Note: This calculator uses standard aviation wind triangle formulas. Wind direction is where the wind is coming FROM. Positive WCA means turn right, negative means turn left. ETAS (Effective True Air Speed) is shown when WCA exceeds 10° to account for the reduced effective forward speed when crabbing at large angles. For complete flight planning with fuel, time estimates, and waypoints, use the Leg Planner.
