Would someone please explain to me how the Altitude Selector works in the 609B?  Not being able to find any definitive directions issued by Carenado, I thought it might be a United Instruments 5506L Altitude Selector and would function like the altitude selector which is coupled to the Collins AP-106 in the Twin Otter.:

1. Dial in a altitude using the knob provided on the selector

2. Turn on the Collins AP-106 leaving it in "manual mode" and establish a ascend/descend pitch using the controls located on the center console

3. Push the "Alt Alert" button beside the altitude selector

The altitude selector will alert you twice prior to reaching the selected altitude and will level the aircraft upon reaching that altitude whereupon the "Alt" button will light on the autopilot

I an not able to accomplish the above in the 609B and so I must be incorrect. Any help and/or suggestions would be greatly appreciated!

The alert is to give you a heads up for when you need to hit the Alt Hold, it won't capture it! Not sure if that is how the real AP works in the AC690 but that is the way Carenado modeled it?

Thanks, Martin. I appreciate the information. John
