Percy: Then you are saying that the A/T will attempt to maintain the MCP speed upon touchdown on a manual landing if no reverse is used?
I'm pretty sure Percy is saying that the A/T will not do anything (as your books say)
There are a couple of not-so-cheap desktop flight simulators on the market which model an active SPD mode during non-A/P coupled rollouts, but I would be more inclined to believe your FCOM.
