The IFD-NET Evo EFIS Plus is the flagship all-in-one digital flight instrument in the 80mm Evo range. While the "Base" model provides a high-quality artificial horizon, the Plus version unlocks the full suite of navigation and situational awareness features, making it one of the most capable "glass cockpit" instruments for the UK's microlight and experimental aircraft market.
Unlike the "Slave" units we discussed, the Evo EFIS Plus is a standalone Master unit. It contains its own internal sensors and does not require another device to function.
What makes it the "Plus" version?
The hardware (screen and bezel) is the same across the Evo line, but the Plus software adds several critical "big-jet" features to the small 80mm form factor:
Synthetic Vision (3D): Instead of a simple blue/brown horizon, it renders a 3D digital representation of the terrain ahead. This is a significant safety boost when flying in hilly areas of the UK (like the Highlands or Wales) or in low visibility.
Moving Map: A dedicated navigation page with a geographical database. It shows your position, track, and nearby waypoints.
TAWS (Terrain Awareness): It provides visual alerts if your flight path conflicts with rising ground or obstacles.
Multi-Screen Selection: You can toggle between up to six different screens, including a dedicated HSI (Horizontal Situation Indicator), a "Nearest" airport/waypoint list, and a G-meter page.
Integrated GPS: It comes with an internal high-sensitivity GPS receiver (and typically an external SMA antenna connection) to provide ground speed and track data.
Pilot Use Case
For many UK pilots flying aircraft like Eurofoxes, Ikarus C42s, or RVs, the Evo EFIS Plus is used as the primary flight display.
Panel Upgrade: It is designed to "drop in" to the hole left by an old 3.125" mechanical altimeter or horizon, requiring no panel cutting.
Redundancy: Because it has a built-in "Fly Bus," you can connect an Evo Slave EFIS to it. The Plus unit does all the "thinking" (sensing the movement and GPS position) and simply tells the Slave unit what to display.
Power: It runs on standard 10–30V DC, drawing very little current (approx. 200-250mA), which is helpful for aircraft with limited electrical systems.
Comparison: Evo Base vs. Evo Plus
Evo Base: Gives you the AHRS (Horizon), Speed, and Altitude. It is a "replacement for the steam gauges" only.
Evo Plus: Adds the 3D Synthetic Vision, Moving Map, and Navigation database. If you want to use the instrument for navigating and cross-country flying, the Plus is the necessary choice.
