ILS 4r

[mortonrb]

When trying to do ILS 4R, I get switched to BCS 222, and I get lined up between the 4's.   I have scanned for duplicates but all I have is AP_KJFK.bgl and appr_kjfk.bgl.

Any help / info would be greatly appreciated.

Works normally here, see the screenshot.

I reinstalled JFK and reran my tests, the results are below.   I am using PMDG 737NGX

I have just completed all tes5/
 
ILS 4L.  No vornav selection.  APP ok
 
ILS 13L all ok
 
ILS 31R. No vorloc selection. APP goes to Bcs 222 landing ok
 
ILS 22R/L. all Ok
 
ILS 31L all Ok
 
ILS 4R. No vornav selection.  APP goes to Bcs 222 IJOC.  Lines up between the 4's
 
Any ideas?

ILS 4L.  No vornav selection.  APP ok

What do you mean with "no vornav selection" ?

ILS 31R. No vorloc selection. APP goes to Bcs 222 landing ok

What do you mean with this ? Please, explain better.

I don't understand exactly what do you mean with "APP goes to Bcs 222 IJOC.", are you referring to a PMDG autopilot function ? If yes, it might not related in any way to the scenery, but to the PMDG internal database.

That's why I tested with the default A321, to eliminate a potential source of confusion.

No VORNAV selection, means that the VORNAV switch will not light uo, ie. be selected.   I have also posted this to the PMDG forum as well.    When I select APP on those ILS which seem to not work properly, it dials in and connects to the Back Course frequency and course.

But does the ILS works normally with a default airplane ?

I removed FSDT JFK and used the stock airport.   Same issue.   109.5 ILS 4R is being recognized as IJOC which is 22R and not IJFK which is 4R.    I have asked this question over at PMDG.   Maybe it is a Navigraph issue.

Umberto:

I found a response in another forum on this exact problem (see below).   I am going to turn off backcourse tonight and give it a try.

Your problem is the way Microsoft setup the default ILS in FS2004 and FSX.
 
Rwy 4R and 22R share a frequency (109.50), Rwy 4L and 22L share a frequency (110.90) and Rwy 13L and 31R share a frequency (111.50) at KJFK. And every one of those ILS is set to enable the backcourse.
 
Which means that if you are not exactly on ILS course, your aircraft will 'capture' the backcourse from the wrong runway. Of course there are not actual transmissions in FS - just a simlation of the effects of radio transmissions.
 
This in not a problem in the real world because none of those ILS transmits a back course, and the ILS for the runways not in use will be turned off to not transmit. But because Microsoft chose to Enable Back Course for every localizer in the entire world - several airports have this issue.
 
There are two options which should relieve your problems, but both require the airport to be edited.

1) Edit the airport to uncheck the default setting of Enable Backcourse on those six ILS at KFJK, or,
 
2) Change the frequencies of one of each pair of shared frequencies.
 
Nr 1 works most of the time for most folks. Nr 2 has the disadvantage of making it harder for you to find the new frequencies if you forget.
 
Something else is that you need to be able to recognize the identifier of the localizer your aircraft 'locks' onto. Some FS aircraft have a HSI gauge which will display that identifier, some will require you to listen to the morse code to recognize the ident.
 
Of course, you have to do your homework and know which is the correct ident, and what are the other idents for the airport should you 'lock' onto a wrong one.

What Airac are you using ? Navagraph have released revision 2 for 1206 navdata, which had faulty sid/stars.

[mortonrb]

I am running rev 2.   Turning back course off has now allowed me to land ILS 4R.
