WHAT PILOTS ARE SAYING — 4.5 stars from pilots who use it "This app is probably the only reason HSI needles made any sense to me. It’s like a sandbox for learning instruments. Highly recommend!" "I still use it to keep my skills up after a break from IF flight/pre IRA" "Great tool to brush up on IFR point to point concept and hold entries" "If you don't fly much IF this HSI tool will help you out" "Great for your own practice or explaining to a friend how to do point to points and orientate yourself in IF" SAVE MONEY A single flight hour costs hundreds of dollars.
