Coming up to an instrument flying exam, or maybe you just want to brush up on your point to point navigation?
Well, this is the app for you.
HSI is a VOR/TACAN/LOC/NDB navigational training tool that you can take in your pocket.
Initially developed for Australian advanced flying training, HSI will help you get your head around concepts like arcing and point to point navigation by providing an inexpensive, hassle free way to practice them to your heart's content, wherever you may be.
Does not have any glitches or anything so thats good, but you need to have a simpler user interface or make a tutorial, i had to figure out how to work with the app, would be nice if you explained how to work it before hand.
