Just looking at the pull to high hover and no droop in rotor, I know a hundred pilots that could have walzed that aircraft outta there. But it would take skill and some finesse, and understanding of the FADEC. A couple seconds at blowaway are nothing when you can accumulate 10 minutes in the life of the engine, though unlikely you'd even get to blowaway if you used that droop to accelerate instead of trying for an HOGE that isn't going to happen.
In our PC1 world we forget what aircraft can do PC3. The takeoff limitations in the RFM are based on 150fpm OEI, that's all. We'd wrestle overloaded 76A models in Africa, Iran, SE Asia, Australia where all we would get was a couple feet hover and could only dream of how high this guy was holding it up. The C++ is pretty good at high temps, and the FADEC is biased to account for it. Anyway, you can always substitute skill and finesse with regulation and make everyone buy 139's and operate them at less than 6000kg.
