I decided to use the 787-900 for the first time today in IF, and the experience was horrid to say the least. Why was it bad? Because of the Auto Pilot.
First off, when I started my flight and got airborne, the autopilot could not keep the heading straight. It constantly kept doing left and right turns to try to get the correct heading but it couldn’t get it to hold steady.
When I started my decent to the airport, it got worse. It was overshooting the heading I set for the autopilot by 10 degrees and kept doing sharp left and right turns, attempting to re-align with the heading.
In addition to this, I set the autopilot to decend from 10,100 feet to 2,000 feet at -1,500 FPM. Out of nowhere, the planes autopilot put the aircraft in a steep -3,500 FPM dive (keep in mind, I double checked the FPM and it still said -1,500 and the autopilot did not disengage). Then, at around 4,000 feet, it began to climb steeply at 3,600 FPM (even though it should have still been descending to 2,000 feet). At this point, my approach was completely messed up and I was upset so I just ended the session, haha.
Does anyone else have a problem with the 787-900? The aircraft was pretty much un-flyable unless you flew it manually for the entire flight, and on a small iPhone 6s screen with minimal practice flying planes manually, it was impossible for me.
A small detail that I forgot to mention was that it couldn’t get the speed correct, this wasn’t a huge deal and was the least of my problems; however the autopilot kept the plane around 7 knots under the set speed.
