Note: This calculator uses standard aviation wind triangle formulas. Wind direction is where the wind is coming FROM. WCA with E means turn left, WCA with W means turn right. ETAS (Effective True Air Speed) is shown when WCA exceeds 10° to account for the reduced effective forward speed when crabbing at large angles. All calculations are performed with decimal precision, but displayed values are rounded to the nearest integer for clarity.
