Yup same issue here with the MD-82.
Can also add GSX Pro Services remote control to that list as while sometimes the MD-82 loads, the GSX menu just outright doesnāt appear in the MD-82 tablet aircraft services EFB.
Whilst SU4 seems to have addressed the see-through cockpit (LOD?) issue that was introduced in SU3, it now seems to have rendered the A350 unusable, in my view.
On my PC (high-end), I am told that all of the batteries are off, one engineās master switch is off and unsurprisingly, that that engine has low oil pressure.
I donāt think the LOD issue is completely resolved either, since lettering on some of the buttons can disappear either when I zoom out (not excessively) in 2D, or when I move back a little in VR. This seems to apply on all airliners.
As your post was merged here, I assume you found the solution to your issue?
If not, here again:
A known WASM bug is causing this. Fortunately it can easily be corrected until there is a fix. Just go to the maintenance menu in the EFB and replace batteries, service the engine, etc.
And your A350 is good to go.
Bit if you are using Navigraph, be aware that WASM bug also blocks the navdata update - it will hang.
Unfortunately this can only be solved for now by switching to the Sim default navdata on the EFB.
Else the A350 seems to work quite well. Had more than 20 hours with it in SU4.
Thanks for your help with this - much appreciated!
