Who owns the airframes? Mil or contractor?
Why buy from 3 different manufacturers?
Why not go T6 and B200 King Air for better value or Super Tuc and Phenom?
120TP - is basically a PPL cruiser with a turboprop, aero strakes allover it and winglets. Still has poor Grob Tutor like design issues like very wide canopy arches, only available in hard to see white scheme and given large wingspan will be bumpy at low level. Martin baker at Farnborough 2012 said it could not be flown with 2 up and fuel.
SF260 TP same engine more useable!
Indian AF prefered the PC7 for similar money to 120TP
