Total Air Temperature—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.
Heading—required entry for winds aloft calculation.
Use heading from the aircraft’s heading indicator or
directional gyro.
True Airspeed (calculated gure or user entered)—
from entry of calibrated airspeed, baro pressure, and
total air temperature. Also can be entered directly for
winds aloft calculations.
Head Wind (calculated gure)—from entry of
heading and true airspeed.
Wind From (calculated gure)—from entry of
heading and true airspeed.
Wind Speed (calculated gure)—from entry of
heading and true airspeed.
Density Altitude (calculated gure)—from entry
of indicated altitude, baro pressure and total air
temperature.
To calculate true airspeed and density
altitude:
1. From the E6B Page, use the ROCKER to
highlight the Indicated Altitude eld at the top
of the page, and press ENTER.
2. Use the ROCKER to enter the altitude shown
on your altimeter. Press ENTER when nished.
3. Repeat steps 1 and 2 to enter the Calibrated
Airspeed, Baro Pressure, and Total Air
Temperature. (For Calibrated Airspeed,
use the speed shown on your 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.)
4. The calculated gures for True Airspeed and
Density Altitude are shown in the designated
elds.
