Local and gaijin pilots on the flight deck might make for better comms between pilots and CA's, however, what about the potential lack of undestanding between the pilots in that scenario.
Can be a big problem, believe me. Add an emergency and look out, single pilot here we come.
Safety could be improved dramatically if they only mixed crews for the required check flights etc.
Wishful thinking really, as nothing ever changes in this part of the world.
Just love that raw fish.
