User reviews

Very good

Just what I was looking to teach students HSI and Bearing Pointer basics. Spend a few minutes and the program makes sense once you see the lock colors change. I used to fly this EHSI in Learjets and Falcons years ago with an EADI, before the advent of the PFD. It’s still my favorite cockpit. Good app

Good but needs some work

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.

Very impressed

Hi, love the app. Would it be possible to have a few more speed options and angle of bank as well.

Really helpful for practicing IF

Great for your own practice or explaining to a friend how to do point to points and orientate yourself in IF. Speeding up the aircraft makes for a good challenge.
