Thats good stuff Jim! I've been asking for that formula for years but the powers that be treat it like the secret of life or something. Any chance you could get the formulas for the other aircraft as well? AS350BA? EC120?
EC145?
I already made a excel sheet with it and it seems to work well. I have to double check it's accuracy but it looks to be spot on. If anyone would like it just send me a PM with your email and I'll send it to you but bear in mind it is "for reference ONLY!!" at this point as it has not been approved by the manufacturer.
Happy New Year!
