QuickWindChk vs Crosswind Check

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.

Know what the wind is doing across the runway. Crosswind Check gives pilots a clear, visual way to calculate crosswind, headwind and tailwind components and a practical way to get better at estimating them without a calculator. Enter the runway and wind, or use the latest available METAR for an airport. Crosswind Check shows the resulting components and visualizes where the wind is coming from relative to the runway. CHECK WIND COMPONENTS Enter a runway, wind direction and wind speed to instantly see: • Crosswind component and direction • Headwind or tailwind component • Sustained and gust components • Wind component percentages • Wind angle relative to the runway Switch between North Up and Runway Up to view the same conditions from two useful perspectives. USE LIVE METAR WIND Enter an airport ICAO code to retrieve its latest available METAR. Crosswind Check shows the reported wind and, where supported, converts true wind direction to magnetic for use with runway headings. Save frequently used airports as Favorites for quick access. Selecting a Favorite makes a fresh METAR request rather than reusing a stored weather result. TRAIN YOUR CROSSWIND ESTIMATE Knowing the exact answer is useful. Being able to estimate it is even better. Train mode gives you runway and wind scenarios to work through mentally. Estimate the crosswind range, determine whether you have a headwind or tailwind, and choose the appropriate control input. Reveal the answer to compare your reasoning with the calculated result and see a simple rule-of-thumb explanation. BUILT FOR PILOTS Crosswind Check is deliberately focused. No account. No setup. No advertising. Just a clear tool for understanding wind relative to a runway. Designed for iPhone and iPad. IMPORTANT Crosswind Check is a supplementary calculation and training aid. It does not determine whether a flight is safe or whether conditions are within an aircraft's operating limitations. Always verify weather information, runway data and applicable aircraft limitations using appropriate authoritative sources before flight.
