Hi CONF iture,
Apparently value and time constraints have been exceeded long enough to command the AP and A/THR to quit and the FCS to switch to a bizarre ALTN LAW but not to announce the reason why, be it NAV ADR DISAGREE ... !?
Correct, AFS = Δ 20kts 425ms, apparently they don't want the 'logical but with lack of intelligence' AP to make inappropriate actions.
EFCS ALTN = Δ 30kts 1s compared to median @ T-1, latched > Δ 50kts after 10s compared to median @ T-11
No bizarre ALTN LAW, THE only ALTN LAW (PROT LOST) as it is announced.
PROT LOST = NO protections.
The 'reason why’ AP dropped off and EFCS reverted to ALTN LAW was direct in view,
on the PFDs, different speed displays / flagged SPD and SPD LIM in capitals, bold and red.
