No surprises here. None.
Whilst this screams repercussions of modern airline standards, it also screams louder of AI / AIE, as well as the DGCA. Pilots are not taught, instructed or evaluated to fly the aircraft at and within it's limits. Sim checks & procedures are ticked as completed when no such exercise(s) were completed.
Aviation academics now label pilots' abilities to hand fly an aircraft as "resilience", and it is now used to define standards at airlines as well (Flt Inlt a few weeks ago....). "Resilience"?? And to think the inability to pilot an aircraft in such a way as mentioned here, or as Capt make such rudimentary decisions was called "unemployed" or "fired" for being not up to standard.....
Re-training required? YES. Will it happen or will the poorly trained pilot be hung out to dry as a result of an airline's woeful and (criminally) negligent standards?? No. And then when we have another Mangalore it'll be: "Who saw this coming??"
