## Description

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. Not affiliated with any aircraft manufacturer or air force.
