Lachez
Read full descriptionHide full description
Lachez shows where every balloon at the event is right now – and shows the pilot what lies ahead. A balloon goes where the wind takes it. With Lachez, you'll see where. FOR PILOTS Airspaces and power lines directly on the map, a side view of the route ahead of the basket, and wind by altitude. Open the AIP of the country straight from the airspace card; for Czech airspaces the VFR Manual, today's AUP and NOTAMs, and for TSA/TRA today's activation from the AUP. Airfields with runways and frequencies one tap away. Projected flight direction 5–40 minutes ahead, based on the balloon's movement so far. Location sharing keeps running with the phone in your pocket and the screen off – you switch it on and off yourself. The app detects take-off and landing; every flight is kept in your history with a profile, track and GPX. FOR GROUND CREW Open the event map and see every balloon in the air at once. Pick yours and start navigation to it with one tap. No more guessing from the side of the road. FOR PASSENGERS, FAMILY AND SPECTATORS Follow the flight on a live map – in the app, or via a link from the pilot in any browser, no installation needed. After landing you get a flight card with route, altitude and a photo to share. FOR ORGANIZERS Every balloon on one map, events secured by a pilot code, with a briefing for pilots and crew (also offline). Scoring for fly-in and longest distance (Gordon Bennett), support for fox hunt. HOW IT WORKS No accounts, no registration – choose your role, pick an event or set up your own private space and invite your crew with a code. Lachez is free. Lachez speaks 9 languages: Czech, English, German, Slovak, Polish, French, Italian, Spanish and Turkish. Made for pilots, crews, balloon meets, fiestas and competitions. By balloonists.
