ILS autotune does not work…

I think ILS autotune does not work, if a secondary flight plan is activated. Here a simple (and academic) scenario to reproduce the problem: Create a primary flight plan, go to secondary flight plan, click “copy active” and then activate the secondary flight plan. The AP perfectly follows the route, but does not autotune ILS. I know that this scenario is in fact useless, but it perfectly nails down the problem. You can try any variation in changing the secondary flight plan before activation, the ILS autotune problem remains. For my installation, the only way around is to reselect (the same) approach / ILS runway. I would be happy if you could try it with your MD-11 – or provide an explanation, what this behaviour is good for. THANKS,Oliver
