Brief description of the issue:

Hi! Posting regarding ILS 31 in Kai tak/VHHX.
Seems to me there’s now a 1 degree offset coded with the station itself in MSFS.
Actual runway magnetic heading is now 317 and FMC database shows inbound course 317 in LNAV (LEGS page).
However the ILS itself is still 316 (Change in magnetic varation not updated?) leading to offset approaches to the right. Is this on Asobo’s side or is this station in Navigraph’s DB update?
Many thanks

I had a reply from a Navigraph Team Member on their forum.
Airport is not updated by Navigraph as it is now fictionnal.
So might be in Asobo’s data. Anyway to have this fixed either by Asobo or by editing files manually in MSFS like in P3D?

Every time landing on MS VHHX the plane is offset on runway ILS 31. Tried with payware VHHX and it still offset exactly on the same spot. I did a video with MS VHHX (Airport Default). Is it a bug?

I appreciate for a help to fix it. Thanks to all.

Just did another video with P3Dv4 to demonstrate the centered landing on VHHX runway ILS 31.

Is it possible to land centered in VHHX runway ILS 31 with MSFS2020 sim?

Workaround could be to try that mod, apparently among others fixes comes one related to the ILS issue: https://flightsim.to/file/4713/hong-kong-kai-tak

code in the ILS for both approaches (13/31) correctly.

You’ll need to uninstall the Asobo bespoke airport to avoid conflict:

Tested that VHHX from that link and it didn’t work. Video here …

Clearly that as longer if the Asobo Studio Microsoft VHHX (Default) keeps the runway ILS 31 Offset it will be a waste to go for a Payware or Freeware regardless of Navigrapgh addon is present or not in the Community folder.

The Navigraph database seems to shift the centre line to the left.

MS only

Navigraph only

But if you follow the line up to the left, to the runway, you can see the dashed line still doesn’t align well with the runway.

What can be changed or editing a specific file as a temporary fix to enjoy VHHX landings in runway ILS 31, it would be nice.

Trisho0 · October 7, 2024, 2:28am

Uninstalling Navigraph the landing is well centered on runway ILS 31. Why Navigraph team is reluctant to correct it the course 316 to change as 317?

Trisho0 · October 8, 2024, 1:32pm

Does anyone know what files need to be edited in order to remove from Navigraph the VHHX airport navdata?

Thibaloo · October 11, 2024, 5:23pm

Trying to figure out this one too… There used to be some very good utility with P3D to do this (SORS AIE) but haven’t found an equivalent software for MSFS so far…

Trisho0 · February 17, 2025, 4:12am

Basically, it has been over than a year now and VHHX still exactly the same results… ILS 31 offset. Wow!

hobanagerik · February 17, 2025, 10:02am

With everything else wrong with what is the current focus of 2024, and its slew of issues, where do you think one mis-aligned ILS sits?

Trisho0 · February 17, 2025, 8:46pm

I can’t answer you because I am not an expert with this. All I can say is, with Navigraph uninstalled my landings with VHHX regardless of if default or payware the touchdown is well centered on runway ILS 31.
But, after Navigraph installed the touchdown is offset. It has been said the Navigraph will correct it but still not fixed.

Trisho0 · February 23, 2025, 10:48pm

I contacted fistful times with Navigraph Support before and after AIRAC 2502 and definitely there is no interest to fix it. So, VHHX doesn’t need Navigraph any longer. Unless someone can help with the procedure to change the heading 316 to 317 in the Navigraph database.
