Thanks FCS Explorer
Could you tell me what happen in this other scenario?
MCP alt window = 3000, ALT HOLD mode is engage
MCP alt window changed to 1000 feet, VS mode engaged (we are descending to the new altitude selected on the MCP)
Crossing 2000 feet we changed the MCP alt window to 3000 feet again.
What will happen?
Will the FMA go to ALT HOLD at 2000 feet?
or
Will it continue the descent in VS mode without altitude restriction?

Thanks
Alejandro
