If the airbus doesn't have a stick shaker, then how are the pilots warned of a stall?
Stall speed can be less than 100 kt, so you weren't anywhere near it. And LTV gives you groundspeed anyway, not IAS, so I wouldn't go shooting approaches off it. Or making assumptions of pilot technique from it.
Anyway, there are other ways to keep out of a high alpha regime without a shaker. The Airbus has a number of protections built in, so the pilot can pull full back on the stick and get maximum performance without approaching a stall. Simply put, the pilot can't stall the airplane, since he can't reach an alpha high enough to stall. If for some reason alpha gets high enough to approach a stall, the autothrust system commands TOGA thrust to power out of an impending stall. If some flight computers or some combination of required sensors are inop, the pilot actually can pitch into a stall by overriding a preemptive pitch down command by the remaining flight computers, but in that case an imminent stall warning screams at him first. In really degraded operation, he doesn't get a pitch down command, but he does get the scream. The recovery procedure is as you'd expect: TOGA thrust and adjust pitch to stay out of a stall.
