The Indigo flight 6 E – 1763 had a loss of its hydraulic green system. That was the reason  for it’s return.  A full emergency  was declared for it’s return. It was declared at 7:22 am approximately an hour after it’s take off. For necessary maintenance the aircraft had to be returned.  “An alternate aircraft was provided to passengers for the flight to Phuket,” it said.
