While not exactly the scenarios discussed above, what concerns me is that 24 is generating routes and waypoints that I did not ask for, even on simple point A to point B with a single fix or VOR in-between. When I define one of these short hops, either in the web based planner or in sim, what gets downloaded to avionics is a bunch of stuff that I did not flight plan for. Then the G1000NXi is full of who know where/what that I have to ignore and just tune the single VOR myself (which is no problem but does not bode well for the kind of longer cross-country examined here).
