Erroneous response?
In post #14 I wrote that an A320 will not stall when the high-angle-of-attack protection (alphaprot) of FBW system is triggered by an upward gust.
An Emergency Airworthiness Directive was recently issued in response to an occurrence where an Airbus A321 aeroplane encountered a blockage of two Angle of Attack (AoA) probes during climb, leading to activation of the Alpha Protection (Alpha Prot) while the Mach number increased. The EAD requires amendment of the applicable AFM to advise the flightcrew of emergency procedures for abnormal Alpha Prot. The new procedure starts with:
“At any time, with a speed above VLS, if the aircraft goes to a continuous nose down pitch rate that cannot be stopped with backward sidestick inputs, immediately:
Keep on one ADR
Turn off two ADRs”.
Suppose the event mentioned in post #14 occurs, and is erroneously associated with the new emergency procedure introduced by the EAD. Would switching off two ADRs reconfigure the FCS to Alternate Law, and the high-angle-of-attack protection would be lost?
