Inquiring mind

ALT LAW 2 was because of a failure of the speed measurement, detected by the aircraft systems. How would a protection based on speed then be active?
High speed stability IS still available with only 1 functional ADR (i.e. 2 ADR's on the 'fritz') in ALT2.

MacMillan told me.

In the incident under discussion, the 'plumbing' caused temporary problems with all 3 ADR's, which 'latched' ALT 2...

When an ADR is recovered, is high speed stability regained?

If 2 ADR's are recovered, is low speed stability regained?

Is VLS redisplayed?

A little help here on the academic side only, please...
