I'd like to say that if you make some sort of "auto corrector" component for ships that makes them fly more like people are used to ships in video games flying, make it not very hard to get, but make it really kill the speed of the ship. Beginners will probably appreciate being able to get around easily, but everyone will move to the more realistic mode because of the huge in-game advantage. Or they'll get someone else to do thier flying for them.
To directly answer the question at hand: To fly a ship, a user should require almost no skill. To fly a ship with any real power, aside from slow people-moving, a fair amount of skill should be required. To really be a fighter ace, you should actually have to be a damn good pilot. Yes, this makes people that are good at flying fundamentally better than others. That's how life works, though. You'd better pick up some sort of skill!
Although, maybe that's just the fact that I always get annoyed at how unrealistic the physics engines in all space-fighter-type games I've played. <:o)
