I just flew KMDW KAMMA KKILR3 KMSP. I had the STAR waypoints in my flight plan up to KKILR, leaving myself about 30nm distance to the airport. When I loaded the flight, I set the altitude restrictions according to the STAR, and flagged KAMMA as the first point of the STAR.

When I reached KAMMA, I got clearance to fly the sierra tango ("stay on this frequency, I'll have traffic), but as soon as I began a scheduled decent, ATC was nagging me about my altitude. I'd thought that once you entered a declared STAR you were left alone until you hit the last waypoint, so I shouldn't have been nagged during the descent. Am I incorrect in this?

(Even if so... why was it asking me to stay at my declared FL, rather than descending to the alt restrictions I set on the flight plan?)

You need to attach your logs in zip form before we can investigate.

Here you go. The instructions in the forum say to email the logs, but you ask for an attachment and that seems to be what folks are doing, hopefully that's correct. :)

I think the instructions have been written before attaching logs here was enabled, and yes, your zip looks fine.

Unrelated to your issue: you may want to upgrade to Little Navmap 1.2.4 :)

From your log:
Code: Select all
Using Adjusted Waypoint Altitudes...
Original Alt (see FPP) for WP 6 changed to: 29000
Original Alt (see FPP) for WP 7 changed to: 24000
Original Alt (see FPP) for WP 8 changed to: 14000
Original Alt (see FPP) for WP 9 changed to: 12000
Start STAR at WP: 1
  End STAR at WP: 9

It seems the altitudes for your STAR waypoints were still at 32000 up to WP5.

This was not "Cleared to final for Sierra Tango approach, runway xx.", but only "continue via", because you had the global STAR option disabled. This is fine if you want vectoring after the last waypoint, but maybe (and I have no idea here) this causes ATC to monitor your altitudes?

Or this could happen because your first waypoint after departure is already the first waypoint of the STAR.

But as written above, I don't know what would be correct here.

Thanks, that's interesting. I'd been under the impression from the forums here that having a STAR set for a particular FP was functionally the same as enabling it globally. Maybe I need to go back and reread about that!
