WSSS: I truly doubt that FBW had anything to do with this incident.
"We all know how easy it is to recover from a stall. All pilots learn that before they are released for their first solo. You learn stall recovery in the first 10 hours of your PPL flight training."
Many argue that "true flying skills" are no longer present in today's younger pilots due to FBW and the video game mindset.
I believe that the problem is more the fact that since the days of the 727, the concept of the "coffin corner" is no longer taught. You can't just climb as aggressively in the thin air as you can at a lower altitude without stalling.
A stall in PPL training with a fat wing, in fat air is an easy fix. Max power, lower the nose some. And you are never trained in full stalls again.
I was trained in the jet only the "approach to stall recovery",
It wasn't till several of our company aircraft entered moderate stalls at high altitude that that they trained us in the proper recovery.
I was shocked at the altitude loss and pitch attitude required for recovery.
And still, few airlines teach this in the sim.
