Virtual PAPI vs BlockTimePro

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.

BlockTimePro is a pilot-focused companion app designed to make filling out your aircraft’s official logbook easier, faster, and mistake-free. Instead of calculating flight and block times, day/night minutes, or fuel usage in your head, BlockTimePro generates it all automatically. You simply copy the results into your paper or electronic logbook with confidence. From flight planning to post-flight recording, the app keeps everything organized locally—so you can focus on flying while BlockTime handles the math. • Accurate Calculations for Logbooks: Enter show, takeoff, landing, and engine-off times in UTC; BlockTime auto-calculates flight and block times ready to copy. • Day/Night Breakdown: Automatically splits minutes between day and night. • Smart Time Suggestions: Sequential hints reduce typing errors. • Fuel Calculator & Costs: Track start, remaining, consumed fuel and compute uplift cost instantly (kg, lb, L, gal; USD/EUR/BRL). • Flight Planning: Distance, track, TAS, winds, groundspeed, ETE, dual ETA (UTC & Local) with date rollover. • Airport Database (Offline): Import global ICAO dataset for quick lookup (OurAirports). • Offline-First: Flight and plan data stored on-device; fast and private. • Free Trial then simple monthly subscription. Built for pilots who still write in the logbook—BlockTime does the math so you don’t make mistakes.
