Takeoff forecasts and a 3D flight viewer for paragliders
2 followers
Free site for free flight pilots in Brazil: 637 takeoffs, a 7-day forecast per takeoff checked against its launch directions, a map of the day's conditions, and a browser viewer for IGC, GPX and KML tracks in 2D and 3D. Android app in closed testing.
Hi, I'm Leandro. I fly paragliders in Brazil and I'm a software developer, so this is the tool I wanted for myself.
Information about our takeoffs is scattered across WhatsApp groups and old pages, and checking if a site will work tomorrow meant opening a few forecast apps and comparing the wind direction with the takeoff's launch directions by hand. Portal do Voo does that comparison for 637 takeoffs, hour by hour, and colors the day by the best window of at least two hours in a row inside the flying hours.
The other half is the flight viewer. Drop an IGC, GPX or KML in the browser and you get the track in 2D and in 3D over the terrain, with replay, altitude and speed. Without an account the file stays in your browser.
It's a Go backend with server-rendered pages, plain JavaScript modules for the viewer and Capacitor for the Android app. Everything is in Portuguese for now and the takeoff catalog covers Brazil only.
The Android app is in closed testing on Google Play, not public yet. Google asks for 12 testers staying 14 days before it can go to production, so if you have an Android phone and want to help, sign up at https://www.portaldovoo.com.br/app with the e-mail of your Google account. The invite isn't instant, I add people to the test list, usually within a day.
Feedback I'd love: does the forecast logic make sense, how the 3D viewer handles your own tracks if you fly, and whether something like this would be useful outside Brazil.
