3.4.2.1.3.6 GNSS Antenna Offset
The GNSS antenna offset is used together with the aircraft length and width to manage taxiway conflicts.
Within the GNSS antenna offset menu, the longitudinal and lateral position offset of the GNSS antenna
can be entered. While mainly important for large aircraft, the values can be entered for small aircraft as
well.
To configure the GNSS antenna offset select “GNSS Ant. Offset” and press the rotary knob. A submenu
“GNSS Ant. Offset” is displayed.
Figure 33: GNSS Antenna Offset Configuration Menu
To configure the longitudinal offset of the GNSS antenna perform the following procedure:
1. Select “Long." and press the rotary knob. The first digit of the offset value turns yellow.
2. Turn the rotary knob to change the value.
3. Press the rotary knob again to save the selected digit. The next digit turns yellow.
4. Turn the rotary knob to change the value.
5. Press the rotary knob again to save the selected digit. The offset value turns green.
Note:
The longitudinal offset has to be entered in meters measured from the nose of the aircraft.
E.g.: If the offset is 3.2 m, the value must be 04.
To configure the lateral offset of the GNSS antenna perform the following procedure:
1. Select “Lat." and press the rotary knob. The “+/-“ sign of the offset value turns yellow.
2. Turn the rotary knob to change the sign.
3. Press the rotary knob again to save sign value. The first digit of the offset value turns yellow.
4. Turn the rotary knob to change the value.
5. Press the rotary knob again to save the selected digit. The next digit turns yellow.
6. Turn the rotary knob to change the value.
7. Press the rotary knob again to save the selected digit. The offset value turns green.
Note:
For most small aircraft a value of “00” is adequate. In case an antenna offset is applicable, the position to
the left side of the aircraft will require a negative sign, to the right a positive sign. The lateral offset has to
be entered in meters measured from longitudinal (Roll) axis of the aircraft.
E.g.: If the offset is 1.3 m to left side, the value must be -02.
