Go/No-Go · Glider
Know the soaring day before you tow
Pick a launch site and up to three operating areas. The briefing tells you when lift starts, how high it goes, and where you can land if it quits.
What the briefing covers
Soaring window and thermal tops
When usable lift starts and ends, how high thermals reach and how strong the climbs are.
Cumulus or blue day
Whether you will have cloud markers, plus overdevelopment risk later in the day.
Landouts within glide
Airports within a safe glide of each area. Areas with no landout are called out plainly.
Landing area odds
Pick a desired landing area and see the odds of reaching it, with airports along the course.
