WCA Toolbox is a focused aviation calculator for wind correction angle (WCA) planning and holding-pattern wind prediction. Enter a course, wind direction, wind speed, and true airspeed to receive clear, pilot-facing guidance for wind correction angle, heading, groundspeed, headwind or tailwind, and crosswind. Results are presented in a clean format designed for quick flight-planning use. For holding patterns, WCA Toolbox calculates inbound and outbound guidance from your magnetic inbound track and true wind data. The high-precision method models the complete racetrack, including both turns and straight legs, using a standard turn rate of 3° per second. It then determines an outbound heading and timing that aim to achieve your selected inbound time. A conventional 3× WCA approximation is also included as a familiar reference.
