Reward: Top 5 Highest Airports
Difficulty: Easy
Estimated Time: Varies
As you can see in the image, you have to land at SPRF, VI66, SPVI, SLCN, and SLLP to receive this award. These are the five highest airports in Flight Simulator X. Most have elevations around 13,000 ft, so make sure that the aircraft you choose is able to climb above that altitude. If you can't get any power out of your engine, don't forget to lean the gas mixture (pull the engine mixture control towards you until your EGT gauge peaks, then push it in just a touch) or enable the engine auto-mixture (in the aircraft realism settings panel).
The easiest way to land is by taking off with a helicopter, hovering 100 feet above the runway, then setting it back down.
