5.4.1 GEA 110 Removal
To remove the GEA 110, perform the following procedure:
1. Remove power from the GEA 110.
2. Disconnect the two electrical connectors.
3. If the unit is mounted on a tray, as shown in Figure 5-7, pull out on the mounting knob and turn
counterclockwise to loosen it enough to rotate the arm down and away from the unit.
4. If the unit is mounted to the airframe using screws, as shown in Figure 5-6, loosen the four screws
securing the unit to the airframe.
5.4.2 GEA 110 Re-installation
To re-install the GEA 110, perform the removal procedures in reverse. If the unit is mounted to the
airframe, torque the screws to the specification in Figure 5-6. For units that are mounted in a mounting
tray, tighten the mounting screw by hand until the unit is secure.
If the GEA 110 was replaced, the sensor configurations must be loaded to the new unit using the following
procedure:
1. Power on the GI 275 that is directly interfaced to the GEA 110 into Configuration mode.
2. Insert the USB drive containing the saved configuration into the USB dongle or GSB 15. A USB
icon should appear in the bottom-left of the display once the GI 275 has recognized the device. If
the icon doesn’t appear after 1 minute, remove the drive and re-insert it.
3. Touch the
SW/Config
button, then the
Config Options
button.
4. Touch the
Import Configuration
button.
5. Touch the
Select Files
button and select the appropriate aircraft configuration file.
6. Touch the
Select Configuration
button.
7. Touch the
EIS Sensor Config
button to select it. Touch the
Back
button.
8. Touch the
Import Config
button and then the
Start
button.
9. A restart is required to complete import. Touch the
Restart Now
button.
5.4.3 GEA 110 Checkout
Perform the Configuration Mode Ground Checks described in Section 5.14.1. If the GEA 110 does not
pass the checks in this step, reload the sensor configurations using the procedure in Section 5.4.2 and
perform the checkout procedure again.
If the GEA 110 was replaced or did not initially pass the checkout procedure, perform the EIS Ground
Checks described in Section 6 of
GI 275 Part 23 AML STC Installation Manual
(P/N 190-02246-10).
