I just bought the gulfstream g650. I have been using the Cessna 172 and its going well. I downloaded plane and read help me and some other things but I don't understand when to use the flight management system vs Auto pilot. Also I can't find a tuitorial on trying to program a flight management system route or using the ILS systmen. The 172 I never used the autopilot and not sure it even had one.

 

Any help is great thank you

I'm late to the game but here are some answers for you.

 

You can use the auto pilot by itself...while not using the FMS/FMC but for a typical flight you would use both together.

 

The 172 doesn't have an auto pilot.

 

As for programming the FMS, didn't the 650 come with any manuals? You'll need the manuals or the tutorials to learn how to program in a route into the FMS.
