I just flew the CRJ from Amsterdam to London Heathrow. I set my navigation by making Amsterdam my origin and Heathrow my destination. It plotted a route and had me reaching the top of my cruise at 38,000 feet. After takeoff I activated the auto pilot and it immediately put me into a steep climb that took me way above the green markers. The plane did eventually get near the 38,000 feet but it did not get to it. It was about 800 feet short when I passed where the plane should start descending. The plane wouldn’t descend. It stayed at about a 1400 fpm climb struggling to get to 38,000 feet while the green boxes descended quickly below me. I eventually had to turn the auto pilot off to get down to the right height. Am I doing something wrong? Also… Is there a way to set the maximum height of your cruise? For example could I have modified the 38,000 foot top and made it 28,000?
It just seems at a lot of time when you have navigation set and you turn on autopilot it does not stay with the green marker path.
I thought navigation was as simple as doing your origin and destination and adding any waypoints you want. Maybe I’m missing something and it’s more complicated than that. Thank you for any help that any of you can provide.
