Simple Xwind vs Virtual PAPI

You're on short final when the tower provides updated winds. The conditions have changed more than expected, and there’s no time for mental math to determine if you're within crosswind and tailwind limits. Xwind gives you quick and precise calculations when you need them most. No clutter, no unnecessary graphics—just a fast, reliable crosswind calculator built for ease of use. Unlike other bulky apps, Xwind is designed for speed and simplicity, so you can get the data you need instantly. No extra clicks, no distractions—just numbers.

Pilots love runways with visual descent guidance, such as PAPI or VASI, but unfortunately they don't exist everywhere. This app provides an adjustable visual descent guidance for every runway on the planet. The pilot can select an airport, a runway, adjust the desired descent angle and the aiming point, then Virtual PAPI will create a glide slope indicator style. The glide slope will provide accurate vertical guidance to the aiming point from any direction, 360 degrees, providing a valuable guidance for any type of approach, like base entries, short approaches, straight-ins, etc. The app comes with over 30 thousand runways in its offline database, and more will be added as they are discovered. The app works completely offline and never tries to use the internet. All it needs is access to your location. Virtual PAPI is and free and open source, with all the code available on GitHub.
