BOAC asked :
Air Data presented to the crew at the outset? [...]
Would the ASI's L and R now show a disagreement? [...]
Would the standby ASI be affected?
BOAC, your questions are all related to what the crew is being provided as
indications on their instrument panel. What I am dealing with is computerized
flight controls.
ASIs were affected. But there is no way I could discern exactly how and when. Inside my own subset of research in this, however, ADR data (provided to Flight Controls Computers -> the PRIMs) was affected. In Normal law, PRIMs could effect ultimate authority on flight control surfaces. There are 3 of them. What happens when PRIMs are in disagreement ? Now that is a question...
FDR might reveal some of these parameters. It is however unfortunate that ADR2 data and associated RHS airspeed was
not recorded on FDR...
