The main display panels are
1) A flight computer
2) A list of pilots, showing their wing, a direction arrow towards them, their altitude difference to you and distance away etc.
3) A google map showing; Your position, the pilot markers, thermal hot-spots & controlled airspace nearby, your track history and pilot snail-trails.
Detailed help is provided in the APP itself, with a long-press of the Help "?" button.
Note: Because this is intended as a flying instrument, a 'long-press' is also required on the config and map buttons. This is so they don't accidentally get hit by your harness etc.
