Keeping up with aviation apps for the iPhone is nearly a full-time job, but staying current on these apps can definitely be worth it, according to John Ewing, a Gold Seal flight instructor who writes a blog at Aviation Mentor.
A good example, he says, is the suite of reasonably-priced apps from CFI Tools. He continues:
“This suite consists of seven apps and each has the stated goal of doing one task and doing it well, rather than trying to be the aviation/iPhone equivalent of a Swiss Army Knife. The advantage of this approach is that you only need purchase the apps that you want or need.”
He then takes an in-depth look at each app: The Crosswind Calculator, Holds Pattern Calculator, VOR Viewer, Weight & Balance, Mvx Tracks, Takeoff & Landing Distance, and Area Wx. Check it out here.
