Romeo E.T. You're wrong, the A/T will still retard on a single channel approach. I've had it several times on a windy day when I've been hand flying with the A/T in arm mode. The speed floor has been triggered by a gust and the A/T has gone back to MCP Speed, and at 27' or so I have seen retard annunciate and the thrust levers retard.
Actually, an alarm triggered by the speed dropping more than 20kts below the MCP commanded speed would be a good idea.
But someone should have spotted this, and even a new pilot should know the standard stall recovery - they must have practised it in the sim recently.
