I summarize:
- Airbus aircraft provide a g-load command for the pitch axis and a roll rate for the roll axis.
- The Airbus fly-by-wire flight control system compensates altitude excursions during turns.
- Thus, an Airbus pilot only has to concentrate on / control one axis during turns and can operate both axes separately – in most situations.
- From an ergonomics perspective operating only one axis is easier than two axes à the Airbus fbw approach provides reduced taskloads for pilots while manual flight.
- This is not about the incapacity of two-dimensional imputs, however, this support might erode “two-dimensional-input-skills”.
