X-Plane 12 - MSFS 2024 - MSFS 2020
ICAONAV reads the aircraft from X-Plane 12 or Microsoft Flight Simulator and puts it on the official chart, on the iPad.
On the same PC, X-Plane 12.1.1 or newer is read through its built-in Web API (port 8086): nothing to install or configure in X-Plane. Older X-Plane, or X-Plane on another PC of the LAN, falls back to the classic UDP dataref link (port 49000), also without a plugin.
ICAONAV has its own SimConnect client that talks to the simulator over its named pipe or TCP. No SDK, no Developer mode, no SimConnect.dll needed; a simulator on another PC is reached by address. If you prefer the official SimConnect.dll, drop it next to the executable and switch the link in the settings.
Position, true and indicated altitude, height above ground, headings and track, ground speed and IAS, vertical speed, QNH (barometer setting), COM1 active and standby, squawk, Zulu time, on-ground.
The squawk and the COM1 frequencies you type on the iPad keypads set the transponder and the radio in the simulator (MSFS via SimConnect events, X-Plane via the Web API; the UDP link is read-only).
Follow and track-up, zoom presets (ENR, CTR, CIRC), the flown track, the airspace you are in and the one ahead with its frequency, reporting points with ETA, the VAC and AD INFO of the nearest aerodrome, 3D, cockpit and terrain views. Add the page to the Home Screen for a full-screen cockpit display.
PLAN opens the same sheet as the simulated flight: departure, destination, via points, arrival point, cruise level with the terrain check. The planned route is drawn in magenta, the track you actually fly in orange, so the two can be compared and the controller sees where you are going.
Anyone on the LAN opens the controller page: strips, radar view, warnings before you enter a CTR or TMA, clearances pushed to your page for the readback. The simulated aircraft of other pilots fly in the same airspace as traffic.
Inside: ICAONAV.exe (one self-contained file, no .NET to install), the data folder (aerodrome list, frequencies, reporting points, phraseology, airspace classes) and wwwroot (the pages).
Windows 10/11 64-bit; internet on the PC for the map tiles and airspaces (cached afterwards); X-Plane 12.1.1+ or MSFS 2024/2020 for the simulator seats. The eVFR Manual (aerodrome charts) is not included: download it in the app with your own Skybriefing account.
