another T-6 Texan II (turboprop aircraft) question. When reading the airstart prodedure in the engine failure during flight section of the manual, I found something that Id appreciate the clarification. It mentions, "The higher the altitude, and the slower the airspeed, the warmer the starting ITT peak temperature."
By airspeed, I believe it is referring to KIAS (all graphs and useful data for pilots is in KIAS, at least in this manual) so no arguments there. now, we know that the higher the altitude the less dense air gets to keep up with a relatively constant KIAS, then TAS has to increase.
If TAS increased at this higher altitude, (relative to the air the plane is passing faster) and the plane is making up for the less dense air, why would we expect a higher peak ITT compared to an airstart at a lower altitude? Shoudnt be about the same peak temp?
Also the higher you go the colder it gets at least for a good 20,000 ft MSL which is a major portion of the flight envelope for this aircraft. (max ceiling 31,000 ft MSL). I guess getting colder air has zero impact on ITT? I appreciate the discussion. TY all!
