2.6 Mounting Considerations The GTR 200 is designed to mount in the avionics stack in the aircraft instrument panel within view and reach of the pilot. The primary unit location should minimize pilot head movement when transitioning between looking outside of the cockpit and viewing/operating the GTR 200. The location should be such that the GTR 200 unit is not blocked by the glare shield on top, or by the throttles, control yoke, etc. on the bottom. If aircraft has a throw-over yoke, be sure the yoke does not interfere with the GTR 200. 2.7 Cabling and Wiring Refer to the interconnect examples in Appendix D for wire gauge guidance. Use wire and cable meeting the applicable aviation regulation. When routing wire and cable, observe the following precautions: • Keep as short and as direct as possible • Avoid sharp bends • Avoid routing near power sources (e.g. 400 Hz generators, trim motors, etc.) or near power for fluorescent lighting • Do not route cable near high voltage sources CAUTION To avoid damage to the GTR 200, take precautions to prevent Electro-Static Discharge (ESD) when handling the GTR 200, connectors, and associated wiring. ESD damage can be prevented by touching an object that is of the same electrical potential as the GTR 200 before handling the GTR 200 itself. 2.8 Air Circulation and Cooling The GTR 200 unit meets all requirements without external cooling. However, as with all electronic equipment, lower operating temperatures extends equipment life. Reducing the operating temperature by 15° to 20°C (27° to 36°F) reduces the mean time between failures (MTBF). Units tightly packed in the avionics stack heat each other through radiation, convection, and sometimes by direct conduction. Even a single unit operates at a much higher temperature in still air than in moving air. Fans or some other means of moving the air around electronic equipment are usually a worthwhile investment. 2.9 Compass Safe Distance After reconfiguring the avionics in the cockpit panel, if the unit is mounted less than 12 inches from the compass, recalibrate the compass and make the necessary changes for noting correction data.

2.6
Mounting Considerations
The GTR 200 is designed to mount in the avionics stack in the aircraft instrument panel within view and
reach of the pilot.
The primary unit location should minimize pilot head movement when transitioning
between looking outside of the cockpit and viewing/operating the GTR 200.
The location should be such
that the GTR 200 unit is not blocked by the glare shield on top, or by the throttles, control yoke, etc. on the
bottom.
If aircraft has a throw-over yoke, be sure the yoke does not interfere with the GTR 200.
2.7
Cabling and Wiring
Refer to the interconnect examples in
Appendix D
for wire gauge guidance.
Use wire and cable meeting the applicable aviation regulation. When routing wire and cable, observe the
following precautions:
•
Keep as short and as direct as possible
•
Avoid sharp bends
•
Avoid routing near power sources (e.g. 400 Hz generators, trim motors, etc.) or near power for
fluorescent lighting
•
Do not route cable near high voltage sources
CAUTION
To avoid damage to the GTR 200, take precautions to prevent Electro-Static Discharge
(ESD) when handling the GTR 200, connectors, and associated wiring.
ESD damage can
be prevented by touching an object that is of the same electrical potential as the GTR 200
before handling the GTR 200 itself.
2.8
Air Circulation and Cooling
The GTR 200 unit meets all requirements without external cooling.
However, as with all electronic
equipment, lower operating temperatures extends equipment life.
Reducing the operating temperature by
15° to 20°C (27° to 36°F) reduces the mean time between failures (MTBF).
Units tightly packed in the avionics stack heat each other through radiation, convection, and sometimes by
direct conduction.
Even a single unit operates at a much higher temperature in still air than in moving air.
Fans or some other means of moving the air around electronic equipment are usually a worthwhile
investment.
2.9
Compass Safe Distance
After reconfiguring the avionics in the cockpit panel, if the unit is mounted less than 12 inches from the
compass, recalibrate the compass and make the necessary changes for noting correction data.
