Final Check; Input Of Local Magnetic Variation; Remote Control - LXNAV LX8000 User Manual

LX8000 (LX8080) Version 2.6
At the end press the OK button to save the calibration data or press CANCEL to cancel the
changes in which case the previous settings will remain.
Switch the unit OFF by using the OFF button to store the calibration data properly.
The calibration data will remain until next calibration procedure.

10.5.4 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 than one should search for faults in the installation or in the adjustment procedure.
When the final test is satisfactory your LX8000 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.

10.5.5 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 LX8000 automatically calculates the magnetic variation from a mathematical
model. See Chapter 5.1.1 for more details.

10.6 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 LX8000
RS485 system bus. The stick is available in three diameters: 18 mm, 20 mm and 24 mm.
All necessary electronics is built into the top of the stick and only the wires from the control
tube to the interface unit need to be used. This solution makes the installation very easy.
Additionally two shielded cables are used for speed command key and PTT.
Do not forget to set the speed command input setting to TASTER (see Chapter
5.1.12.1).
The original stick grip should be removed and replaced with the new one. On the top of the
new grip there are 9 push buttons. An additional button positioned on the front side is for
