As this is not a one-off, I'd really like to find out what the problem is and how to solve it.
ATC seems to be working quite happily and starts to bring me down towards the destination. But at 50nm from the airport I am still at FL270: ATC seems to have forgotten me. I thought that PF3 wasn't finding the correct frequency - but If I press '0' to check in, ATC acknowledges me, but doesn't request I descend further and I end up either just doing my own thing in order to land or I just continue - flying over the airport at FL270 (or whatever) to see what happens. Well, nothing.
Any ideas? The flight plan itself is just fine and in any case, this problem isn't restricted to any particular plan.
Thank you.
