iniBuilds A350 V1.2.4 released

iniBuilds A350 Airliner V1.2.4 Update 🚀

v1.2.4 for the iniBuilds A350 Airliner is now available. This update resolves several key flight logic and navigation issues, including incorrect descent mode behaviour, overlapping step climbs on the position report page, and inaccurate fuel burn predictions. Fixes have also been made to premature auto-rotation, incorrect DME/VOR display, and unrealistic ADS-B vertical speed readings, alongside refined roll sensitivity for improved handling.

An EFB update also introduces an in-flight maintenance override, allowing users to repair items during flight.

This update can be downloaded via the iniManager.

Thanks, @MrLamb.

I plan to bypass the v1.2.3 and test this v1.2.4 instead, when I can.

Cheers…!

Well that didn't take long. Might as well call this a hotfix.

I just had my first WASM crash in over 8 months with the A350. Five steps backwards, again.

Don’t just update it.  Delete it, remove left overs from community and all MSFS folders and fresh install.

That; what I do. I never update. just uninstall and reinstall and a reboot. No wasm incidents so far.

Yes. Myself being on Xbox/Marketplace, I recall that I never actually see an option to update this product in My Library (from the previous version), as is customary for other products.

So, basically, I always (have to) re-install the latest version (directly) from the Marketplace every time.

Maybe that’s the reason, I’ve encountered WASM errors, rarely ever…not sure…

Cheers…!

@Tuskin38

I do recall, you have been one of those fortunate A350 users on the PC, immune to WASM (those orange-colored flight deck screens still give me a bit of nightmare…🙂…)…

Hope, a fresh install and clearing of the community folder etc. gets you back in the pilot’s seat of this one..

Why are WASM crashes so common in flight simulator now?

One possible reason could be that WebAssembly is ideally suited to hiding DRM measures – that is, 'tunneling' the relevant code. I'd bet there's a lot of experimentation going on in this area.

'It is better to be silent and be thought a fool than to speak and remove all doubt.'

Yes, clearly, something new (experimental?) has been going on since late 2025 and in early 2026, in MSFS.

That’s why the WASM reports have lately proliferated, especially for some airliners, that were (mostly) immune to it before.

Also, I understand that the (now well-known) “Orange” WASM screen notification was introduced as an added diagnostic tool, in SU4. So, the WASM was present earlier too…

A350 2020 users were also getting WASM crashes.

Just finished OMAA-YSSY in real time, no issues.
