The iniBuilds team continues to deliver on the promise of continuous improvements for its A350 airline on both Microsoft Flight Simulator 2020 and Microsoft Flight Simulator 2024. This update, version 1.0.8, brings enhancements to the step climb functionality, additional ECAM logic, and more.
The first area in the update post was all about the new step climb enhancements that are coming with the A350 Airliner. They said that you can now enter an increased number of step climbs manually or via the SimBrief import, along with the ability to combine it with auto step-climbs to ensure you fly as efficiently as possible (virtually, anyway).
It was also confirmed that the ELEC and FCTL ECAMs have had a “huge overhaul”, with support of a qualified A350 engineer looking over the new additions. The failure states have been reviewed, and associated system failures and redundancies have been added to the simulation. You can see all the new additional ECAMs below.

iniBuilds announced in their stream earlier this month that they intend on continuing to continue refining and improving the A350 Airliner. This includes free updates to feature the ULR variant, a new HUD, and much more.
The full changelog also indicates there are a range of fixes and updates to the plane on both platforms across the systems, artwork, and other quality of life improvements. You can see the full update below, and when you’re ready, you can update via the iniManager. If you haven’t picked up the A350 Airliner from iniBuilds, you can do so here.
Finally, for those waiting for it on Xbox will need to continue to wait as iniBuilds continue to test and optimise the experience on the console. As soon as more news is available, they will let us know.
