- Worth noticing
- The page separates deployment into exit, line stretch, inflation, and 1:1 glide, with stage and cumulative measurements.
Field notes
The described workflow starts with an imported FlySight track or a bundled recording, which can be trimmed to the section a jumper wants to study. The page says a device library carries recordings, selections, and preferences across tools. It also distinguishes estimated exit times from confirmed jump times and warns that gridded historical weather may not match conditions at a cliff or along a flight.
