porterprat ... the -42a pt6 has an itt redline of 800deg with everyday cruise settings of 740 or similar .
your recommendation of cruising in the 425/430 deg itt range instead of 460 is such massive of the shelf that he just asked you what you mean at all with this numbers - an idling pt6 has way more than 460 deg itt ;-)))
there are few pt6 installations where the readout is egt (t5) not itt with your numbers becoming realistic then , but in most installations including the -42a and itt readout recommending 425deg for cruise is plain funny
.
nervermind but you should cancel your comment about knowledge .
