2.2 Variometer
The variometer calculates climb or descent rate by measuring air
pressure differences.
This value is almost instantaneously indicated on the Analog-
Vario-Display, while the averaged rate of climb or descent (within
a selected timespan) is shown in the Digital-Vario-Display.
2.2.1 Analog Variometer (direct vario)
Currently the analog variometer is limited to a range
of
+

10 m/sec.

800 ft/min
climb
150 ft/min
descent
averaged climb rate of
120 ft/min
2.2.2 Digital Variometer (averaged variometer)
The period of time for the average climb/descend rate calculation
can be selected from 1 to 32 seconds.
Example: To determine the average climb/descent rate within a
complete 360° turn, you choose a value of approx. 10 to 15 sec..
This feature is very useful if you find yourself circling alternately
in ascending and descending air.
