I had a strange moment in my last flight: when I selected a direct to the waypoint ATC told me to, the autopilot wanted to do a full circle:
I tried it a few more times and I got a new circle on my current position each time. When later I was told to go direect to another waypoint I had no issues, only RAVSA.
Also, is it true to life that autothrust does not turn off when you disengage autopilot? Previously it turned both off.
