2.2 Variometer functions
2.2.1 Analogue 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 consistently 0,2 m/s
over both scale ranges ! The range of the first scale extends
from 0 up to +/- 4 m/s. (fig. 1) There after the scale display
switches automatically to the second scale range which
extends from 4… 8 m/s. The second scale is afterwards
displayed with a white bar on black base. (fig. 2)
The response characteristics of the analogue Vario and of
climb- or sink acoustics can be adapted within a wide range
in accordance to pilot’s needs or the weather
conditions. In order to simplify the settings, Flytec has
defined 5 basic- resp. turbulence filters.
Tip: By use of the PC Flychart Software Extras ->
Flightinstrument Options
, all Vario characteristics can be set
easily and comfortably. With the tone simulation the
adjusted values can easily be checked simultaneously !

2.2.2 Digital-Vario (Average 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 and record even measuring flights up to the free fall.
2.2.3 Variometer Acoustics and Volume level (Sound)
In order to enable the pilot to follow the current sink rate without looking on the instrument, the Vario-
Acoustics generate a tone sequence dependent on the value data. The Vario-Acoustic corresponds
always to the value of Analogue-Vario.
The sink acoustic of the variometer can be adjusted in the FLYTEC 6040 instrument to the
personal needs of the pilot.
