Today we recommend glass panels or Electronic Flight Information Systems (EFIS) which includes the flight and engine monitoring systems

New MGL Discovery Touch Screen Panels

The newest optimum EFIS which is also a GPS system is the MGL Discovery panel.


The iEFIS Lite series from MGL Avionics is set to revolutionize the small airplane instrument panel. If just a single EFIS screen is required in your Experimental or Special LSA, the iEFIS Lite offers everything needed.

The first release is the Discovery-Lite 7”, which has a nice, bright non-reflective 7″ touchscreen of around 1000+ nits. It looks, feels and operates just like a full iEFIS.

We gain a built in GPS, attitude sensor, airspDiscovery_Smalleed pressure sensor as well as altimeter. It also has a built in OAT sensor (but an external one can be fitted). It has a CAN bus as well as two RS232 ports, for external devices such as radios and transponders/ADS-B transceivers.

The single CAN bus supports any number of MGL Avionics devices, such as engine monitoring modules (RDACs), transponders, SP-6 Compass sensor. You can also connect up to three external SP-7 attitude sensors if required.

DiscoveryLiteRear”Lite’s” are straight forward to install and make great panels for many smaller aircraft that would like a sophisticated EFIS but without the cost and complications of a large system.

A typical Lite system would be: The Discovery-Lite panel, an RDAC for engine monitoring (if needed), and perhaps an SP-6 compass. That is it!

The panel may be mounted at any pitch angle relative to the aircraft despite the built-in AHRS. The AHRS can be easily rotated to provide the expected image.

You can completely customize the screens like you can do with our other iEFIS systems and you can also select from many built-in choices for a quick “plug and play” installation.
Like all our G3 iEFIS systems it comes with a World wide high resolution terrain database built in plus a World wide vector map. It is compatible with MGL’s new “MapMaker 2” raster map format.

Notably, the G3 iEFIS systems boots to operational state in 0.5 seconds (zero point five) from application of power. GPS is online 0.5 seconds later (provided you have not moved more than 500 Km from last known fix and a fix is possible). Synthetic vision, terrain data, maps etc are all up and live in a blink of an eye.

The Discovery could be viewed as a direct replacement for our popular Enigma that was discontinued a while ago. It is similar in panel size but with a bigger, much higher resolution screen and of course is a powerhouse of functionality where needed…

The iEFIS Lite is available in 3 screen sizes:

Discovery-Lite: 7” diagonal screen size (800 x 480 pixels – WGA)
Explorer-Lite: 8.5” diagonal screen size (800 x 480 pixels – WGA)
Challenger-Lite: 10.4” diagonal screen size (1024 x 768 pixels – XGA)

XTreme mini EFIS

This typically comes with the higher end trikes and can be effectavly used in combination with an iPad or iPad Mini. It has many of the features as the iEFIS above but no moving maps (which you can get with the iPads.
Xtreme All

Smaller color EFIS is the XTreme EFIS is an affordable mini EFIS. It can be configured as a PFD (with AHRS sensors added), and/or an engine monitor (with RDAC added). It includes a GPS receiver that is used to provide ground speed and range information, as well as a backup/control for the AHRS. If you do not select the SP-4 attitude sensor, you can still have a GPS-derived bank angle display!

Stratomaster MGL Enigma

The classic EFIS which is also a GPS  system is the MGL Enigma. This is a top of the line affordable comprehensive system that optimizes your instrument panel with one simple instrument. This has been discontinued but is is still supported by the MGL factory and provided here since it is on many trikes out there and a great EFIS.
