• 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.

MSFS20 Bumpy Runways

I have used ADE-20 to create several airports. The airports that have elevations that are different from one end of the runway to the other end have invisible bumps that can cause the aircraft to crash on takeoff or landing. Adding a flatten around the entire airport at any elevation does not fix the problem. An example is KBHM; if you simply create a project and build it, then you try to take off on runway 24 with a GA aircraft, you will encounter these bumps as you cross runway 18/36. If you do the same thing with the stock airport it is mostly smooth all the way from one end to the other. In addition if you add a flatten polygon around the entire airport with elevation set at altitude 184, the approach lights are visible for runway 6. However if you set the elevation of the flatten to something like 190 (halfway between the elevation of each end) the approach lights for runway 6 are no longer visible but are in fact below the terrain surface. I have had this problem with KRDU and KGSO as well. There seems to be nothing that I can do to remove these invisible bumps.

I most likely used ADE-20 to create the airport. I just created a test project of KBHM from stock using ADE-21. Now the runway doesn't have the invisible bumps except the minor ones that are in the stock airport. That means that I created KBHM using ADE-20 which created the bumps during the import. Now I have a monumental task of redoing all the work that I have done to create the airport along with the other two. If anyone has an idea of how I can fix this quickly I would appreciate it. I tried to copy the runways from the ADE-21 version back to the ADE-20 project and got an error message that I would have to change the runway numbers; can't do that! I have done this previously by copying everything from the older one to the newer one but the process and alignment can take days of work.

I had this problem with KGSO so I decided to see if I could rebuild it after the rebuild of KBHM was successful. I created a project from stock using ADE Alpha 21, made some corrections to the runway approach lighting, and did a build with no other changes. I did a high speed run on RWY 32, that had the invisible bump, all the way to the RWY 14 end without a problem. Then I tried the same on RWY 5L/23R and again no problem. Then I tried the run from 23L down to 5R and encountered a large invisible bump just before I reached the 5R touchdown marker. I removed KBHM from the Community folder and reran the run from 23L down to 5R on the stock airport and encountered the same large invisible bump in the same spot just before I reached the 5R touchdown marker. This was an issue that I was able to fix using a flatten covering that area of the runway with altitude 274.32, Falloff 100 and Flatten set to true. I don't know why the bump that is just past the touchdown point on RWY 32 is not in the Stock airport; nor do I understand why I can't seem to fix that bump the same way I fixed the other one. This seems to be more of an issue with the SDK or the stock airport than ADE. I am going to try to do the fix to RWY 32 one more time. BTW: the stock airport is a real mess and took me many days of trial and error to get to the point that I have today.

BTW: Tried the same fix again for for RWY 32 with the exact same parameters as the one for 5L/23R and it still doesn't work. I am not using the most current SDK, I think that I am one version back. Should I update to the latest?

Generally you need to use the most recent SDK since Asobo may make changes to the schema (rules for what is in an XML source File) and the compilers. For example since compilers are now included in the sim itself they can (and have) get changed and the SDK not.
 
I had this issue with YGRL which I started in ADE (2Way) - a rather simple regional airport. This airport has a huge dip in the middle of the runway and the whole runway placed down in a 'dip' that ran its full length and nothing seemed to remove it. In both ADE or DEV, adding a poly and terraform didn't help - it just messed the whole airport area(s) until I found this which corrects it.... Jon, assume ADE doesn't have a reciprocal?
On the runway you need to add/flatten points to change the runway and not the surrounding area. Lifting/flattening only affects the runway itself. Not sure where it holds the actual 'numbers' for where it applies in ADE. You can see I had to lift the runway significantly to flatten. You can add points at places and just lift that point. I wanted to raise the whole runway higher than the surrounding area. This is the terraforming property under the runway itself - clicking the Profile Editor.
