It's either I'm doing something wrong or somebody could explain a way out of my situation. As soon as I disconnect the autopilot, the airplane is immediately pitching up. How can I avoid it? For example, as soon as I'm ready for a touch down, I turn the autopilot off to land the airplane and it's pitching up rapidly causing a crash. Why is that? Any ideas would be appreciated.
A mile of runway takes you to the world. A mile of highway takes you a mile.

the autopilot uses trim for pitch control. in various high alpha situations for example when slow with flaps out and gear down, you will have a massive pitch trim by the auto pilot, usually visible on the panel and, on modern models, from the outside. try correcting the trim in pause. it will not occur then
