Wind Computer

The Wind Computer encompasses wind-related calculations for in-flight and pre-flight planning uses. It come with with all the wind functions available from an E6B, computing wind components and solving for ground speed, wind correction angle (WCA) and heading for desired a desired course and true airspeed.
 
What the Wind Computer does more than an E6B or a CR-3 is that it computes winds aloft from current airplane speeds, heading and course. By entering assorted combinations of true airspeed, ground speed, heading and course, the Wind Computer solves for the direction and speed of the current winds aloft.
