Follow up on the steering:
Ground mode is a direct relationship between sidestick deflection and elevator deflection, without auto trim. [FCOM DSC 27-20-10-20 A]
For roll control during take-off, the transition from Ground Mode blends into to Flight Mode (full FWB magic) over 0,5 seconds after the pitch reaches 8 degrees N.U. Thus anything afer 20:40:34 is roll demand control of the FBW - assuming it is what it actually does (pitch normal law is most certainly not a simple 1g command as the FCOM explains).
More observations:
+ despite full and dual R sidesticks, the aileron deflection is not maximized after Flight Mode becomes active. At 20:40:35 this is understandable, as the roll 1st derivation (not charted) peaks with reversal of the bank. Inbetween secon d 34-35 it is bit more confusing. Maybe the effect of absolute symmetrical deflection being reduced due to tkof aileron droop?
+ seconds 39-40 the aileron displacement is not symmetrical
+ we don't know the impact moment. Assuming it happened at recorded max bank is not correct.
