[quote=Mr.Buzzy]I remember it being common practice to wind full "nose down" then winding on 4 and half turns of "nose up" before takeoff in the PA31. People have been distracted in the past after performing the first half of this procedure and attempting takeoff.
I used to use 3 1/2 turns nose up in VH-NPD. The reason I started doing this was because the trim indicator would read inaccurately due to static electricity on the plastic cover over the trim indicator, wiping or cleaning this cover would couse large changes in the indicated trim setting.
