Plan and analyse
ParaFlightBook includes several XC/FAI planning tools (like Tom Payne’s XC-Planner in 2 versions, one of them capable of delivering not only the waypoints but also the sectors as pseudo airspaces for older instruments). There is also an offline XC/FAI planner.
The flight analysis is capable of looking for thermals in tracks and to track them back to the point where they were “born”. These thermal spots can be used as waypoints and printed as thermal maps.
