QuickWindChk vs RunwayWX

QuickWindChk puts the wind picture you need before a flight decision into one clear, focused view. Enter the runway heading, wind direction, and wind speed to understand the wind at a glance. Wind Envelope — Check your wind margin quickly and clearly. Set crosswind and tailwind limits, then see the remaining margin clearly. Pattern HDG — See the traffic-pattern direction that fits your runway, along with wind-corrected headings for each leg. Choose left- or right-hand traffic, set TAS, and switch the pattern presentation UP or DOWN for the view that is easiest to read. You can also: - See headwind, tailwind, and left or right crosswind components instantly. - Use a clean runway-and-wind diagram to understand the result visually. - Enter data quickly with the purpose-built keypad. - Lock runway or wind-direction values for repeated checks. - Use light or dark appearance on both iPhone and iPad. Important! QuickWindChk is a fast reference tool. Always use current official weather information, aircraft limitations, airport procedures, and approved flight-planning resources when making operational decisions.
