Virtual PAPI vs VocalFit Pro

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.
