  • Page 22: Mounting Considerations

    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.

  • Page 23: Air Circulation And Cooling

    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).
