Overview Appendix G E6B Calculator The E6B Calculator calculates Density Altitude, True Airspeed, Tail Wind, Wind From, and Wind Speed, based on information you enter. Accessing the E6B calculator: From the 'Home' Screen, touch Tools > E6B Calc. Barometric Pressure from the Nearest METAR GPS Navigation Additional Features Hazard Avoidance Flight Planning Appendices Calculated Figures E6B Calculator • Indicated 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 automatically 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. 160 Garmin aera 500 Series Pilot's Guide 190-01117-02 Rev. A Index
