there r 2 flight type, simulation and game
in simulation then this is essentially the Falcon 4.0 of A-10 (though the campaign is not dynamic like Falcon 4.0 unfortunately) ie: if u do not want to learn the avionics and handling of the A-10 then u can forget about it because it's as close as it gets to the real thing that is available in the commercial market. You will handle EVERYTHING that is not classified and relevant (some parts are omitted) ranging from power management, damage control, countermeasures, target acquisition, and pretty much everything else the real pilot will handle though some of them can be assisted.
in game mode things are simplified to about 1/10 th, so you can do things like simply cycling through targets who are conveniently labelled and highlighted with large brackets and then just fire your fire and forget maverick.
in essence game mode is a bit closer to Ace Combat in that sense or the older arcade flight game.
But the game obviously lose a great deal of it's appeal when played in game mode.
The good news is, if ur used to the flight sim title like Falcon 4.0 or Jane's old flight sims then most of the avionics are easy to adapt to, they look different, sometimes positioned differently as well but most of the functions are similar except that you never had to deal with radar in A-10 (which is a blessing or a curse depending on how u look at it).
