Has anyone else noticed in the A320, that when selecting F-FULL which generally occurs at about 1200ft AGL, there is ~1.0 deg (or more) pitch up? This means that, when hand-flying an approach and to remain on the required vertical path, a counter-action is required by the PF.
If AP is engaged with FPA -x.x (say -3.0) for vertical guidance, then after F-FULL selected, the FPA needs to be adjusted to -4.0 to retain the correct vertical path. This would be an increase in work-load particularly approaching the 1000ft stabile approach criteria, not experienced with F-3 approaches.
Quote: It is a bit paradoxical in Airbus that Flap3 gives better performance in wind sheer but Flap full gives better handling in turbulence. It's due reduced gain in flaps full. Controls are more sensitive in Flap3.
Can someone provide the reference to the FBW architecture for reduced gain in F-FULL, which would make F-FULL
less sensitive than F-3? From my experience, F-3 gives better handling and response in turbulence, than using F-FULL (less drag with F-3).
