Flight YGR 11 has landed (with an update)

Written by martin published on July 14, 2025 in News

With a few weeks delay, iteration 11 of the Yeager game world has finally landed today. It comes with rather massive changes under the hood, a data patch and new aircraft trader personalities. You can read more on these things below, but if you just want to get going: Yeager XI is live here and to celebrate the occasion, credits are off 11% until the end of the week!

Yeager XI

The 11th iteration of this game world comes with pretty much unchanged settings compared to the previous one: Second-hand aircraft at launch, double slots and at most one holding per player. It will run until February next year, and it comes with all the updates introduced by today's patch, of course.

Update to version 6.11

As discussed before, the relaunch of Yeager was pushed back because I was working on some major upgrades to modernise AirlineSim's technical foundation in preparation of upcoming feature developments. These updates have now been completed and applied to all game worlds. While most of the changes should not be visible to players, the patch also brings a few changes that are. Most notably, there are a lot of updates to our airport database (thanks a lot, Koen!) and of course the changes to aircraft trader behaviour. For a full list of all the changes, including those that might be added over the coming days as I fix teething troubles of the new version, can be found on the forums.

Speaking of teething issues: Given the scope of the update, there are bound to be some. If you run into any issues or bugs, please don't hesitate to get in touch on the forums or on Discord!

New aircraft trader behaviour

Among the changes that made me push back the launch of Yeager was a change to how the official AirlineSim aircraft trader prices second-hand aircraft: Rather than just computing an initial price based on the linear depreciation of an aircraft, the trader will also take into account a value based on how long the aircraft has been on the market already. This value will typically be higher than the book value for older aircraft and will then fall off at a fixed daily rate.

To make things a bit more interesting, all game worlds now have more than just the single "Aircraft Trade and Leasing Organisation" that has existed before. All of them feature a slightly different "personalities" that determine how they might deviate from the baseline formula described above and at which point they give up and scrap an aircraft. We'll keep an eye on how these personalities work in practice and tweak them as we go.

What about Quimby?

Some of you might have noticed that another game world ended today: Quimby XVI. As I don't want to launch two game worlds on the same day, this relaunch will be postponed as well. I'll work out a new launch schedule and let you know as soon as I've got something concrete to talk about.

And with that: Have fun in Yeager (or any other game world) and let me know what you think of the changes!
