I'm looking for some form of virtual Co-Pilot that will answer radio calls and make instructed course corrections whilst using auto pilot.

It's very frustrating that if I plot a flight that is 4 hours long I have to stay in my chair for the entire 4 hours in case I miss a radio call and get my flight plan canceled.

FSX claims to be "as real as it gets" but a real pilot would not have to stay in their chair they could get up and walk around or even have a sleep and their co-pilot would handle the plane.

And before everyone starts mentioning It's your plane I already looked at it and cannot find a clear indication that it does what I want and the demo that is supposed to show you what it can do is useless since it only lets you use limited features in a Cessna which I have no interest in and is nothing like flying jets.

I also do not need something to do as much as that so would be paying for loads of features I would never use.

I also have a major problem paying more for an add-on than the original software it is being added to cost.

So are there any other options?
