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— (calculated figure) determined from entry of indicated 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.

1)   From the E6B Calculator Page, enter the altitude shown on the altimeter 

into the ‘Indicated Altitude’ field, and press the ENT Key.

2)  Repeat for ‘Calibrated Airspeed’, ‘Baro Pressure’, and ‘Total Air 

Temperature’ fields.  (For Calibrated Airspeed, use the speed shown on 
the airspeed indicator.  Use the current altimeter setting for Baro Pressure.  
Total Air Temperature is the temperature of the outside air including the 
heating effect caused by speed.  For most aircraft, this is the temperature 
reading on a standard outside air temperature gauge.) The calculated 
figures for True Airspeed and Density Altitude are shown in the designated 
fields.

1)   Calculate or enter the true airspeed into the ‘True Airspeed’ field, and press 

the ENT Key.

2)  Enter the aircraft heading shown on the directional gyro or compass into 

the ‘Heading’ field, and press the ENT Key.  Head/Tail Wind, Wind From, 
and Wind Speed are calculated.
