Namaste CRAN.........in the AS305B3e (H125) @ ISA +25º above 22,000' You don't have HOGE, barely HIGE with 2 x POB + 50kgs GoJuice + 25kgs stuff, available power is 40% torque if Your lucky....yikes your damn limited! Plus Your up against the Power pedal bump stop

so a double whammy
So with power; just like a 269, 22 or G2 at sealevel same damn problem

So the power margin limitation problems are exactly the same

manage what You have wisely
Happy landings
