Hi Guys,
I'm afraid my figures are right, I have my Ipad next to me as I answer your suggestions.
Uplinker, I agree for derate but disagree for ATM as it reduces power from the derate, so derate is the smaller engine (24K => 94.6%) and then you ATM from 24k, (R24K 31°C => 93.4%),
if ATM was from full power it would be a higher %.
wiedehopf, I confirm what I said, R24K
Engine inop go distance = 2165M
All engine go distance = 2210M
New_era
Full 26K is 98.9%
Engine inop go 2625M
asdr 1931M
All engine go 1829M
Full 22K is not allowed with current conditions
