Farlis

Have you checked your oil quantity during preflight? The aircraft will use oil and hydraulic fuel whether you have failures activated or not. You have to refill both every once in a while.

If you clear the WASM folder it will rebuild it. And that takes time. A lot, depending on your system. But you can expect 20 Minutes or more. But this is only on the first load of each model.

This is not an A350 problem it is an Asobo Problem. This bug also happens in the default EFB. I'm not sure what causes it but apparently the API that calls the charts gets unresponsive and that is something Asobo needs to fix, not IniBuilds.

You confuse this with the FBW A380 or maybe the A400M.

The A350 has no manual flare mode.

Do you use the Navigraph AIRAC for the base sim installable through the Navigraph Hub? If so, deinstall it and try again.
