Centaurus:
Further to my last post, I have just read the latest version of the FCTM which also recommends using trim if in a wings level nose high upset ( greater than 25 degrees nose up).
It states
In this situation the pilot should trade altitude for airspeed, and maneuver the airplane's flight path back toward the horizon. This is accomplished by the input of up to full nose-down elevator and the use of some nose-down stabilizer trim.
What version number of the FCTM are you preaching from?
