Final Check
Go back to the compass calibration page and check again the corrected data for all 8
directions. The error should now be less than 1
°
– 2
°
(better to have 1
°
). If the errors are
larger then one should search for faults in the installation or in the adjustment procedure.
When the final test is satisfactory your LX9000 is ready to calculate the wind with the
compass method.
The calibration is specific for your combination of aircraft and compass which
means that you cannot transfer the compass to another aircraft whilst using the
same calibration values. It is recommended to repeat the calibration procedure
every year.

Input of Local Magnetic Variation
The correct input of local magnetic variation is essential. Use the QNH and RES menus.
False magnetic variation may degrade the wind calculation significantly. If auto variation is
selected the LX9000 automatically calculates the magnetic variation from a mathematical
model. See Chapter 5.1.1 for more details.

Remote Control
The remote control consists of two parts: a leather coated stick with built-in electronics and
a printed circuit board which connects the wires coming out from the stick to the LX9000
RS485 system bus. The stick is available in three diameters: 18 mm, 20 mm and 24 mm.
