I think 792P would be the correct N number. SASless may be slightly dyslexic.
Some people like flatter approaches, some like steeper. Having seen the results of flat approaches over the years, I prefer steeper. I wasn't present on this approach, so I have no idea what the approach angle was. I do know that this isn't the first time a PHI S76 has put the main gear in the fence, though. Power was not likely the problem in this case. The S76A++ has the engines of a C, but the max gross weight of an A, and thus lots of power available. It may have the best power/weight ratio of any S76 variant, and I've never come close to running out of power in one, even in the summer.
