2.3.2.1 Battery Indication
The battery symbol reflects the charge state of the battery. In case the
battery is not charging and the charge state is low, the battery symbol
will be depicted in white instead of grey. If the charge state becomes
critical, the symbol will additionally be inverted:
An arrow
in front of the battery symbol indicates an active charging
process, a check mark the completed charging.
At temperatures significant below the freezing point (below −5°C/+23°F)
the charging functionality is reduced, and the battery state cannot be
determined correctly during charging. In this case the battery symbol
changes to the display
, until the temperature rises again. Even in
this case, however, the discharging use (use of the device without having
aircraft power supply) is still possible.
At extreme temperatures (below −15°C/+5°F and above
+45°C/+113°F) the battery cannot be charged, as otherwise
it would be damaged permanently.
The discharging use however (use of the device without
having aircraft power supply) is still possible.
2.3.2.2 QNH Indication
The QNH indication gives the pressure setting, which is used fort he
determination of the baro-altitude. The unit of the QNH is configurable
(see 2.5.2.2). Additionally it is indicated whether the QNH was set
manually (M). or determined automatically (A).
The automatic QNH-dertermination is started by a
long press of
gestartet; see (ch. 2.4)
for
QNH management.
While the automatic QNH-determination is in
progress (this requires a valid GPS position), the numerical value fort he
QNH is substituted by „----“. During this indication the last QNH value is
