HSI - Instrument Approach Sim

iOS Universel / Education

HSI - Instrument Approach Trainer is the only app that lets you import real PDF approach plates and fly approaches right on top of them. Whether you're a student pilot preparing for your instrument rating, a CFI teaching procedures, or a current pilot staying sharp — HSI puts realistic approach training in your pocket. Initially developed for Australian advanced flying training by an Air Force Qualified Flying Instructor - HSI is built by a pilot for pilots.

WHAT MAKES HSI DIFFERENT

Import Your Own Approach Plates Load any PDF approach plate and practice the procedure as published. No other app offers this. Fly the approaches you'll actually fly in the real aircraft.

Realistic HSI Instrument - A beautifully rendered HSI with course selector, CDI, and heading bug. Designed after modern glass and PC-21 style displays.

Multiple Nav Modes - Practice VOR, TACAN, LOC, and NDB approaches. Set up any scenario with customizable navaid positions and approach tracks.

Holding Patterns - Practice standard and non-standard holding patterns with automatic entry selection. Direct, teardrop, and parallel entries with live guidance overlay. DME and timed holds included and fully customizable.

Wind - Set wind direction and speed to practice real-world conditions. Essential for instrument rating prep.

Global Leaderboard - Compete with pilots worldwide in Fix-to-Fix challenges. See how you rank.

Built-In Fix to Fix (Point to Point) Training - HSI and map overlays that help you visualise this skill.

Speed Control - Run approaches at 1x, 2x, 5x and 10x speed. Slow it down to learn, speed it up to drill.

WHAT PILOTS ARE SAYING — 4.5 stars from pilots who use it

"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. HSI Pro costs a fraction of that — once. Practice unlimited approaches and walk into your next checkride, sim session, or flight with confidence.

PRIVACY HSI collects zero personal data. No accounts, no tracking. Just training.
