2.8 Air Circulation and CoolingThe GTR 200 unit meets all requirements without external cooling. However, as with all electronicequipment, lower operating temperatures extends equipment life. Reducing the operating temperature by15° 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 bydirect 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 worthwhileinvestment.2.9 Compass Safe DistanceAfter reconfiguring the avionics in the cockpit panel, if the unit is mounted less than 12 inches from thecompass, recalibrate the compass and make the necessary changes for noting correction data.
