Autopilot Mode
I had to fly a King Air 200 yesterday. It was equiped with a Collins APC-65 Autopilot. It has a Mode Button called SPD-PRF. The 200 I normaly fly doesnīt have this Button and the Manual also didnīt say something about it.
All I could find out is that you can use IAS Hold or SPD PRF. I tryed it on the Ground, when you are in IAS Hold and you press SPD PRF, IAS Hold comes off and vice versa. I didnīt wanted to try it airborne. Maybe one of you Guys can help me.
