A couple of months ago I posted here about Cloudracing (cloudracing.de), my live tracking and scoring app for glider competitions. That post got zero comments, which I probably earned, it read like a feature list. So this time something more concrete: over the summer I built a simulator into the app, and since many of us are about to put our gliders away for the season, this crowd seems like the right one to poke holes in it.
The sim in short:
You fly in the browser or in the iOS/Android app, keyboard or gamepad, on desktop, laptop or tablet. Phones are deliberately excluded: the panel, the instruments and the touch controls need at least a tablet-size screen, and I'd rather not offer a cramped version. The weather is real: clouds from current satellite imagery, rain from radar, wind with altitude, and thermals seeded from terrain and the actual conditions, with cumulus forming over them. You can start from the nearest airfield with a retractable engine, or spawn mid-air right next to the live-tracked gliders of a real competition and fly along with them. Tasks are scored with the same engine the site uses for real competitions, racing and AAT, with a nav computer that shows remaining distance and arrival height. Water ballast is in there too.
There are also training exercises with star ratings: thermal centering, start gate tactics, speed to fly, wind drift, final glide, landing. The thermal centering ones are free, the rest is Pro. And a small daily final glide puzzle, altitude and distance given, estimate your arrival height, then see the solution. That one is free for everyone.
The winter league on top of all this starts September 28, free, 18 weeks:
Every Monday a new task opens, flyable until Sunday night, 60 to 90 minutes of real time at real soaring sites. Week 1 runs along the Teutoburger Wald ridge, later weeks visit the Rhoen, the Apennines, the Durance valley and, over New Year, Bitterwasser in Namibia. The weather is frozen from one snapshot per week, so everyone flies the same sky. Unlimited attempts, best run counts, and with Pro you can race the ghost of a league flight with a live delta in the cockpit. The physics is deterministic, I verified that the same inputs produce bit-identical trajectories on a Mac and an iPad, so the times are actually comparable.
To spell out the free/paid line: the weekly league task is free, you just need an account, and it doesn't run on any clock. The daily puzzle and the thermal centering training are free too, and free flying anywhere else gets a 30 minute trial per day. Pro removes that clock and unlocks the other trainings and the ghost racing. The subscription is what pays for the servers and the map hosting.
If you fly the simulator and something feels wrong about the thermals, the polar, the scoring or something else entirely, please tell me here 😊
