:wave: Thank you for using the Bug section, using templates provided will greatly help the team reproducing the issue and ease the process of fixing it.

Are you using Developer Mode or made changes in it?

NO

Have you disabled/removed all your mods and addons?

YES

Brief description of the issue:

Since last update: After activating the LOC and when pressing the APPR. button, the plane suddenly seems to no longer follow the direction of the glidescope and begins incoherent turns. This never happened before, and it now happens on several airports even when the ILS frequency is correct :frowning:

Provide Screenshot(s)/video(s) of the issue encountered:

Detailed steps to reproduce the issue encountered:

Simply try an approach phase, and activate the LOC ( FMS should be programmed from the flight planner included in MSFS)

PC specs and/or peripheral set up if relevant:

---- through Game pass cloud gaming and/or XBox with physical game installed

Build Version # when you first started experiencing this issue:

I’m playing through the Game Pass cloud Gaming but i’m usually play it on my Xbox Serie X with the full game installed

Nobody here with the same issue ?

always the same here :frowning: .

During the approach phase on Asobo’s A320 Neo. ILS frequency set correctly and flight plan set up correctly with native Microsoft flight planner.

Everything is OK when activating the LOC and the plane aligns correctly.
But when activating the approach button, the plane loses alignment and begins to turn incoherently.

Very frustrating…and very often the problem no longer occurs on a second approach attempt.

Thank you for your report. The Aircraft Dev Team kindly requests a video to help troubleshoot. Can this be provided?

Here is an example :

Autopilot LOC following gone wrong at 2’58" after LOC activation

(FMC set with native MSFS flight planner)

Approach ILS 01 on EBBR with Star ( TULNI), ILS frequence set on 109.9

( on Cloud gaming with game pass)

I have a lot of the same AP issues on the Airbus! My waypoints sometimes disappear as I get close to my destination. The Airbus cant navigate correctly after last update.

Unfortunately, I have to say that’s true.
Many problems have appeared or even reappeared since the last update (mid februari 2023)

I have noticed many times the waypoint issue you mentionned, disappearing and making the autopilot inconsistent.

I’ve also occasionally noticed the plane starting to loop around a waypoint.

And yesterday, after a one-hour flight on Airbus A320 and on my box series X; black avionics screen, then a few minutes later the game crashed

The game has been pretty stable during my last flight sessions until this problem occured. I was so happy to see it working, and then this happend. As you mentioned - this has been an issue in previous updates, right?

It sometimes makes me question my own skills and wondering what I did wrong in the F-plan / waypoints etc, but obviously the Airbus have had a stroke or something. Takes away the joy with MSFS , especially when Im still trying to learn as a newbie.

I agree with you. It takes a lot of the fun out of it and it’s very frustrating to fly a whole flight over an hour, only to end badly with a bug in the game.
And of course, we often think at first that the problem is our fault.

But after hundreds of hours on the game, I’m starting to know what’s a bug and what’s a mistake on my own.

Too bad too, because I found that in the last few months, the game had become very stable.
(no more crash problem, no more black screen problem, stable AP, etc…)

Hi, for my curiosity I tried a IFR flight ,low alt, from ELLX to EBBR ILS01 :First of all I’ve noticed that in the MDCU , the radnav had the ILS Freq 111.15 preloaded (instead of 109.90) .This was the first signal that something was wrong there. I din’t change it and a flew the route via Tulni.All of the sudden USR waipoints appeared (signal that something was wrong..) Once arrived at the end of the star ,at waypoint CF01 the plane turned left to the final approach.I then pressed LS and LOC…as son as I pressed LOC the plane started turning back-word , deactivating LOC it returned on track. At this point I pressed LOC again with the hope to engage the GS but the plane turned once more and a I let it go.With my surprise the new heading was exactly the opposite of RW01…

I then repeated the flight with approach at RW 19 and noticed that the ILS freq on RADNAV was 111.15 ,correct in this case. So the sim preloaded the same ILS freq for different RWs. I did the flight that ended fine without problems.

Repeated the first flight again for ILS 01 and ,at this time,in the RADNAV I changed the preloaded freq of 111.15 into the correct ones 109.90.
Did the flight and ,again, at the end of the Star ,at WP CF01 I pressed LS and LOC.Right after the plane started to turn again so I immediately un-pressed LOC and the plane returned on final track. Waited for about 10 seconds and pressed LOC again and,at this point, it locked correctly and engaged the GS eventually for a fine landing.

So,something wrong here…

Hello and thank you for your contribution.

As I mentioned, the frequency entered from the built-in flight planner (111.15) for the Runway 01 is not correct.
the correct frequency of ILS 01 is 109.9

It is therefore normal for the LOC frequency 111.15 to be fixed on the opposite axis (ie on runway 19).

But the problem occurs even if I change configure the correct frequency (109.9) in the MCDU for runway 01.

And I must also say that the problem happened on other airports (Lisbon LPPT, Barcelona El prat LEBL)

This is the first time I face this kind of problem. In more than 2 years and more than 100 IFR flights with the Asobo A320 many times I have encountered problems when reaching the Star and missing the Approach because the plane was circling (there is a similar thread with hundreds of posts in this regard) but I never had the ILS freq problem like this. Hope there isn’t a new bug introduced with the latest SU.

I must say actually that I had not yet encountered this LOC issue so far.

On the other hand, I have just experienced the AP which goes crazy and the plane which goes into a spin at the time of the STAR on approach to Brussels EBBR

Do you have the same issue if you follow the OP’s steps to reproduce it?

YES
Provide extra information to complete the original description of the issue:

the aircraft follows its route normally in accordance with the flight plan and randomly begins to turn and no longer follows its heading. He leaves his road for no reason and without any manipulation.
