Of course the Osprey is a 'fixed wing, multi'... just the engines move....
Technically, the MV-22 is in the Powered-lift category, it is not a fixed wing multi- engine Airplane. Singlne engine in an Osprey does not mean asymetric thrust like a normal KingAir, 737, or G5. That kind of situation in the Osprey (i.e. lose a motor
and the interconnecting shaft shears) results in departing controlled flight, or so I've been told by the Marine buddies I used to work with. Here are the definitions from FAR Part 1:
Powered-lift means a heavier-than-air aircraft capable of vertical takeoff, vertical landing, and low speed flight that depends principally on engine-driven lift devices or engine thrust for lift during these flight regimes and on nonrotating airfoil(s) for lift during horizontal flight.
Airplane means an engine-driven fixed-wing aircraft heavier than air, that is supported in flight by the dynamic reaction of the air against its wings.
As others pointed out, MV-22 should count toward the 2500 hr total. How much actual fixed wing multi-engine
airplane time do you have? If over 500 hrs, then it looks like from your profile you meet the rest of the mins. Send in the resume and see what they say. Don't waste another minute here!
Best of luck,
