MENU
The ‘E6B’ file tab provides the following settings:
• INDICATED ALTITUDE—required entry for density altitude/true airspeed calculation. Use
altitude displayed on your altimeter.
• CALIBRATED AIRSPEED—required entry for density altitude/true airspeed calculation. Use
speed displayed on your airspeed indicator.
• BARO PRESSURE— required entry for density altitude/true airspeed calculation. Use current
altimeter setting (barometric pressure).
• TOTAL AIR TEMPERATURE—required entry for density altitude/true airspeed calculation. 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.
• DENSITY ALTITUDE (calculated figure)—determined from entry of indicated altitude, baro
pressure and total air temperature.
• TRUE AIRSPEED (calculated figure or user entered)—determined from entry of calibrated
airspeed, baro pressure and total air temperature. Also can be entered directly for winds aloft
calculations.
• HEADING—required entry for winds aloft calculation. Use heading from directional gyro or
compass.
• HEAD/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 airspeed.
If a True North reference is currently selected on your GPSMAP 295 (see page 77), you
must enter HEADING using a True North reference to accurately determine winds.

Winds aloft calculations will provide a head/tail wind
component, wind direction and wind speed.
True Airspeed is calculated by entering the required figures
and may then be used for determining winds aloft. Or, you
may enter the True Airspeed from an alternate source.
