• I ndicated Altitude—required entry for density altitude/true airspeed calculation.
Enter the aircraft’s altimeter reading.
• Baro Pressure—when the unit is receiving XM weather information, the field auto-
matically updates to the barometric pressure of the nearest METAR. If XM weather
information is not available you need to enter the current barometric pressure.
• Calibrated Airspeed— required entry for density altitude/true airspeed calculation.
Enter the aircraft’s airspeed indicator value.
Total Air Temp • — required entry for density altitude/true airspeed calculation. Total
Air Temperature (TAT) is the temperature of the air including the heating effect caused
by speed. The temperature reading on a standard outside air temperature gauge found
on most piston aircraft is TAT.
Heading • — required entry for winds aloft calculation. Use heading from the aircraft’s
heading indicator or directional gyro.
