Why is it that I find myself confronted repeatedly with Caravan pilots that seem to have NO concept of how to use the Pratt & Whitney PT6A-114A or any Turbine for that matter? What's even more entertaining is the fact that most of these 'pilots in question' will still stick to their story under repeated scrutiny.
I think we need to cut straight to the point .... No, you do not use % of NG to set your power!
If your NG is any where near 101.6% in cruise, you should be worried.
If ITT is anywhere near 740 or more in cruise, well thats not good. Besides the fact that they are both just plain old WRONG!!
Your power is set by Outside Air Temperature, Altitude and aircraft weight ... it's in your POH! Maybe we need to start calling it - Idiots Guide to Flying the Cessna Caravan or Flying the Cessna Caravan for Dummies.
Remember that ALL OTHER engine parameters are only monitored to verify they are within acceptable limits !
