2.2 Variometer
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
recognize when he is sinking too rapidly in descending
air and should leave them at best speed.
The scale of the analogue display is 0,1 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 time constant of Analogue-Vario is factory set
to 1,2 s. In the Set-Mode (Vario-Speed-Average)
this value may be adjusted between 0,6 … 3 s.
In case of short time constant the Vario is very bumpy,
with a long time constant it will be somewhat sluggish.
2.2.2 Digital Vario - average value or Netto Vario
The Digital Vario has a scale of 10 cm/s and a vast 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 may be useful to observe the
average climb inside a rough thermal.
The Digital Vario may also be operated as Netto Vario which displays the condition of
ambient air. Please also read 9.2 Vario for this topic.
In addition it is possible to set the Digital Vario in such a way that it operates during the climb
as integrating Vario, and during sink as Netto Vario. (Set-Mode / Basic Settings/ Variomode )
2.2.3 Acoustics and Volume Level
Brief pressing of the key ; /Goto will increase volume level each time by 25%. The adjustable
sound levels are: 0 - 25% - 50% - 75% - 100% - 0. The selected value is displayed on
the info line.
Automatic volume control:
with the basic setting levels 25 50 u. 75 % volume level will be
slowly increased automatically, once the airspeed exceeds 40 km/h. However, it is impossible
for the volume level to exceed 100%.
The following settings are possible to be entered in the Set-Menu under " Basic Settings /
Vario tone
".
Ascent Freq.:
the ascent acoustics start at a climb rate of 0,1 m/s. This is a frequency
modulated interval tone whereby the pitch and frequency increase rhythmically at increasing
climb rate. The pulse/pause ratio is 1:1.
