What would the a/c be doing after STALLSTALL? Would she be attempting to ND the airframe? With elevator? Then PF counters with NU? expressed in TRIM (THS). What does the Protection do, here? What does she do when Overspeed protection quarrels with STALLSTALL? Did PF get between duelling Protections?
Was this a battle between two stubborn inputs, one Elevators and the other THS? Did PF eventually "Win" when his surface overcame the a/c's? By that time was it too late to recover the NOSE? Not even with Manual Trim?
