9.3 UTC time and date
If the device has a valid GPS source, the current UTC time (above) and date (below) will be
displayed in the right section below the “GPS status”.
9.4 OAT
Current outside air temperature will be displayed as ”OAT” value. If the value seams wrong,
please check if the OAT sensor is connected according to the installation manual.
OAT line is not displayed if OAT sensor is not connected or does not work properly.
9.5 Density altitude
Density altitude is pressure altitude corrected for nonstandard temperature. As temperature
and altitude increase, air density decreases. In a sense, it’s the altitude at which the airplane
”feels” its flying.
9.6 Current power supply voltage
Current voltage will be displayed. The unit is Volt (V).
Pilot must be careful if the voltage drops below 9V or is higher than 32V.
9.7 Battery
Actual backup battery voltage is displayed as “Battery”.
Pilot must be careful if the voltage drops below 3V or is higher than 5V.
Backup battery is automatically charged all the time it is powered on and will automatically
switch to the power source in case of electrical failure.
NOTE
The use of the internal backup battery will be activated automatically only when in
flight mode. Flight mode starts when the device detects flight conditions through
its sensors. Approximately 5 minutes after losing its GPS signal, the device will
conclude the flight and shutdown.
When the device is not in the flight mode, the device will turn off upon loosing
main external power supply, without using its internal backup battery.
