There was a qualified pilot in one of the seats at all times and it only happened during cruise.Personally,I'd sack the rat and tell the training Captain not to do it again but thats just me.I know there are a lot of pencil pushers out there in aviation who just love to get caught up in minutiae.
The DGCA needs to fry bigger fish,like making sure theres complete transparency in the way they operate and investigate accidents,that airlines have enough crews so that FTDL's arent broken,and re-thinking the no TAKEOFF/LAND policy for co-pilots because those co-pilots are second-in-command and if the Captain becomes incapacitated,they must know how to land the plane!Train the co-pilots in SOP's and AFDS operation by all means but also ensure they know how to fly the plane.It might save lives one day.
