Airport CEO Beta 8 released

Hello there, airport CEO!

We’re less than one week away from the 1.0 release of Airport CEO and in anticipation of this event we are now rolling out the last default beta version, beta 8! This is another update with extended focus on balancing, performance improvements and some additional bug fixes but also a few new minor features that we’ve deemed crucial to be part of the 1.0 release.

On Thursday at 19:00 CET, Airport CEO will transition out of early access together with the previously announced minor 1.0 celebration surprise. We’ll also include a short 1.0 release letter reflecting on the journey that has been and what’s next for ACEO and the studio moving forward.

We’ve seen a significant decrease in bug reports over the few last week and especially bugs of critical nature such as stalling persons or pathfinding, graphical glitches or crash events - if you are still experiencing any of these issues on a regular basis we ask that you do not only bug report them but reach out with us directly on so that we can assist you in expediting the issues.

Update notes

Road node restrictions

Roads can now be restricted to certain vehicle types through a right click option, similar to how you set specific rules for taxiways. Public roads can be restricted for its most common vehicles such as person cars, taxis and buses while service roads can be restricted by its service vehicle types. For example, you can now by right clicking on public roads restrict access to that road by defining taxis as the only allowed vehicle types, while via service roads you can now seal off areas to only cater for service trucks.

Schengen rules

By default, Schengen rules ow apply for flight generation across Europe. This is in response to bug reports concering a lack of flights in certain airport size cases for countries across Europe. Going forawrd with the default Schengen setting, flight generation across airports that are placed in Europe should be significantly imrpvoed.

And yes… as usual… loads of bug fixes and balancing!

This update too, like its previous predecessors contains a good amount of fixes, balancing and most notably performance improvements. We’ve made multiple changes to system that in specific cases have had a significant performance impact of airport layouts that diff compared to the norm and will continue to keep these types of reports under close consideration.

See you all on Thursday!

Attention! As part of this release we’ve as you can see finalized all remaining MDKs and uploaded them to the folder. Read more about airline modding with MDKs here: Airport CEO | Modding


Great work Apoapsis! Looking forward to 1.0 release. You have made a great and enjoyable game to play!

Not sure if it’s related to ‘[ACEO-41520] - Added better compression for mod textures to decrease RAM and VRAM footprint’ but modded airlines that worked in Beta 7 are now rendering with invisible fuselages in Beta 8.
Apologies for opening bug report but the number disappeared when I alt tabbed out.


Oh my god! Now that’s BUGGED.

For some reason it’s called Experimental :rofl:


There is a massive bug: Night construction illumination is causing a lot lag. There is no lag during day and during night when I don’t construct things.

There are 2 general bugs that I can’t report via Bug Report system:

  1. Realistic International Stands explanation is not fitting into the screen:

  1. Staff information card is confusing. I don’t know if full Bladder bar is a good thing or empty Bladder bar is a good thing. Same for energy and performance. I think on these 3 bars; red means something bad and green means something good no matter filled or not.

Not sure what you mean in the second picture. If the bar is filled, it means the need is satisfied or that the skill/productivity is high. If you find the bars confusing, just look at the colours.

Yeah and that needs to be more certain for new players. Like bladder is “if bladder bar is full, staff needs to go to bathroom” or “if bladder bar is full, staff went to bathroom and satisfied himself”

As the Beta phase is coming to an end, can i still expect longer runways at all? Someone in another post said this would probably happen after map size was increased, so i kept expecting… But i’m losing hope already

Sorry, but I disagree. I think the colours make it easy to understand for new players, and I haven’t seen any complaints besides yours.

ACEO-41559 Modded aircraft look terrible in Beta 8. All graphics settings are the same. Tried it with and without the VRAM setting as well.

Screenshot 2: Beta 7 Default

Yes, I thought so too the was a distinct lowering of the quality. Logos too.


I agree, logos look terrible in Beta 8.


great job

I went to adjust the Graphics Level and now its jumping between fast, simple, good, and hight and giving me the spinning ball of death between each and I cannot get out of it or save it. The slider keeps moving up and down. it doesn’t stay on one option.

Trying to adjust it in game main menu before I load the airport and its doing the same thing. jumping around. I cannot get it to sick on one option let alone the option I want

Hope it gets fixed soon

Just noticed this. I did Planning build of foundation for the terminal on the right then saved and exited the game and then loaded back in and did planning tool of foundation for the terminal on the left. but now its brighter than the rest? is this suppose to be?

[ACEO-41540 2] - Restricted small check-in desks to only handle check-in of small flights (due to now allowing check-in despite baggage handling being enabled)

This causes an issue with the tutorial. Right now, it asks you to build a medium stand in Step 1 of the International Airport Tutorial, but passengers can’t board any flights on that stand until you get to Step 3 where you research baggage handling, which unlocks medium check-in desks.


We’ll add a graphics setting for the texture compression! :slight_smile:

Did you bug report this?
