Optical Surface Recognition (OSR) is a unique technology which can scan surfaces for signs of surface degradation (corrosion). It can also detect corrosion on almost any type of metal, including exposed flat metal, nails, bolts, signs, poles, and grates. PHOTOS Capture photos of corrosion and save to your device's photo roll along with the OSR corrosion score in a custom generated image. VIDEOS Record entire videos with the proprietary OSR corrosion score and save them to your photo roll.

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.
