• 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.

Removing default runways

I have made quite good progress learning SBX and FSX_Planner but there is one thing that is eluding me so far that hopefully someone can help.

The default runway of the airport I am designing is set at an altitude which is 300ft higher than it should be. I have managed to remove everything of the default airport except the runway and the FSX entry.

My addon scenery is at the correct priority level and indeed everything else I have done works. I just cannot get the sim to start at my new airport, it always starts in mid air.

Is there something really basic I have overlooked?

Any help would be gratefully received.

Hi Colin.

You need to make a "stub" for the airport. The airport takes it's elevation from the first instance of elevation in the sim's datastream. So if your airport gets a tiny stub that is placed before the default location in the Scenery Library, that stub will control all future elevations.

This has been true since fs9.

Here's an example of a stub:

Code: 
<?xml version="1.0"?>
<FSData version="9.0"
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xsi:noNamespaceSchemaLocation="bglcomp.xsd">

<Airport ident="C59"
  region=""
  country="United States"
  state="Wisconsin"
  city="Delavan"
  name="Lake Lawn"
  lat="N42 38.04750"
  lon="W088 36.06700"
  alt="200.00M"
</Airport>

</FSData>


Save this as 'C59_stub.xml' and compile the xml file with BGLComp. This will set C59 to 200 meters.

The resulting 'C59.bgl' should be placed previous to your new airport's BGL in the Scenery Library. I make a folder named 'Stubs' in the FSX main Scenery Folder, and make a 'scenery' folder within it. Place the stub BGL in there, and add 'Stubs' to the Scenery Library... moving it down beneath the default airports ( below '0000 base' ).

The stub then sets the future elevation for C59... which should be the same as my newly re-designed C59.

Look up stub using the forum's search function.

Thanks for the reply Dick.

I tried to write an xml file in the format you described but to be quite honest I have immense difficulty understanding the computer language and even though I wrote it as you suggested, just could not get it to work.

I did look up about "stubs" because I had never heard of this before and never had the problem when working on sceneries for FS9.

However I did manage to solve the issue by using ADE to design my airport and just following procedures I managed to get it to work with no difficulty. It may be another case of where Vista does not like certin programmes 100% on my pc.

Good that you are getting it working. For the record, the same need for a stub airport exists in FS9 when you attempt to change the default altitudes.

Hi Colin,

I think ADE will create a stub when you Change Altitude, and place it in the 'Scenery/World/scenery' folder... good to know if you ever want to distribute the airport, or if you need to delete the airport in the future.

ADE will indeed create a stub airport bgl file and also correct any altitude values for elements such as runways.
