Operation 

There are no Part 23 aircraft type limitations. All functions of the GMX 200 meet the appropriate design 

assurance qualifications for a secondary system for airplanes in Class I, Class II, Class III, and Class IV in 

accordance with AC 23.1309-1C, Figure 2. The TSO authorizations with the RTCA/DO178B software 

levels by function are listed in Section

Installation 

The conditions and tests required for TSO approval of this article are minimum performance standards. It 

is the responsibility of those installing this article either on or within a specific type or class of aircraft to 

determine that the aircraft installation conditions are within the TSO standards. TSO articles must have 

separate approval for installation in an aircraft. The article may be installed only if performed under 14 

CFR Part 43 or the applicable airworthiness requirements.

If it is necessary to move any required instrumentation in an instrument panel to make room for the GMX 

200, although the physical mounting of the GMX 200 is covered within this installation manual, the 

relocation of these instruments is beyond the scope of the STC. 

For installations where a 6.25” wide radio structure of adequate height is not already approved in the 

aircraft, a separate structural approval is needed for installation of such supporting structure, prior to 

installing the GMX 200.  Such modifications are beyond the scope of this STC.  

In order to provide optimal display view ability (and limit any color shift), the GMX 200 must be 

installed at a height in the panel so that the pilot’s eye will not exceed the 30° downward view to the 

display as illustrated in

For preservation of essential equipment in aircraft with multiple power busses the GMX 200 should be 

powered from the non-essential bus.

Equipment Interfaced to the GMX 200 

GMX 200 interfaces to aircraft systems other than those shown in this installation manual are outside the 

scope of this manual and may require further evaluation and/or certification approval. 

All equipment interfaced to the GMX 200 must be previously or concurrently approved. 

7.2.1.1 

108B

Traffic Sensor 

Only one traffic sensor may be installed. 

7.2.1.2 

109B

FIS Sensor 

FIS data from only one sensor is used by the GMX 200.  When a GDL 69/69A and GDL 90 are installed, 

the GMX 200 will process the FIS data from the GDL 69/69A and traffic data from the GDL 90, ignoring 

the FIS data from the GDL 90. 

7.2.1.3 

110B

Terrain Sensor 

Only one TAWS sensor may be installed.  Configuration of TAWS sensor and internal terrain function 

are mutually exclusive. 

7.2.1.4 

111B

Radar Sensor 

Only one radar sensor may be installed. 

7.2.2

Preservation of Previous Systems 

It is the installer’s responsibility to preserve the essential characteristic of the aircraft being modified by 

this manual to be in accordance with the aircraft manufacturer’s original design. This includes the 

preservation of multiple power buses, which reduce the probability of interrupting power to essential 

instruments and avionics.
