Density Altitude
: To figure the Density Altitude, type in the Outside Air Temperature
in Celsius (OAT). Use the slide bar underneath the text box to get close and then fine-
tune it with the arrows on either side of the text box. When a temperature is entered, the
deviation from ISA is computed and saved. If you re-enter this screen later in the flight,
the temperature value will be remembered and filled in for you. Tap the Density ALT
button, and it will be displayed in the gray box above the button.
True Airspeed
: Enter the Indicated Air Speed (IAS) in the text box in knots. Use the
slide bar underneath the text box for a general number, and fine-tune it with the arrows
on either side of the text box Tap the TAS button, and it will be displayed in the gray
box above the button.
Winds Aloft
: Enter the Magnetic heading of the aircraft in the box shown. The GPS
reported ground track is shown in the Track box. Tapping WINDS will cause the actual
winds aloft to be calculated and displayed. This step assumes that the altitude,
temperature, and airspeed have already been computed. To have a visual reminder of
the wind data just entered, tap Show Vector. To hide the wind vector, go to the Flight
Plan screen and tap WINDS > HIDE VECTOR.
