## What is QuickWindChk?

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.
