I used to do it with elevator, till an instructor on one of the refresher
courses I took showed me how much better power worked for my airplane (a
cherokee six). I can keep the needle centered much better with small changes in
power than I can with the elevator. SO what I mean by controllability, is the
ability to keep the needle pegged.
