Hi folks, I can't get the AP to capture the target altitude. I'm using the PMS 650 and the Logitech AP panel, which both work, except for the altitude. It doesn't matter which mode I use. 'Alt Sel' is active, but the autopilot doesn't level off at the selected altitude, regardless of whether 'Auto Arm' or 'Manual Arm' is selected. I also disconnected the panel, but that didn't help.
Otherwise, I have no problems. The AP follows GPS and heading (I haven't tried ILS and RNAV yet).
