Can't approach

[Nicola Mastrocola 1361922]

Hello

My problem is that since I've installed ORBX global I can't approach properly anymore. I intercept the localizer, VOR/LOC established, and then no descending path to the runway. The airplane just stucks at the altitude given to the VNAV and says NO AIII. I don't know what to do. Before ORBX everything worked just fine.

Any help would be appreciated.

 

Thank you all.

Hi Nicola,

 

you will need to be a bit more specific:

 

FS-version?

What type of aircraft by what author?

Which airport, which approach procedure exactly?

Prepar3d v3

Any aircraft

Any airport

Just deleted FSUIPC.ini and tried LSZH-LIMC. No way to achieve the landing path.

I forgot. Any procedure.

Ok. You try to fly an ILS at some airport. You are on an intercept-heading for a localizer (LOC), you press APP to arm the approach-mode. Then the plane intercepts the LOC, but when the glideslope (GS) starts moving in, it will not intercept the GS, but rather maintain the last selected altitude? Or is there no GS anymore anywhere?

Yes, it maintains the VNAV altitude and keeps following it. For example, it seems to follow the approach but at a certain time a message says "NO AIII" and maintains planned FL. So I keep flying above the airport but in the right direction for approaching. It's weird because all seems to work fine.

[Andreas Fuchs]

Yes what? It does not intercept an existing glideslope of an ILS or there are no more glideslopes available with the ILS that you are trying to use?

 

And why are you using VNAV when you try to fly and ILS-approach?

I intercept the glideslope normally. I usually click the approach button, don't need to disengage the VNAV, neither the autothrottle. But happens that the autothrottle doesn't disengage and the VNAV remains active.

What plane?

[Nicola Mastrocola 1361922]

What plane?

B737

Okay, so since you aren't answering the questions fully I'm gonna go out on a limb here and make some [Mod - Happy Thoughts]umptions.

 

[Mod - Happy Thoughts]umption 1: It's not really any aircraft, it's just the PMDG B737NGX.

 

[Mod - Happy Thoughts]umption 2: You are using the HGS (HUD) for approach and landing

 

[Mod - Happy Thoughts]umption 3: You have selected "AIII" as your approach mode.

 

Now, I don't have the B737NGX, I just searched "No AIII" and besides the actual real world hits, the only flight sim hits I got were with the B737NGX from PMDG.

 

AIII as I read the articles I found is for use when landing at an airport with a CATIIIB ILS Approach. Maybe the runway you are trying to land on is not CATIII ILS, but only CATII or CATI, thus "NO AIII" and the approach aborts.

 

Try the same approach in a different aircraft, preferably a default one like the default B737 in P3D. See if it works.

 

Try the same approach in the NGX, but don't use "AIII" mode.

 

Try the same approach in the NGX, but don't use the HUD.

 

Try an approach at a smaller airport than LSZH or LIMC to rule out "any airport"

 

Try a different approach at LIMC to rule out "any approach"

Thank you Randy.

Right now I don't have time to test but I think I know what's the problem. AP engages for some obscure reasons CWS, never happened before. So first I have to engage CWS and then AP to enable CMD. Otherwise it will result in CWS mode and failed landings.

Can anyone confirm my opinion?

Thank you

P.S.: I'm not so expert so it's just a hypothesis.

Okay Nicola, let us know.

 

But you still haven't given us much information beyond B737, LIMC, and ORBX. It would really help us if we knew more. Is it the PMDG B737NGX or is it really any aircraft, because most aircraft do not have CWS, usually just payware ones. The specific payware would really, really help us help you.

 

I don't have ORBX, but is the LIMC scenery you are landing at ORBX scenery that you purchased or is it the default with just ORBX Global running in the background? I looked at the default FSX LIMC and there are three ILS approaches available. None of them are CATIII, so AIII on the NGX HUD will not work if I am reading the docomeentation I found correctly. As I said, I don't have the PMDG B737NGX so I cannot test this myself.

 

Also, I know you are using P3D, but I make the [Mod - Happy Thoughts]umption the default LIMC in P3D is the same as the default LIMC in FSX since they are based off the same ESP I believe.

 

I just want to emphasize, the more information you give us the better we can try to help.

Problem solved. The airplane was freeware. I just reinstalled it and it worked.

Thank you guys.
