    662. Task distance is the shortest way to fly the task from TP1 and touching the cylinder edge on tp2 where it is the shortest route from tp1 to tp3 via the edge of tp2.

    1616Tp3 (on top) is with 3km radius.
    17 The task distance in !CompeGPS as in the official results is: 60.7km.
     17The task distance in CompeGPS as in the official results is: 60.7km.
    1818The task distance in [WikiStart FS] is 52.5km.
    19 The difference is because of !CompeGPS calculates total distance as the distance into the center of each turnpoint not taking the cylinders into account.

    2020The blue line is the long version with total distance as the excact TP to TP distance.
    2121The red line is the shortest distance possible for pilot to fly the task, as done by [WikiStart FS].

     23We can look at the flights of 3 pilots.

     26First two did not make the TP3 (pilot1 red, pilot2 black):

     43According to the distance calculations in CompeGPS (and in the official results) the pilot3 did get 6km longer distance than the other two pilots by just entering into the 3km radius cylinder.

     46Official results:[[BR]]
     47Pilot3 : 16,9 km[[BR]]
     48Pilot2: 11,3km[[BR]]
     49Pilot1: 10,9 km

     52[WikiStart FS] calculates the [TaskDistance task distance] as the shortest distance for pilot to fly the task.
     53
     54
     55The distance a pilots has flown is then the [TaskDistance task distance] minus the shortest distance the pilot must fly to finish the task.
