Although power and attitude changes are almost simultaneous, we will lead with PCL
movement, then set the new attitude as we continue the PCL to desired power range. After the
power and attitude are set, trim.
From aerodynamics courses, we have learned that if we have our aircraft trimmed for balanced flight
and change power or airspeed, we need a trim change. In this section, we will review the type of
trim needed and how to trim, vice the aerodynamic reason for trim.
