Emrelia E3X
A 10.6-inch-class touchscreen EFIS (electronic flight instrument system) experience for X-Plane 12. Fly it by touch, mouse, or real bezel hardware, with the page flows, menus, and mode logic of the real thing.
How the X-Plane plugin works →
Fly the tapes, see the terrain
Airspeed and altitude tapes, attitude with flight director, VSI and vertical deviation, HSI (horizontal situation indicator) with dual bearing pointers, baro minimums, and altitude alerting. All of it draws over WebGL synthetic vision with terrain shading, pathways, and runway features. A round-gauge mode covers classic panels.
The map answers questions
Fuel-range and glide rings, airways and airspace with smart declutter, obstacles, and traffic. Topo, sectional, and IFR basemaps, night mode, profile view, and auto-zoom that follows your phase of flight. Pan and measure with a finger.
Plan, fly, descend on profile
Full flight plan editing with saved plans, Direct-To, approach loading, user waypoints, and VNAV (vertical navigation) guidance. When an external navigator owns the route, the E3X mirrors it, the way the real unit does.
Weather, terrain, and traffic — from real-world data
Live METARs, TAFs, SIGMETs and PIREPs, precipitation radar, and winds aloft. Terrain alerting with FLTA (forward-looking terrain avoidance), traffic display with alerting, and airspace proximity alerts. Weather comes from real-world sources, so the picture matches the world outside your sim.
Georeferenced charts, current-cycle plates
Georeferenced VFR sectionals and IFR enroute charts know their real-world position, so your ownship, route, and traffic draw directly on the chart. Approach plates, airport diagrams, and Chart Supplement pages come from the current FAA cycle. Find them by airport, one tap from the waypoint page.
An EIS tuned to your airframe
Per-aircraft gauge configurations with zones, redlines, and CAS (crew alerting system) alerting. Skyhawk, Archer, SR22, RV-10, and twin Baron profiles come included, plus turboprop and jet layouts. Lean assist watches every cylinder. The fuel calculator keeps totals and range honest.
Autopilot modes that behave like the book says
The full lateral and vertical AFCS (automatic flight control system) mode set: HDG, NAV, APR, ALT, VS, IAS, VNAV, GPSS, GA, LVL. It has proper arm and capture behavior, mode annunciations, and flight director cues. On aircraft with a capable autopilot, a G1000 or GFC 500-class AFCS, the E3X drives the autopilot's own native modes directly. On legacy autopilots it falls back to driving heading and vertical speed itself. You keep VNAV, GPSS (GPS steering), and glidepath guidance on autopilots without native mode support.
Twenty setup pages deep
Display, sound, units, alarms, traffic, weather, position, keyboard, navigation, track log, flight log, engine, aircraft config. The setup pages are all there, along with checklists, nearest, and waypoint information pages.
Built to sit in a panel, not own it
In a real aircraft the G3X-class display is one node in a stack of avionics. The E3X reproduces that. It defers to your IFR navigator, drives your radios, and couples to your autopilot, and you can configure each integration individually.
External IFR navigators
Couple the E3X to a GTN- or GNS-class navigator and it mirrors the navigator's complete flight plan. That includes initial approach fixes, transitions, stepdowns, and the missed approach, exactly as the real unit does. The pilot loads procedures on the navigator, and the E3X displays and follows the route it did not compute. Works with RealityXP GTN and GNS, TDS GTNxi, and X-Plane's native FMS.
Radios, audio panel, transponder
Six items enable independently: COM 1/2, NAV 1/2, audio panel, and transponder. The E3X controls exactly what your panel hands it. Disable a radio and its CNS cell, menu tile, frequency-load targets, and CDI sources all follow, just like configuring the real unit.
Autopilot coupling
Hybrid native-autopilot control drives your simulated aircraft's own ALT/VS/FLC/HDG modes when its autopilot supports them. A G1000 or GFC 500-class autopilot couples natively. On legacy autopilots the E3X falls back to steering heading and vertical speed precisely through the flight director. That means modes only the E3X computes (VNAV, GPSS, glidepath, go-around, and level mode) work in any X-Plane aircraft with an autopilot.
In the 3D cockpit
On X-Plane 12.1 or later, an optional install component renders the E3X directly onto the panel of a generated, E3X-equipped Cessna 172. Or fly it in pop-out windows beside the sim, on any monitor or touchscreen. Run one display, or a PFD and an MFD side by side. If one goes dark, the other reverts to a combined flight instrument, engine, and radio layout, just like the real installation.
Data coverage by region
Terrain, weather, and airports are worldwide. Charts, airspace, and procedures are richest in the contiguous United States today. Here is the honest breakdown.
