33 GDU 37X CONFIGURATION AND POST INSTALLATION CHECKOUT
The checkout procedures in this section are recommended to be performed after installing the G3X. The
calibration procedures are required to be performed after installing the G3X. It is assumed that the person
performing these checks is familiar with the aircraft, has a working knowledge of typical avionics systems,
and has experience using the test equipment defined in this section.
NOTE
Some procedures in this section require that the GPS receiver is receiving sufficient
satellite signal to compute a present position (
). This requires outdoor line-of-
site to GPS satellite signals or a GPS indoor repeater.
NOTE
As these procedures involve engine run-up and moving the aircraft, it is recommended that
the installer read this entire section before beginning the checkout procedure.
NOTE
Ensure that all GDU 37X displays have been updated to the current software version
before performing any post-installation configuration, checkout, or calibration steps, and
before attempting to troubleshoot any issues. Using up-to-date software ensures that all
previous software improvements are available, and is the most effective first step after
powering on the system. See
for information about updating GDU 37X
software.
NOTE
Unless otherwise noted, all procedures apply to one, two, and three display systems.
CAUTION
Be sure to check all aircraft control movements before flight is attempted to
ensure that the wiring harness does not touch any moving part.
