In the example shown, the indicated altitude is 5000 feet, barometric
pressure is 30.02”, outside air temperature is 59° Fahrenheit, and the
calibrated airspeed is 129 knots. This gives us a pressure altitude of
4908 feet, a density altitude of 5740 feet, and a true airspeed of 140.4
knots. Obviously, you don’t need airspeed to calculate density altitude,
this was done for illustration purposes.

E6B Wind Speed/Direction Calculator
To determine the wind speed and direction, first find true airspeed us-
ing the Altitude/Airspeed Calculator. Once you have that, open the
Wind Speed/Direction Calculator.
A screen similar to the one in the following image appears. The current
true airspeed is automatically used, and you only need to enter your
heading. Use the arrow keys to change the heading in the box at the top
of the screen.
In the example shown, the heading is 39° magnetic. This gives us a
wind speed of 11.4 knots on a bearing of 42° magnetic, for an 11.4 knot
headwind.
