So I was recording a video for youtube when I noticed that after engaging VNAV, I went into a 6k FPM climb. I decided to turn that off and switch to the Altitude and VSPEED knobs and autopilot would ignore that and STILL go into a 6k FPM climb. Even after I reached my cruising altitude of 37000, it still was doing 6K FPM 30dg climb.
The flight director was just fine and hand flying it was perfectly normal. I think its a problem with autpilot.
Video coming soon
