• 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
Enter the aircraft's airspeed indicator value.
• Total Air Temp
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.
• Tail Wind
— (calculated figure) determined from entry of heading and true airspeed.
• Wind From
—(calculated figure) determined from entry of heading and true airspeed.
• Wind Speed
—(calculated figure) determined from entry of heading and true air-
speed.
• Density Altitude
barometric pressure and total air temperature.
• True Airspeed
— (calculated or user-entered figure) determined from entry of
calibrated airspeed, barometric pressure, and total air temperature. This can also be
entered directly for winds aloft calculations.
Calculating true airspeed and density altitude:
1) From the E6B Calculator Page, enter the altitude shown on the altimeter
into the 'Indicated Altitude' field, and press the ENT Key.
