Well grab your dumbells, because we're here to help "pump you up"!

Actually, adding a Wii nunchuk to the PC would be appropriate for approaching the physical requirements needed to manage a WWI fighter.

Imagine changing the pan magazine on an Se5a in a dogfight? Stick in one hand, with the other unlatch the MG lock on the Foster mount and securely ease back the weapon with the lanyard, unlock the magazine and stow it inside the cockpit, grab a loaded drum and place it on the Lewis Gun, ensure it's locked in place, charge the weapon, and then pull the MG back up the rail till it latches again, all against a 100+ mph headwind, while maintaining control of ones aircraft, and avoiding the enemy (if possible). Try creating the animation for that, let alone the interactive control requirements in-game. Then make simmers do it every 97 rounds they fire off:



Note flare gun for signalling in the flight leader's hand in the photo above (gotta grab the nunchuck again).

Simple cockpit management requirements? Again the SE5a and its fuel management system:



Note the air pressure hand pump (nunchuck again).

We could go into greater detail on the methods of identifying the type of MG stoppages that occurred in combat for instance, and the procedures for physically clearing jammed guns in the air, or the proper positioning of radiator shutters to ensure correct engine running temps, or perhaps the requirements for adjusting the fuel lever setting vs. the throttle position to prevent lean or rich cut-out (and the need to do so every 1000 feet or so of altitude changed).

Those that think flying WWI aircraft was somehow easy are harboring grand illusions (mainly because they have no idea what was involved). Certainly these early military aircraft didn't have the array of switches, gauges, and buttons needed to monitor their flight systems, and that's just the point. They flew with brute strength, and managed much of their aircraft's systems by hand, in freezing temperatures, exposed to the elements, and without oxygen assist, and alone without a radio or guidance system to help them back home.

Actually, I don't even think our PCs now can ever do the WWI combat pilot's experience justice, and maybe giving us soft-butted simmers a little physical work to do in our combat games would be a good idea (a PC and nunchuck huh, I like it)!
