An interesting article in Flight International recently, commented on airbus making changes to the FD logic to cater for slow speed flight with Auto thrust off. Airbus does not recommend flying in mixed modes e.g. Auto thrust off and FDs on. The article said, in wake of numerous Alpha floor protections activating resulting from crews not monitoring speed and with the A/T off, they are thinking of changing the logic of the FDs to remove them as speed decays below a certain point, because at present they indicate higher pitch to maintain Altitude, and certain crews are merely following the FD's blindly.
