WASD to maneuver plane F for flaps. G for gear. L for lights. 1, 2, 3 for difficulty. Space bar to change instrument panel. C to access flight computer. V to check flight computer values. B to disable flight computer. Use flight computer at your own risk. Still very buggy. Finally, it's done.
Don't mess around with the FMC. Seriously. It will do some wild stuff. Someone fix bugs please. All me. Everything. Please heart and star I've spent so much time on this The FMC doesn't have to work. 172 doesn't have on IRL...
