Hi HN,
Thank you for pointing that for clarification. This is what I meant by specifying the Law related to each. VAlpha_prot (Normal) is replaced by VStall_warning (VSw) in Alternate... But, it should never be displayed on the PFD if the change of Law is due to an UAS event. Instead, there is a flag -SPEED LIMIT- meaning that the limits (high an low) are lost.
