Garmin GPSMAP 296 Manual De Usuario

The E6B tab in the Main Menu calculates Density Altitude, True 

Airspeed, and Winds Aloft (Head Wind, Tail Wind, Wind From, and 

Wind Speed), based on information you enter. 

1.  Press 

MENU twice to open the Main Menu. 

2.  Highlight 

E6B from the vertical list of tabs.

Indicated Altitude—required entry for density altitude/true airspeed 

calculation. Enter the aircraft’s altimeter reading. 
Calibrated Airspeed—required entry for density altitude/true 

airspeed calculation. Enter the aircraft’s airspeed indicator. 
Heading—required entry for winds aloft calculation. Use heading 

from the aircraft’s heading indicator or directional gyro. 

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. 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.
Head 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.
True Airspeed—(calculated or user-entered figure) determined from 

entry of calibrated airspeed, baro pressure, and total air temperature. 

Also can be entered directly for winds aloft calculations.
Density Altitude—(calculated figure) determined from entry of 

indicated altitude, barometric pressure and total air temperature.
