why itt limit higher with higher oat?
Hi Guys,
I have a question about the ITT limits of a turbine eng, specifically the pw125b.
For 'GA' power, there is a flat limit (800).
For 'TO' (normal) power, there is a variable limit, below 800. (It's flat up to a certain temp, goes up, and is flat again.)
That limit is lower with lower temps, and higher with higher temps.
I understand that is is lower for TO compared to GA, but why does it go UP with higher temps?
Does that have to do with air density? does the ITT not go up as much with higher temps as opposed to lower temps on higher temps?
Cheers,
LB.
