Hi Gryphon,
But the real problem is you and me "thinking" instead of providing references to docs.
I think that computers will be reset when engine shut down.
Please point out the "ENG MASTER" switch logic gate on the diagram.
Why do you think "GND Spoiler .... Disarm" is performed during After Landing Checks?
Why not simply keep them Armed ready for the next take off?
Maybe it is just a flow pattern and nothing else. Maybe not...
Do you really think Airbus just want to give us things to do and look busy during Flow Patterns?
