It seems that they can, but I really don't understand how the flight control logic let this happen.
74 KIAS? 33deg of AoA? 43.6deg of roll?
H.A.L.L was not supposed to allow this.
And I don't understand how they managed to keep the sink rate below 4000fpm in that condition.
One minute later gusts with winds up to 14 knots from 340 degrees were recorded at the aerodrome, at about the same time the aircraft just intercepted the localizer runway 03 at 2140 feet MSL with automation, autopilot and autothrust, engaged, however, the indicated airspeed began to decay and the attitude began to gradually increase. When the indicated airspeed decreased through 114 knots (Vapp 126 knots) an automated "SPEED" warning was triggered. A target speed of 131 KIAS was selected into the speed window of the flight control unit. Autothrust began to accelerate the engines slowly, however, speed was already decreasing at 7 knots per second, the autopilot automatically disconnected, the Alpha Protection function activated. Alpha Floor activated when the speed reached 83 KIAS, the aircraft reached a minimum speed of 74 KIAS before the aircraft began to accelerate again, the maximum angle of attack was 33.4 degrees together with right roll and loss of altitude. The aircraft reached 43.6 degrees right roll, 3924 feet rate of descent, the EGPWS sounded "Glideslope", "PULL UP" and "SINKRATE" in sequence. As the aircraft lost altitude and gradually increased speed, the crew, now manually controlling the aircraft now with flight augmentation computers 1 and 2 inoperative, gradually regained control of the aircraft, arrested the descent at 884 feet MSL and began to climb the aircraft again.
