What's wrong in this picture?

This is Naples international airport or Capodichino landing on ILS runway 6. I turned on the visual navigation aid that says I’m right on the correct path but look at the gauge which has it way off to the left. Is this a bug or is their a certain way you need to fly this approach?

Saw this last week as I flew this approach. Trustet the ILS (no visual navigation), but it guided me to the gras on the left. So I did a go around and did a visual landing at night.
I assume its a bug or an offset between scenery and the code behind the glidepath. I don’t know how these two interact or if every ILS is coded separately, since the visual aid looks alright.

Yes, you can’t land it with the AP following the glideslope. I know sometimes ILS are offset due to adjacent runway but there is no adjacent runway here. I think it’s a bug.

LIRN ILS 06 is an offset approach, check the remark on the chart top left. Strictly following the glidepath you will end up slightly left of the runway threshold.

Littlenavmap is showing the offset too.

But that doesn’t explain the magenta needles and the angle of approach. I don’t fly the Airbus but these magenta needles might show your NAV/GPS flightplan. Shouldn’t these needles be green for the ILS LOC approach?

Yes I’m above the glideslope here as I did a go around and was concentrating on finding out what was wrong with the approach and was flying manually, so I turned on the visual aid to see how it corresponded. I figured it was something like this. So how does one actually fly an offset approach like this? I’m guessing you have to do it manually by the instruments.

Seems a visual approach defeats the purpose of an ILS.

As it says in the chart - Final Approach Course intercepts Center Line Extension 0.75 NM before THR - my best guess is at 1 NM before THR you kill the AP and bring down the bird manually. But I’ll ask a RL pilot.

Interesting. Learn something new everyday.

Same for me :+1: thx @OliveGerste65

I remember the first time I stumbled across an offset ILS. It was Boston, with IMC down to 300’ . I broke out of the clouds to realize the runway was over to my right…I managed to land it, but it wasn’t pretty. (I was in either the CJ4 or the Longitude) I then proceeded to learn that offset ILS is a thing… I never would’ve guessed

Delete please

It is actually quite common IRL to fly the ILS approach manually, this is much more fun for the pilots and of course it has the positive effect of keeping in practice.

In case of emergency you have to be able to do it anyway, what good is it if you have let the autopilot do it all your life.

If you listen to Live ATC more often (tower frequencies), you are sometimes lucky to hear the typical sound when the PIC turns off the AP while the other pilot is talking to the controller.

With CATI, II or III conditions this is a completely different story of course.

Thats a point I say very often IRL with autopilots on cars. When I drive, I want to drive myself.
With the airliners I mostly handfly the SID/ STAR just for fun (I don’t know how its done IRL) and with GA/ VFR <20nm before the destination.
I don’t like to be downgraded to a passenger XD

I must say the view on this approach is awesome. I’ve been to Napoli a number of times and that’s exactly how it looks.

SID/STAR - typically with AP support for some obvious reasons - these are the most vulnerable sections of a flight.

SID: you’re busy with a lot of tasks like ‘after takeoff checklist’, gear up, flaps up, checking your engine parameters to maintain positive climb rate, looking out for other traffic, talking to the departure controller, awareness for disruptions like system failures, bird strikes. Then it’s convenient if the AP follows the assigned SID and manages your climb rate, the trimming as well as the speed.

More or less the same is valid for the STAR: while you’re descending you have to focus on your papers/charts, the mandatory checklists, and then again looking out for other traffic, talking to the arrival controller, awareness for disruptions like system failures, bird strikes. Then it’s convenient if the AP follows the assigned STAR and manages your descend rate, the trimming as well as the speed.

Of course values for heading, descend or climb rate will be adjusted manually when the ATC controller gives such instructions.

At some point, when you are convenient with the overall situation on the flightdeck, you might decide to switch off the AP for training purposes.

Hi guys, here is a little gift for you to practise the offset ILS. It’s not a perfect mod, I’ve cleaned up and added something here and there. Modified the approach lights and PAPI4 according to RL charts and added apron lights for night immersion, though no changes were made to the ILS of course!
