difference between known reference magnetic headings and by the headings shown on the window. This
error is more or less constant regardless to the direction. Write down this difference for a few different
directions and calculate the average. Enter this final correction using the
Compass Offset
option. When the
compass readings were too large, enter negative value and vice versa.

6.9.5 Firmware Update
This command updates the software of devices present on the CAN bus: AD-AHRS module (Airu), EMS
module (Daqu), compass module (Magu), etc.
Do not use this function unless we advise you to do so.
6.9.6 RamBoot Update
This command updates the startup software, which takes care for the instrument start.
Do not use this function unless we advise you to do so.
6.9.7 Logger Settings
Here we can tune some logger specific parameters. These parameters are used to identify conditions for
the take-off, landing and engine start/stop.
•
Take-off threshold specifies IAS, which must be exceeded for a few seconds for a logger to detect
and record a take-off event.
•
Landing threshold specifies IAS, which must be kept below for a few seconds in order to detect
the landing event. This also works in conjunction with Rotor RPM.
•
Rotor RPM threshold shall be defined for helicopters and gyroplanes only. In order to detect the
landing situation, we logger monitors two things: IAS and rotor RPMs. They both must be below
the specified thresholds in order to detect the landing. This prevents false landing detections,
which happen if Rotor RPM threshold is not used.
•
Engine RPM threshold is used to detect the engine start or stop event.
