so, this guy had it engraved is his mind that with the fly-by-wire system working properly, he could NOT stall the airplane NO MATTER HOW FAR HE PULLED BACK ON THE STICK because the airplanes computer WOULD NOT let it stall, correct? In this case, the fly-by-wire system was NOT working the way it normally would because of the airspeed malfunctions, correct? So, since he did NOT know that the system was not operating the way it usually did, he thought it was impossible the stall the airplane . So, if I understand everything right, the FO did the RIGHT thing with the information that he had. Correct me if I am wrong.
