• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Change Airport Altitude

A quick question that shows how much I know - and don't know - about airport design. I flew out of VHHH/Hong Kong International, and it looked like the runways and taxiways were at sea level, with water in between them. Now, I have been to HK 4 times, and I know it shouldn't look like that. Can one fix that by just raising the elevation of the airport to, say 2 meters, or will that have some unpleasant ramifications?

The airport is an add-on in one file, which is attached.

Thanks in advance -

Jorgen

How do you know that the runways are at sea-level?

In FSX, type <Shift> Z and read the altitude shown at the top of the screen.

That particular file has the airport at the default height of 8.534m (28ft) and displays fine here.

Are you sure you don't have other files for this area?
 
Jorgen, usually water behaves quite persistent (somehow like in real life). You can find some default airports being close to a coastline where parts of the elevated background polys are flooded. I haven't checked your file yet, but it seems to me that your airport is placed in the water and rising the elevation would only rise the water level, too. What you probably want to do is excluding water polygons and coastlines and drawing a new water poly and coastline yourself. As the airport crosses the borders between two QMID rectangles this would mean a a huge amount of work as each coastline needs to be redrawn. As SBuilderX provides some functions making your life more comfortable for such a task, I recommend this tool (for stability reasons you need to save you work often).

Edit before sending:
After loading your airport I cannot see any significant change to the default scenery. Everything looks all right for me, specifically there is no sign of water where it shouln't be. BTW, I'd also been a couple of time in Hong Kong and have an idea how the area should look like. Could you post a screenshot please, so that we can see what worries you. As you only have posted one file, I only can assume that you did not change any ground polygons. Do you have, by chance, any scenery installed that details the old Kai Tak airport and suppresses the new one?

This airport is one of 100's that Ray Smith has designed over the years and uploaded to web sites. If you are having problems with water on runways I would suggest you contact Ray by email which is in his readme.
 
George, you may be onto something here, I do indeed have Kai Tak installed. I can try to move that out of the picture and see what happens. But I seem to remember that I flew out of VHHH before with Kai Tak installed and didn't see water like I did yesterday.

Axel, next time I'll post a screenshot.

Jim, if the other measures fail I will try emailing Ray.

Thanks to you all for your suggestions -

OK, Gentlemen, problem solved. It was another add-on that caused the issue, but not Kai Tak. In addition to that I also had an add-on for Hong Kong city installed. First I took both Kai Tak and the city out, then everything was OK. Put Kai Tak back, still everything OK. Put the city back, problem resurfaced. Since all that the city add-on did that I could see was to render the ferry terminal in Central better, I decided I could live without that. Threw the city out, everything OK again.

Thanks all for your suggestions -

Jorgen - still learning....
