Calibration
1)
Physically point the aircraft precisely to one of the cardinal headings.
2)
The compass pointer on the PC will now show the MT102 readings
with the
coarse calibration applied
. This is reference information only – it still shows
magnetic error left after the coarse calibration.
Note:
The fine calibration at the cardinal headings can be done in any
order.
3)
Use the compass rose or sight compass to align the aircraft.
4)
Wait until the Rate Meter indicator is in the green and click the appropriate
“Calibrate” button.
5)
The button will turn green and ‘OK’ appears in the text box.
Note:
The compass pointer will not change position.
