Fidelity, down to the last softkey

A G3X Touch™-style EFIS for X-Plane 12

The Emrelia E3X is a faithful re-creation of the modern general aviation touchscreen glass cockpit, or EFIS (electronic flight instrument system). A companion plugin connects it to X-Plane. We modeled it page by page against real avionics behavior, from data entry to autopilot mode logic.

FIDELITY

True to the real unit

We modeled every page, menu, softkey, and annunciator against the real unit's documented behavior. You get the same layout, the same controls, and the same features, so what you learn on the E3X carries over.

HARDWARE

Built for real cockpits

Use a touchscreen, a mouse, or a physical bezel (a hardware frame of knobs and keys). A ready-made map ships for the RealSimGear G500. RealSimGear G3X Touch bezel support is experimental and untested. It runs on Windows and Linux, beside your sim or on a dedicated panel PC.

INTEROP

Plays well with your panel

It mirrors your external IFR navigator's flight plan and procedures. It controls your COM and NAV radios, audio panel, and transponder. It couples to your aircraft's autopilot.

Primary Flight Display

An attitude you can trust — over terrain you can see

A full-tape PFD with flight director, an HSI (horizontal situation indicator) with bearing pointers, and minimums and altitude alerting. All of it sits over WebGL synthetic vision with terrain, pathways, and runway features.

Synthetic vision with terrain awareness and FLTA (forward-looking terrain avoidance) alerting
Round-gauge mode for classic panel layouts
Configurable data bar, wind vector, OAT, and timers

Moving Map & Charts

Sectionals, plates, and taxi diagrams

Pan, measure, and declutter across georeferenced VFR sectionals and IFR enroute charts. Georeferenced means each chart knows its real-world position, so ownship and route draw right on it. You also get current-cycle FAA approach plates, airport diagrams, and taxi diagrams. Fuel-range and glide rings answer the question you are actually asking.

Auto-zoom through departure, enroute, and approach
Weather: METARs, radar, winds aloft — real-world data

Engine Indication System

Engine pages that match your airframe

Data-driven gauges configured per aircraft, with lean assist, a fuel calculator, and CAS (crew alerting system) alerting. The E3X includes Skyhawk, Archer, SR22, RV-10, and twin Baron profiles, plus turboprop and jet layouts.

Zones, redlines, and alerts from the airframe config
Lean assist with per-cylinder EGT/CHT
Fuel totalizer and range planning

Panel Integration

One display in a bigger panel — the way it works in a real aircraft

The E3X does not pretend to be your whole avionics stack. It is built to sit beside your navigator, radios, and autopilot. It behaves exactly the way the real unit does when coupled to them.

IFR Navigators

Mirrors the full flight plan from an external GTN- or GNS-class navigator, including procedures, transitions, and missed approach. Works with RealityXP GTN and GNS, TDS GTNxi, and X-Plane's native FMS.

Radios & Audio

COM 1/2 and NAV 1/2 tuning, audio panel, and transponder. You enable each one individually, so the E3X controls exactly the radios your panel gives it.

Autopilot

Hybrid coupling: on capable autopilots, a G1000 or GFC 500-class AFCS (automatic flight control system), the E3X drives the autopilot's own native modes. On legacy autopilots it drives heading and vertical speed directly. That keeps VNAV (vertical navigation), GPSS (GPS steering), and glidepath working even when the panel's autopilot has no native modes.

Bezel Hardware

Plug in a RealSimGear bezel and its knobs and keys map to the same behavior as the on-screen controls. We include a map for the G500. The G3X Touch bezel is experimental and untested. Touch and mouse work without any hardware.

Coverage that's honest about where it's deepest

Worldwide terrain, weather, and airport data everywhere. The richest experience, with charts, plates, airways, and procedures, is in the contiguous United States today, and growing.
