A whole lot of posturing by the DGCA (what's new).
This requirement has been around for a long long time. But asking airlines to put a time frame on expats' tenures is flirting with danger. You can't rush the development of student pilots/first officers by mandating strict limits for expat contracts. This has to be done at a reasonable pace with no external pressures.
You can kick and scream all you want but expats are here to stay.
Airlines have to get back shortly with their replies. And if they don't, we have ways to make them comply.
Sheds some light on their mentality.
