[SU11 Beta] - Variance in handling AI injected plans vs SU10

I have a simple example piece of code injecting 3 plan files via AICreateEnrouteATCAircraft using pure C++ simmconnect. The plans place aircraft at 3 points on an approach route to KLAX and are identical except for the starting point being slightly further out for each. In SU10 all 3 planes will land. On SU11 the first one will land, the 2nd one will eventually overfly the airport while still climbing past 10,000ft, the 3rd one turns and heads in the opposite direction from the airport never to return.

I'm looking for confirmation of changes that would have impacted this behaviour and indication if it will be looked as a bug.

I do note that the altitude in SU10 is inserted incorrectly but in SU11 it is more accurate (related to live traffic altitude changes perhaps). Maybe this then leads to the odd behaviour in SU11 approach. But ultimately SU11 leads to lots of aircraft overlyflying airports and circling before landing and some planes never trying to land at all - different from SU10.

This link is a video of the aircraft moition in little nav map in SU10 - exact same code and plans.

Update:

After leaving the SU11 test running for an extended time - Plane 3 finally landed after about an hour and lots of ciruits above the airport. After an hour Plane 2 is still doing circuits above the airport at 6000ft.

Hello @whakamolenz

We suspect those aircraft are waiting for crowded runways to be available.
There has been some changes with traffic density and behavior with SU11 and we are aware of some issues with AIs not using all available runways and causing some traffic jam.
Can you check if this is the case here? (by disabling base traffic)

Regards,
Sylvain

Appreciate the response but when this test is running no other ai is enabled. These are the only 3 aircraft in the sim over and above the user aircraft.

Ok, thank you for the feedback. We are investigating this.

Hey,

I will run some Stress-Test on the AI System next weekend and provide you with detailed Feedback.

@FlyingRaccoon - is there a liklihood of improvements to this issue in the final release build of SU11. Currently this is going to cause significant issues for us if released in the current state, with no obvious workarounds.

Hello @whakamolenz @Kaiii3

No, we haven't addressed those issues in SU11.
We are still in the process of reproducing and identifying the problem.
Regards,
Sylvain

Hey Sylvain, thanks for the feedbacl. Do you need anything from us to help reproducing the issue?

Not sure if this is related, but we did a small test with the NavData BGL (CYYZ) and some legs do not have any altitude values assigned, could this be an issue? Btw: Running the same ApproachLegs via the FacilityData Request, we always got Altitude1 and 2 set to "0" even if there are a few Legs in the BGL that have a value for Altitude1 assigned.
