"Is there a perception among (AB) pilots that once TR(s) are deployed, a go-around is not possible?"
No, but there is guidance for ALL commercial jet pilots that it is unwise to attempt a go-around after thrust reverser deployment in case one of the reversers fails to stow. This follows a fatal B737 accident many years ago. However, I have initiated a go-around from the runway in an A320. Like any other manoeuvre in the A320 it worked a treat, just like it should on any other aircraft, despite the sound advice not to try it. I am making no comment on the rest of the content of this thread other than to say that, as usual, most of it is uninformed rubbish. I have 12,000 hours in command on Airbus A320/321, in all weathers, and from long and short runways, and the aircraft never let me down. I have no idea what happened in this accident, and I suggest we all wait for the inquiry results (forlorn hope)
