If the seat sliding back were the problem, and he released the control wheel, the nose would pitch down some. I always left the trim neutral in pipeline 172s, which would even be more helpful here. Cary's slight down trim would be even better. The airplane could be, and perhaps was, controlled with the rudders only. We can and should maintain directional control, and keep the wings level, with rudder only. I left the trim neutral because I didn't climb and I always used full flaps on landing. Full flap trim is the same as cruise trim in most smaller Cessnas. My advise to all pilots, regardless of their particular power to weight situation, is to get off as soon as possible but to stay in low ground effect as long as possible. We never know when this considerable amount of free, extra kinetic energy might be necessary. Once in a high pitch attitude and out of low ground effect, low ground effect is difficult to regain.
