Wind Correction Angle
True course + TAS + wind → wind correction angle, true heading, and groundspeed. The wind-side of the E6B, fast enough to redo at the runup pad.
Inputs
Desired track over the ground, 0-360.
From the POH / planned cruise TAS.
Direction wind is blowing FROM (METAR / winds aloft).
Verdict
—
Enter true course, TAS, wind direction and wind speed
What you point the nose at — course + WCA.

About this calculator
Classic E6B wind-side math. Crosswind = wind × sin(angle off course). WCA = asin(crosswind / TAS). True heading = course + WCA, normalized to 0-360°. Groundspeed uses the exact form GS = TAS × cos(WCA) − headwind rather than the small-angle approximation, so it matches an E6B at all wind angles.
If the perpendicular wind component exceeds your TAS, no amount of crab will hold the desired course — the tool flags “cannot maintain course.”
