Full Scale HSI

Radio Navigation Trainer

Free · Designed for iPad. Not verified for macOS.

Master the HSI. Fly radial intercepts, DME arcs and holding entries on a live instrument with a moving map — a procedural trainer built for instrument students. Full Scale is a radio-navigation procedural trainer that puts a glass-cockpit HSI and a moving map side by side — so you can finally see what the needles are telling you. Drag the aircraft anywhere. Drag the stations. Swing the heading with your finger. The CDI, bearing pointers, TO/FROM flag and DME respond instantly, and the map shows you the geometry the instrument is describing. Wind the clock up to 8x and watch a whole intercept unfold in seconds. BUILT FOR INSTRUMENT STUDENTS • PFD-style HSI with course pointer, CDI, two bearing pointers and DME readouts • Moving map with range rings, radials, course lines and your flown ground track • Wind that actually drifts you — see heading and track split, find the correction that holds the course • Holding patterns drawn at the size you would really fly them, with a live AIM entry-sector diagram • DME arcs with lead-radial guidance and wind-corrected headings • Marker beacons, NDB bearing work, station passage and the cone of confusion • Approach-chart PDF overlays: import a plate, the paper disappears, the ink lands on your map FREE TO TRAIN The trainer is free to explore: the complete HSI and map, dragging, wind, the entry diagram, and three full exercises — a radial intercept, a DME arc and a holding entry — with 15 minutes of flight time every day. Setting up geometry costs nothing; only the running clock is metered. FULL SCALE PRO — ONE PURCHASE, YOURS FOREVER • Every exercise in the library, plus all future additions • Publish your own holds — any fix, any course, left or right turns, timed or DME legs • Build your own DME arcs — any radius, any radials • Chart overlays and full nav-database editing, saved between sessions • Unlimited flight time — no daily meter No subscription. No account. No ads. No data collected. Works on iPhone and iPad, portrait and landscape, with full VoiceOver support. Full Scale is a training aid only. Its stations and geometry are placeholders on a training grid, not survey data. It is not for real-world navigation and is not a substitute for the aircraft flight manual or current publications.
