provide a
more settled Vario display inside a rough thermal. Integration time should be selected more
longer in accordance to the thermal’s roughness.
