Shortfuel,
your post inspires me a question, silly maybe but still a question, something I've never thought experimenting in a simulator :
During automatic landing, the A/THR will go in RETARD mode, commanding IDLE thrust during the flare. But what would happen at the end of the landing roll when the crew disconnects AP in order to exit the active runway and, if despite the ''RETARD'' callout, the crew forgot the thrust levers in the CLB detent ?
My presumption would be that the engines would go to climb thrust ... ?
