MSFS20 Sim Update 16 Compatibility

August 5, 2025|

With today’s public release of SU16 for MSFS 2020, I have been reviewing ESD addons for compatibility. With 2024’s new aerials and elevations being backported, a handful of addons need to be updated. Mostly some of my older freeware. All but two payware addons have held up OK. Seven freewares need varying levels of fixes and cleanup.

I have put together a list of my affected Freeware and Payware addons, with some details on what needs to be done. Anything not mentioned seems to have survived SU16, or at least I didn’t notice any SU16-specific issues.

Affected Payware Addons

Chunilna Cabin Strip: Runway is OK. Along the creek needs to be updated for new aerial imagery and terrain elevations. I have been expecting these issues as I already had to go through this for the 2024 native version. Because the 2024 native version needed to be released earlier on, and the changes couldn’t be made to the 2020 version first, this update will be a bit more complex and might take a bit of time to sort out. A lot of data needs to be manually backported and checked, depending on how I decide to approach the update.
[Updated] Bald Eagle Airfield- Myakka Head: Runways are OK. Needs excludes for new road overlays and Transmission towers.

Affected Freeware Addons

[Updated] Stampede: Needs update to fix major elevation issues (runway sunk into ground).
[Updated] Kantishna: Needs update to fix major elevation issues (runway sunk into ground).
[Updated] Rangeview: Runways are OK. Needs some cleanup for autogen vegetation, roads, and some water polys.
[Updated] Montana Creek: Runway is OK. Needs some tweaks for autogen vegetation and models need to be moved to match new aerial imagery.
[Updated] Davidson: Minor issues. Runway is OK. Needs some tweaks for new autogen houses.
[Updated] Fantasy of Flight: Runways are OK. Terraforming issues on TIN are greatly improved! Some minor terraforming issues that need to be looked into.
[Updated] Bowman’s Beach Helistop: Just needs a building exclude. Maybe some minor tweaks, but in good shape otherwise.

It’s always possible I might have missed an issue during testing, as it’s a lot to look over in one sitting. If you experience any issues not listed, be sure to drop me a bug report on Discord or through the contact form here on the website so that it can be investigated!

MSFS 2024 Native Updates

Now that SU16 has been released and aerial and elevation data is synced up between both sims, I will be looking at doing 2024 native conversions of my freeware on a case-per-case basis. This will be done after the 2020 issues above have been addressed. This not only makes the transition to 2024 native much easier, but it will allow me to better gauge what I need to prioritize. Not all addons may necessarily need to be made native right away, as there may not be any real benefit after their 2020 updates.

Stay tuned for a stream of updates coming soon!
