Thanks VA- But not sure we are on the same page. De-selecting the A/T puts the system into ARM mode, meaning it does not control the thrust UNLESS it reverts to SPD due to "ALPHA FLOOR" (Which is really min-speed)
I do have the reference in the FCTM which seems to not recommend using ARM mode, and will raise this with management- just wondered if anyone else had a Boeing reference that discouraged the practice.
