Constant Speed Prop Question
Hi There,
I've done a search for this, and can't find any reference to it, so I'll post the question here!
Can anyone explain why some constant speed prop installations have a small 'red' zone indicated somewhere in the middle of the green zone? For example - RPMs are in the Green from x to 2000 rpm, Red between 2000 and 2300, then Green again from 2300 up to the actual red line. What's going on here??
Many thanks,
David
