About

WCA Toolbox

Features
Read full description

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. Features • Wind correction angle, heading, groundspeed, and wind components • Magnetic inbound track entry for holding patterns • High-precision holding prediction with complete-pattern wind modelling • Right- and left-hand holding patterns • 1:00 and 1:30 inbound-time presets • Clear pilot-facing inbound and outbound heading guidance • Saved calculations stored locally on your device • Fully offline operation • Portrait-only, full-screen interface for a focused workflow Important notice WCA Toolbox is intended for flight-planning assistance only. It does not replace published procedures, ATC instructions, aircraft documentation, operational judgement, or instructor guidance. Always use current, authoritative aviation information.
