2.5.2 Setting Options – Step by Step
2.5.2.1 Activate the Automatic QNH Setting Once each Time when
being Turned On
This option allows to define whether the device
initiates one automatic QNH determination each
time after being turned on, or not.
In both cases the device starts with using the
standard QNH 1013 hPa / 29,92 inHG.
The automatic setting of the QNH requires GPS availability, because the
GPS altitude is used as a reference for determining the QNH. If no GPS
position could be determined within a fixed time interval, the standard
QNH is continued to be used, see p. 15.
2.5.2.2 Automatic Flight Time Display after each Landing
It is possible to select having the flight time
displayed only after being selected manually
(“man”) or additionally automatically after each
landing (“land”).
2.5.2.3 QNH – Unit
The QNH can be given in Hektopascal (hPa) or
inch of mercury column (inHG).
The selection of the settings is done with the
keys
.
2.5.2.4 Altitude – Unit
The altitude can be provided in feet (ft) or in
meter (m). An additional cue for the values
given in feet (ft) are the downsized last two
digits.
2.5.2.5 Rate of Climb – Unit
The rate of climb is provided either in meter per
second (mps) or in feet per minute (fpm). The
