Helo World- I had 700 USN hours and 500 H-60 hours before being allowed to make HAC, to give a baseline.
E-2s- 690 E-2 hours before making PC, and another 20 or so before CAPC.
Big difference is I did a shit ton of E-2 2P-2P flights, starting at probably about 600 E-2 hours. (E-2s have a 3P designation, but only carry two pilots.. Don't ask why, they don't know).
The E-2 NATOPS checks are the same for 3P/2P/PC/CAPC. Only different one is the "Super Stan" for ANIs/NIs.
Same for 60Bs as well.
I'm just not seeing the complexity difference in the P-3 over the E-2. Yeah, two more engines, and some accessory stuff on the motors is different. Pretty much a mechanical flight control plane? Check. Complicated as fuck FOUO procedures? Check. All sorts of evil shit the props can do to you? Even more with the NP2K.
Just not seeing the need for the P3 3P to be a borderline functional wing leveler, vice a pilot who would be more than likely OK if the PPC died of a massive heart attack in either seat.
