After update ILS still broken

[FlyingsCool5650]

Is that an addon airport?

Hello I hope you are well. This problem exists since previous updates, to be precise since v1.8.3.0 the landing assistant stopped working correctly, then in the following updates the ILS data of many airports failed, it has been reported many times to the support team and In each new update it worsens, they have not been able to fix it, the problem is in many airports, not all, but I would dare to say that in 85% of airports this problem is found, in the previous update the data was more correct, but in this new update the error is present more and more. Cheers

So we can say that ILS is NOT broken, especially not in general, but the AP’s APP-Hold doesn’t work as it should in some locations.

Correct, nor in the TBM.

Can someone post an airport where this happens so I can test it. I haven’t had any issues.

[Paladin569]

are you sure that the airport does not have an ILS offset? My hoime airport ILS is offset 2 degrees

[Crunchmeister71]

I had 2 failures to capture the localizer and glide slope at 2 different runways - 1 at CYYZ and one at CYGK. And I mean completely missed. These are ILS approaches I use all the time and never had an issue with. Then a third attempt at CYGK seemed to work just normally like it always did. I didn’t do anything different than normal or of the attempt right before.

This is weird. I’m going to have to experiment with this some more when I get home from work. This isn’t right.

One thing that appears to have changed in this patch is the rate of turn when under autopilot control. Previously, when (for example) making a 90 degree turn using heading select, the aircraft would roll into the turn almost instantly - likewise for rolling out when the selected heading was reached. Now, it appears the turn initialization is much more “gentle” for lack of a better word. In the Cessna, the aircraft starts in a 5 degree bank, which gradually increases to about 20 degrees midway through the turn, then very slowly rolls out when approaching the heading.

This slower turn rate also appears to exist when capturing an ILS localizer. Though the “smoother” turn entry and exit is probably great for “passenger comfort”, perhaps they have gone too far in damping down the rate of turn.

Possibly, (especially with a crosswind), the aircraft is now turning too slowly to capture a localizer “with authority”, which could also lead to problems correcting drift away from the centerline. when a strong crosswind exists.

I have done 3 ILS approaches so far. One in the TBM and two in the 172. All tracked well eventually, but it did seem that the aircraft was taking quite a long time to get established due to the shallower and slower turn entries and exits.

MUHA departure airport, MUVR destination airport, flight path VR500 AGDEM VILBA, flight level 5,000 feet, landing ILS to runway 06, frequency 111.30 MHz. Regards

That’s funny, I was landing at EGLL 09 R (Edit: Not 9R, I was landing on 27R - the opposite of yours) last night and my ILS tracked to the left of the runway by about 100 metres (on the grass verge). I had to abort the AP and land manually.
I was flying the Grand Caravan. Never had a problem there before the update.
I must try it again to check things.

Edit: Tried again today (25/11/2020) and I had no problem. It tracked to centre line. I also noticed what HalberQuacky posted with the “slow” turn in capturing the approach and the oscillation.

[Jamilzeira82]

yes it is broken, every day I do my morning flight from SBGR to SBCT with TBM 930 and mod A320 neo round trip. But today after update 1.11.6.0. The ILS of any runway that landed are not aligning centrally with the runway, it this shifting 05 degrees to the right or left depends on the arrival procedure. Making the plane land on the grass or aprrons. Much lack of what to do in ASOBO instead of fixing it just bugging the SIM more>

I’m flying your test airport now

@FlyinMousaka746

ILS tracked to the left of the runway by about 100 metres (on the grass verge).

That’s what happened to me at ILS 5 at CYYZ. Only I was tracking about 500m to the left.

[TheAviator1653]

OK thanks. The error is so rare that sometimes it can align you but the altitude is very high, and other times the altitude and alignment is totally wrong. Now I’ll be recording a video at another airport, then I’ll leave it here. Regards

[Detail50]

Pretty much center cut, it might have been a tad to the right, but I didn’t see a big error

[Detail50]

Sled, I’ll try yours a little later on. EGLL ILS 09L.

The other case I just ran worked perfectly, turned onto final picked up LOC and then keyed APR, flew the GS right down to runway

[Crunchmeister71]

As it should be.

I don’t know what caused the issues I had. I’ve been doing ILS landings for months now without any issue, especially at the 2 airports. I don’t even need to look up ILS plates at this point. I know the frequencies and altitudes, restrictions, and missed approach instructions off the top of my head. I did go and double check the plates when I saw it wasn’t working, and everything was as it should be.

And why I couldn’t capture the ILS in one flight, but it worked perfectly at the same airport and same runway on a subsequent flight is beyond me.

When I get home from work I’ll do some more testing and see if I can get to the bottom of this.

[FlyinMousaka746]

I edited my previous post above. No problem today.

[TheAviator1653]

Hi. I leave the video where the problem with the ILS is clearly seen in this case at the SLVR airport, I leave all the necessary data to test this flight in the description of the video. Regards.

Whelp… I had zero issues and it flew it perfectly. I didn’t touch or correct autopilot once and disengaged over the threshold and it put me right where it should. Slight cross wind. No mods installed, live weather.
