@Hamburt Spinkleman:
Correct - the important paragraph is on the following page:
In ALTN 2 the roll control is roll direct. In certain failure cases such as loss of VS 1g computation or loss of 2 ADR, the longitudinal static stability cannot be restored at low speed; in case of loss of 3 ADR it cannot be restored at high speed.
There's a reason that Alternate 2 is marked with a very clear "(NO PROT)" on the ECAM.
