What's a good iOS game for getting into the nitty-gritty of flying without needing, like, a whole PC setup?

Okay, so Infinite Flight Simulator is pretty cool if you're into aviation but don't want to drop a ton of cash on a full-blown PC sim. From a technical standpoint, the flight model is surprisingly detailed. I mean, you can actually feel the difference between a Cessna and a 747, which is saying something on a mobile device. The physics engine seems pretty legit too; I haven't found any major glitches or weirdness there. They've got a decent selection of aircraft, though some are locked behind a subscription (typical these days, right?). It loads up pretty quick, too – about 3 seconds on my iPhone. I've seen other sims that are just total resource hogs, but Infinite Flight Simulator seems optimized. I mean, it barely uses 60MB of RAM when I'm just cruising around. If you're into planes and want something more than just an arcade-style flyer, this is worth checking out. No more spaghetti code situations here, I hope!
