That was what I was trying to get at - you make control inputs to manage the flight path - keep the aircraft on glide and centreline
The case for any aircraft, yes? And I agree, JW, we seem to share an understanding here.

while the FBW does the donkey work of keeping the roll/pitch attitude you have commanded...
Nice as it is, the FBW is not always quick enough to restore a previously commanded attitude, particularly on approach with gusting or variable winds. Countering the gusts is a mostly a manual affair.

...to maintain your desired path.
Yes...meanwhile drift is occurring, hence the sidestick gyrations that can border on PIO. (your reference to pot stirring)

As I understand it, due to how the FBW is programmed for rate and G, control input deflection and timing will be at odds with what worked previously on a conventionally controlled aircraft. It takes practice in the actual aircraft to get 'in sync'. Sim fidelity is not adequate, in my experience.
