Bugg Smasher I repsectively disagree with your comments. It is true that the AT's start retarding based upon RA height of 47' as I recall. I assume you would have your hands on the thrust levers and either resist this movement if you were slow. The point is disconnecting the AT's at 50' simply does not put you in the energy loop. If you want them off, disconnect them well above the threshold, like maybe 1000' and fly the airplane to the touchdown.
Does your company use 35 flaps for all landings or do you use 50 most of the time?
