Guppy , I believe this model of T182 has a 3 bladed McCauley , not a Hartzell Compact , boofhead ?? If so , this model of propeller has no dome pressure like a Hartzell . Governor oil pressure is used to increase blade pitch angle (low rpm) and the natural centifugal twisting moment of the blades (with a little help from a spring , I think) is used to decrease blade pitch angle (high rpm) . As Guppy has so rightly said , at any time the prop control is fully fwd (in) , the blades should be on their fine pitch stops and red line rpm , 2400 in this case , should be achievable on advancing the throttle . Listen to him , he knows his stuff !
