??

I fly a 767 and bought this for FMS review. I dont use it on a flight sim game because I just want to practice route change scenarios.
Looks good, but after the flight plan is entered, the modification inputs act nothing like the real FMS. Also, I cannot get the airplane "in the air" and there are no instructions or any type user manual that I can find.
