[SU12B] AI Changes - Arrival Traffic [Improvement confirmed]

Hey Sylvain @FlyingRaccoon to take SU12B to
the limtis we have disabled all our workarounds in AIGTC Traffic Controller.
Regarding the arrvial AI traffic issue we have reported in SU11B I can report
that we are now back to pre SU11 AI state based on our initial tests. AI is
arriving but seems to not follow STAR aproaches setup in the airport - we will
do more tests on this over the next days. (I have not seen this fix in the
ChangeLog, only a fix for departing live AI traffic) Can you tell us what you
guys have changed and what AI should do/what we should expect to happen? This
would make testing a bit more easier and we can report with more details.

Hello @Kaiii3 The AI selecting the appropriate STAR
is part of the “Fixed SimConnect injected traffic planes not following the
assigned flight plan” line. I’m not sure what I’m supposed to conclude from
your picture… What STAR have you assigned to your AIs? Can you provide us
with those specific flight plans and dFlightPlanPosition passed to your
SimConnect_AICreateEnrouteATCAircraft call? Regards, Sylvain

We have not assinged any STAR or Runway to the flightplan, the last waypoint
in the PLN is about 80-100nm away from the airport, because based on our
understand internal ATC would take care of assigning SID/STAR. It is a bit
hard for us in SimConnect to asigned SID/STAR or Runways since we do not know
the ATC assinged runway when creating the PLN on runtime or the METAR to
calculate what runway should be used. We have tested in SU11 to add SID/STAR
and AI was ignoring them, so if this is now possible I have to rewrite some
parts or write a “Test-App” and report back. If SID/STAR for ATC controlled AI
need now to be added to the PLN to be effective we need more access via
SimConnect to get needed information - will get back to you on that later.

In addition: Internal ATC STAR assingment worked in SU11 a bit (it always
assinged the first STAR in the airport list), so my hope was that the (“always
only one STAR”-Bug would be fixed and the internal ATC now takes all STAR and
the AI airplanes position into consideration when assigning the STAR.

Ah ok I understand your point. Well, no, if you don’t provide a SID/STAR in
your flight plan, ATC will not assign any.

ok, so we are back to the “old” way ATC works and the partial added STAR
assignment from the last update (that was bugged) has been removed completly?

Yes, ATC forcing the first STAR of the list regardless of what you asked for
will no longer happen. I get your point that ATC should assign a coherent STAR
if you don’t provide one. This will be discussed.

Personally FSLTL likes the way its working now - as we can assign STARs using
our own logic rather than the sim ignoring what is in the plan. So we wouldn’t
want to have the sim forcing a STAR of its own choosing if one is provided in
the plan.

I would suggest having a flag inside the PLN informing the Sim if SID/STAR and
Runway from the PLN should be used or if the Sim needs to assign those. At the
moment there is no way to make sure runway, SID and STAR assignment 100%
corrent with just the Data provided via SimConnect…

Yep would agree that would be a good solution. We are using alternative
functions outside simconnect to get METAR data from the sim.
