PHHL does have expat Pilots, yes GVHL is hiring but only if you have 1,500+ hours Rotory, 100 PIC on AS350 type & 100 hours slinging. Instrument rating is NOT required at all as 99% on-shore work is all done dayVFR, it gets you your Special VFR rating a bit faster, hence a take off approval outside of VFR minima & pay increase for same. Aerial work is rapidly growing especial power-line stuff. As for industry boom; yep, it sure is booming, heaps of new machines coming into the country especially R44's(scary) & AS350's which will soon overtake B407's. Should have seen the pilgrimage flying this year to Amarnat, Kedarnath & Hemkunt wow, yes booming, at Phata 4 - 5 machines doing 5 hours each per day, so yes industry is buoyant.....Happy landings
