GWX 68 Installation Manual
Preliminary Revision 1
190-00286-01
3.4 Unit
Installation
The GWX 68 is designed to be rigidly mounted in the nose section of the aircraft. If the nose section is
not accessible, pod mounting is possible. The bulk head or antenna mounting plate must be very close to
perpendicular to the aircraft center line. The selected location must have adequate clearance for the full
antenna sweep and tilt range. See Appendix A for outline and installation drawings. The nose section
does not need to be pressurized.
It is crucial to the performance of the GWX 68 weather radar system that care be taken in
alignment of the GWX 68 unit with respect to the aircraft.
1.
Refer to Figure A-1 mount the GWX 68 using the hardware provided.
2.
Assemble the GWX 68 connector kit, see Section 3.3.
3.
Check unit for clearance in all extreme positions.
4.
Ensure wiring harness is routed in such a way that it can not be struck by or interfere with the unit
movement through the full sweep and tilt range.

Post Installation Configuration & Checkout
The GWX 68 does not provide valid outputs until the aircraft post installation
configuration procedures are completed.
When installed as part of the G1000 integrated cockpit system, the GWX 68 must have FAA approved
configuration data. Configuration data is loaded to the GWX 68 from an aircraft-specific G1000
Software Loader Card. Settings are predetermined for a specific aircraft and are typically contained
within the file named ‘TBD’.
The GDU 1040 PFD serves as the graphics user interface to the installer configuring the system. For
basic configuration information, refer to the G1000 Line Maintenance and Configuration Manual, Garmin
part number 190-00303-04. For actual aircraft installation/checkout, use only aircraft manufacturer
approved checkout procedures.
For GWX 68 installations operating with a Garmin MX20, refer to MX20 Installation Manual,
560-1025-09.
3.6 Continued
Airworthiness
For sample Instructions for Continued Airworthiness (ICA) for the GWX 68 installed as part of the
G1000 integrated cockpit system, see the G1000 ICA Sample, Garmin part number 190-00303-07.
Other than for regulatory periodic functional checks, maintenance on the GWX 68 is “on condition” only.
Refer to the G1000 Line Maintenance and Configuration Manual, Garmin part number 190-00303-04.
