Is this concept not the basis for Performance Class 2? Fly the CAT A profile without the weight restriction? Pardon my ignorance on the subject as we don't have a Performance Class 2 counterpart on the FAA side. I was told it was keeping the exposure time to a minimum. My only time playing wth the profiles in in an EC135P2+ and it does well at sealevel with OEI at all stages. Thanks...
