It does not mention temperature, either ambient or ITT. If 'not always' then why a blanket 3%
A head scratcher for me too this one. If it was an ITT / OAT combo then it wouldn't always be 3% - TO distance would increase as a variable of the ITT limited power output.
UTD - just read yours. Can't think of any other reason, sounds plausible to me
Assuming not being temp limited, to achieve the same torque with IPS on you will have to push the power lever further. One effect I can think of is increased spool up time, although might be a very small effect.
With regards to power lever controlling target Ng, how come when I push it forward more it stays and never goes above 96% on a certain PT6 I've flown?
