I've read all the 'destructions' with regard to auto pilot and I still don't know where I'm going wrong.
e.g Dept Ncle on Runway 25. Auto Pilot set at Heading 197, speed 330, hight 5,000. When I engage auto pilot the aircraft turns to the set heading, the speed seems about right but it will not lock onto the altitude setting. It feels like it just wants to nose dive.
Any pointers chaps?
