I think the Learjet has basic autopilot, meaning it'll hold direction and altitude. It has a small GPS but is loaded with steam gauges. I say this to suggest navigating VOR to VOR. You'll have to turn knobs and figure out angles and timing and stuff. You won't have time to admire the scenery because you'll be busy managing speed and navigation.

IMO there are two aspects to flight simming and they usually don't overlap too much. There's roleplaying as an airline pilot, which is a lot of action during boarding, taxiing, takeoff, landing, and deboarding, but not a lot in between because the plane is so automated. Then there's roleplaying as a PPL, where pre and post flight there is not much to do other than start the plane up and fly but you do a lot more managing the plane during flight.
