VERVIEW
A successful installation should start with careful planning including determination of
mounting location for the GX50/60/65, antenna mounting, cable routing, and other required
modifications. Once the mounting location has been determined, prepare the mounting frame
for installation. It may be easier to complete the wiring harness and attach the connectors to
the mounting frame before installing the mounting frame.

ONSIDERATIONS
The GX50/60/65 is designed to mount in the avionics stack in the aircraft instrument panel
within easy view and reach of the pilot. The standard package includes a mounting frame for
ease of mounting, connections, and service of the unit. Allow an additional one inch clearance
to the rear of the mounting frame for connectors and cables.
For typical installations, the GX50/60/65 does not require external cooling. When mounting the
unit, ensure that a clearance of 1/8 to 1/4 inch exists between avionics units to allow for air
circulation.

NPUT
The GX50/60/65 includes an altitude input, which is used by the GPS RAIM calculations as
well as providing for altitude assist functions such as altitude preset and hold and 3D airspace
alerts. The altitude input is required for installations approved for non-precision approach
operation, optional for other installations.
The GX50/60/65 altitude input can be connected from either an altitude encoder/converter or
an air data converter. The minimum requirements for the altitude input are listed in the
specifications on page 36.
