As someone who spent a great deal of time both flying under the Indian FDTL and analyzing its impact on operations I can say unequivocally that it was one of the most screwed up pieces of regulation to ever see the light of day.
One of it's many mysteries made it possible in some instances to continue towards further time zone displacement with 1/4 of the rest that was required before one could turn around and head for home. It was both operationally insane and completely contrary to what is known about the management of fatigue resulting from long-haul flying and time zone dislocation. I will not miss it for a second.
Having said that, the fact that the DGCA would place the entire regulation "in abeyance" without promulgating a replacement FDTL effectively leaving the country without any set of rules at all is amazing and yet entirely consistent with the quality of the now abandoned first attempt.
