Würde ich gut finden. Zumindest eine Linie die mir, wenn ich die Route verlasse , immer die Richtung zum Ziel zeigt.  For me  this sounds like a good idea.  I like to have a line that always show me the direction to my Target Arrival Airport If i Away Form my plant Route.

This info is already available in the route log and would possibly clutter the screen.  Especially on short legs between reporting points inside a CTR this does not help.

sounds like a good idea ? to me however I do understand that issues coming with it. for myself I have solved the issue by placing an infield with the true bearing to the active waypoint.
