The beta journey of the next major X-Plane 12 patch continues with a second iteration, focusing on improving on the first build from a few weeks ago.
The patch, which is numbered 12.4.0 and is nicknamed “C-Check Update,” is supposed to bring a nice round of overall polish to the simulator by Laminar Research, on top of significantly improving the default Airbus A330.
And the second beta iteration indeed improves the A330 further, on top of bringing a plethora of fixes to improve the experience.
You can find the full patch notes below.

You should keep that this is a beta patch, so it’s designed for testing and not to offer an optimal simulation experience. Download it at your own risk.
At the moment, we don’t have any information on when the patch will be officially released, nor about how many beta builds there will be before that happens.
X-Plane 12 is currently available for PC.
