Radial intercepts, TO/FROM, ADF and RMI bearings, holding entries — on real instruments over real navaids. And cockpit view of real map. Radio navigation clicks when you fly it, not when you read about it. VOR Sim is a procedure trainer for iPhone and iPad. A light flight model sits behind a full six-pack panel, a moving map, a synthetic outside view and a GNS 430-style GPS, so the needles stay the thing you have to concentrate on. Nothing to configure, no aircraft to buy, no scenery to download: press START and intercept something. THE PANEL • Classic VOR head (NAV1) with a rotatable OBS ring, CDI and TO/FROM flag • HSI (NAV2) with course needle, deviation bar, heading bug and an ADF pointer • Twin-needle ADF: tune two NDBs and cross their bearings for a position fix • The ADF card is fixed, slaved to the compass (RMI) or set by hand — the three ways a real ADF head is read, one knob apart • Directional gyro that precesses about 10° in 15 minutes, and has to be reset • Airspeed with an RPM sub-dial, attitude, altimeter with hPa subscale, VSI and turn coordinator • Spread two fingers on the panel and the three nav heads take the whole screen, which on a phone is the only way to read half a dot; the V1 · V2 · ADF buttons under the panel decide which of them are up and how the width is shared — V2 steps HSI → second VOR head → off, ADF two needles → one → off • Every card and ring turns under the finger: the OBS ring on the VOR head and the HSI, and the ADF card, which takes itself off the compass when you do REAL NAVAIDS • About 17 000 airports and 10 000 VOR and NDB stations from OurAirports, all bundled, all offline. Positions, idents, frequencies and runway directions are real • Long press a VOR on the map to tune it on NAV1, then NAV2; long press an NDB and it goes to the first ADF needle, then the second • Long press an airport to fly direct to it MOVING MAP • Your aircraft, its breadcrumb track and every station, draggable — build an intercept in seconds and drag the aeroplane back to fly it again • The selected OBS course drawn through each VOR with TO/FROM arrows and radial numbers pinned to the screen edge • A chart scale bar you can long press and slide to zoom • Or take the ground away: a second press of MAP leaves the stations, radials, track and airspace on black, which is how a radial is easiest to read GNS 430 • Direct-To, a flight plan with automatic leg sequencing, OBS suspend, CDI source switching between GPS and VLOC, COM and NAV tuning • Any bundled ident can be typed in, with a match list from the database FLYING IT • Tilt the device like a yoke — tilt is elevator, rotate is ailerons — or use the on-screen stick, rudder and throttle. Hardware keyboards work too • Controls are damped the way an aeroplane is: an input arrives over about a second, and the turn builds up after it • Engine sound synthesised from the rpm, from a lumpy idle to full power • Wind with gusts, 1–4× time compression, a stopwatch for timing a hold • Power off, the nose has to come down; below about 45 kt the wing stalls, with aileron on it spins, and the ground ends the flight • A turn costs what it costs: 1.4 g at 45° of bank, and either the nose falls or the speed does OUT OF THE WINDOW • Look out over the cowling — the nose is the attitude reference in a real aeroplane, and where the horizon sits above it is your pitch • Or switch to the glass panel: the nose goes, and the horizon, a pitch ladder, a bank scale and boxed speed, height and climb are painted on the window, so the view can be flown on its own • The ground under you is the real countryside, from the map The training area centres on your position, or on EDAZ Schönhagen. Switch on "Reset moves you somewhere new" and every reset deals the exercise at a real aerodrome somewhere else in the world, with the real VORs around it. Made by a pilot, for pilots and for students working on the instrument rating. IMPORTANT — the airspace, and the exercise stations dealt by a reset, are invented for training. Nothing in this app may be used for real navigation. ## Rankings - #2,311,791 — Overall ## Similar extensions and apps - [VOR ADF Simulator](https://chrome-stats.com/d/id6756212116) - [VOR Tracker - IFR Nav Trainer](https://chrome-stats.com/d/id813825630) — 4.70 / 5 - [VOR Simulator Pro](https://chrome-stats.com/d/id6743936925) — 4.60 / 5 - [Flight IFR Nav Trainer](https://chrome-stats.com/d/id1161716505) — 4.60 / 5 - [Nav Trainer Pro](https://chrome-stats.com/d/id427480051) — 3.90 / 5 - [IFR Flight Trainer Simulator](https://chrome-stats.com/d/id901798935) — 3.90 / 5 - [IFR Simulator](https://chrome-stats.com/d/id6757545608) - [flyNav Flight Navigation](https://chrome-stats.com/d/id1043488673) — 1.50 / 5 - [IFR Trainer](https://chrome-stats.com/d/id1551480486) - [VFRnav Flight Navigation](https://chrome-stats.com/d/id1553754024) — 3.90 / 5 - [VOR + ILS Trainer – IFR Pilot](https://chrome-stats.com/d/id674943712) — 3.30 / 5 - [Navigator: Instrument Training](https://chrome-stats.com/d/id358957074) — 5.00 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/id6795129488)
