The right question would be..what was the Pilot Monitoring doing? For all we know the F/O might be the Pilot flying.
Pilot Flying .. Pilot Monitoring !! ... in Air India ?? hahaha good joke !
I know the work culture only too well in that airline.
PF, PM, Captain, First Officer etc roles exist only on paper.
In reality, in Air India operating procedures, you have the following two crew members :
1. Boss or King (who sits on left seat)
2. Servant or Slave (who sits on right seat and carries captain's flight bag when not in air)
