ATC Aircraft do not pushback

Version: 1.1.7.0

Frequency: Consistently

Severity: Blocker

Marketplace package name: /

Context:
Injected AI airplanes do not depart.

Similar MSFS 2020 issue: No, there it works fine

Bug description:
Injecting an airplane via SimConnect with AICreateEnrouteATCAircraft and waypoint 0.0 spawns the aircraft as expected at the gate and it changes directly into "STATE_PUSH_BACK_BEGIN. But it never starts the pushback, using DevMode “Debug AI Path” is is visible that the path to the taxiway is set correct. Same issue when injecting as AICreateParkedATCAircraft and setting the PLN later.
Tested at default LPPR, with and without Ground Vehicles enabled in the Settings. Pushback Truck never connects.

Repro steps:
Inject any airplane via AICreateEnrouteATCAircraft with waypoint 0.0 value.

Are ATC aircraft receiving a pushback at all? I have seen them doing all kinds of weird things, among it that they don’t receive a pushback, which of course ends up in making weird turns with wings into terminals when departing. Happens both at default and addon airports.

I have not checked default live AI yet

Most pushbacks I’ve seen so far do work, similar to 2020. Some get stuck after making the “spin-around” after pushback though.
In terms of pushback with AICreateEnrouteATCAircraft or AICreateParkedATCAircraft injected aircraft, I’ve seen them pushback if they stick around long enough with the parking issue, but I don’t know that we inject with the waypoint 0.0 value or not. I’ll see if I can find out.

AIG injects with both: Parked and Enroute - same issue for both…


not sure what changed, but they pushedback just fine, but seems blocked shortly after. Will investigate further and report back.

and update:

seems to have “unblocked” itself in a second where no airplane was “stacking” on the parking spot…

From some additional testing, it appears the AI aircraft get stuck in STATE_PRE_TAXI_FOR_TAKEOFF, and never switch over to STATE_TAXI_FOR_TAKEOFF.
From the scenery I’ve tested with, this happens more if the parking taxi path is short. If I extend the parking taxipath, allowing the aircraft to pushback farther from the parking spot, it seems pushback is more likely to be successful.
Not sure why that is…

Same thing at LFPG with default live AI and default Scenery. Either they do not push and disappear or pop-up on taxiway to taxi or sometimes swivel from gate and taxi without pushing back. I don’t know whether it’s related but when AIs come to a rest at a gate, jetways start to move toward the aircraft and immediately retract.

This is still an issue in sim v1.2.7.0. See attached images. The parking on the left has a short parking taxipath while the parking taxipath on the right is longer. Aircraft parked on the right will pushback and transition to STATE_TAXI_FOR_TAKEOFF as expected.
But aircraft that park on the left, will pushback, turn around and remain in STATE_PRE_TAXI_FOR_TAKEOFF.


can confirm the isue is still there in Patch#3

@FlyingRaccoon additional info:

seems that the pushback trucks are not used for AI Traffic pushback - this was working in FS2020 without issues.
