For Each Installation an RDAC Engine Monitor is Required
The most flexible EFIS!
The Enigma is a comprehensive flight, engine and navigation instrument designed for Experimental and Light Sport aircraft. The Enigma is a hardware and software concept that promotes a flexible, powerful EFIS platform together with a software application system that is highly user-modifiable.
As an EFIS hardware platform, the Enigma provides state of the art multi-processor based processing utilizing components chosen for absolute robustness in radiation intense environments such as found at high altitudes. This is coupled with intense low power design methods to further maximize overall system application and reliability.
The large amount of flexibility built into the base system allows the adaptation of the Enigma to almost any mission and aircraft. Due to low system cost, Enigma is equally suited to very light aircraft, gliders and rotorcraft, while providing enough flexibility to be utilized by even twin-engine aircraft with full dual engine monitoring.

The Enigma, Voyager and Odyssey each feature 9 fully user-programmable screens. You can choose from our standard screens (the unit ships with 9 pre-designed screens) or you can use our PC-based editing software to design unique screens. Hundreds of highly configurable instruments and display items in various forms are available to choose from. From traditional analog gauge displays to bargraphs, digital readouts, horizons, HSIs, moving maps, etc. The choice is yours! And if you don’t want to get too involved, just keep the standard screens, or contact us to design a special screen for you, free of charge.
To select one of your 9 screens, simply press one of the buttons numbered 1 to 9 on the keypad, and your next screen is up!
The Enigma/Voyager/Odyssey can interface with the Garmin SL30 Nav/Comm and display active and standby navigation on the screen with an HSI with Glideslope indicator. In this case the OBS knob on the SL30 is used to set OBS.
Alternatively, your MGL Avionics EFIS can ‘fake’ radio navigation using only its onboard GPS and database of VOR stations and ILS approaches. We call this GPS VOR (GVOR) and GPS ILS (GLS) navigation.
The Enigma/Voyager/Odyssey features a 16-channel WAAS-capable GPS receiver, with a host of moving map navigation features. All GPS databases are from freely available sources, and are editable by the user where applicable.
The following map layers are available for display on the Enigma:
- 1. Airports/Waypoints database
From the free database in GPX format at www.navaid.com. Includes runway information and frequency information. Entire world.
- 2. Airspace
Entire world. User-editable..
- 3. Terrain
In GTOPO format - freely available.
- 4. World Vector Basemap
Major roads, rivers, borders, cities and towns for the entire world.
- 5. Raster
Any scanned image (or digital Sectional file) can be used after processing with our Map Maker software.
All of these layers (except raster) are shipped with each EFIS. Most data is stored on the SD card, except Airport information, which is stored on internal memory.
- Goto Function activates basic Gotos from list of Nearest Airports as well as from searches for airport identifier or name.
- Route function allows you to activate routes from SD card (created in our Flight Planner software) or routes created directly on the EFIS.
- Airport Information. Click ZERO at any time to bring up nearest airports detailed information including runways, frequencies, etc.
- Airspace awareness (Information Management System (IMS)). Click SHIFT and then 6 (IMS) to bring up details of airspace.
The Enigma/Voyager/Odyssey features ‘floating box’ Highway-in-the-Sky (HITS) navigation. This option can be selected in the navigation menu, and you have the option of ignoring altitude (boxes automatically appear at your altitude).
HITS boxes will be activated any time you activate a Goto or Route.
3D GLS (GPS ILS) approaches are also achieved using HITS and a 3D runway depiction on the attitude page.
All MGL Avionics EFIS systems include 3D synthetic terrain, which can be enabled or disabled at will. You can even display 3D synthetic terrain without an attitude sensor installed (no attitude information is displayed), making this a great feature for those electing not to take the SP-4 attitude sensor.
Airports and runways are depicted on the terrain with airports and runway threshold labeled. Distances/times to airport are also shown.
The Enigma/Voyager/Odyssey comes with a comprehensive terrain awareness and warning system. Terrain data is stored on the SD card located in the front of the EFIS panel and is 1km resolution. 90m resolution terrain data will be available in chunks for select areas.
Terrain awareness is provided via the use of terrain data as the moving map background.
Also, the Terrain Look-ahead screen item allows you to view your projected flight path relative to the terrain.
Yellow is 1,000’ or less below your current altitude, and Red is at or above your present position.
The terrain warning setup menu allows you to set up your terrain warning system. It is setup to disable automatically in the landing mode by detecting RPM below a specified value or by detecting flap position in the landing mode. As with all alarm events in the Enigma, you can select on-screen warnings, voice alerts and external alarm lights.
You can also select an on-screen flashing terrain warning.
Yellow is 1,000’ or less below your current altitude, and Red is at or above your present position.
The Odyssey, Voyager and Enigma can monitor traffic from several sources via the RS-232 or ARINC 429 (Odyssey/Voyager only) interfaces, and will display traffic on the moving map page. Relative altitude is shown as well as the intruder’s ground track in certain cases.
The following systems are supported:
The Zaon PCAS (Portable Collision Avoidance System) is a popular portable traffic information system that can be used anywhere in the world and will track 3 intruders at a time using the other aircraft’s transponder replies.
Mode-S Transponder - TIS (Traffic Information Service) (Odyssey/Voyager only)
The TIS system operates only in certain areas in the United States and requires a Mode-S Transponder such as the Garmin GTX330.
TCAS is an active transponder-interrogation system.
European GPS-based system
Voice Alerts and Copilot Mode
The Enigma/Voyager/Odyssey has a built-in voice alert system. In the alarm setup you can choose On-screen alerts, EFIS onboard warning light, External Alarm Lamp Switch and Sound (Voice Alert) for each of the available alarm events. The EFIS ships with a full sound library for all the warning phrases, and an easy-to-use application that allows you to record the warning phrases in your own voice, if required.
Enigmas ‘Copilot Mode’ allows you to setup the EFIS to call out airspeeds whenever you get below a predetermined airspeed. You can select the time interval for these airspeed callouts.
Copilot Mode allows the pilot to keep his/her eyes outside the cockpit on landing and still keep a good awareness of airspeed.
Simulator and Designer
Enigma features a full-featured simulator that allows you to simulate just about all of the functions of the Enigma on your PC. Also, the simulator is used to design screen layouts if you so desire...
The Enigma/Voyager/Odyssey offers comprehensive engine monitoring for any engine. All engine data is captured via our RDAC (Remote Data Acquisition Computer) that mounts near the engine (in front of or behind the firewall). This data acquisition computer then sends all sender data to the Enigma display via 1 serial cable. No wiring harness for engine senders required!
There are 4 RDAC models, depending on your need:
- RDAC VD - All engine functions with 4-channels for thermocouples (CHT/EGT)
- RDAC VT - For turbine engines and with 4-channels for thermocouples (CHT/EGT)
- RDAC X-B - All engine functions with 12-channels for thermocouples (CHT/EGT)
- RDAC X-D - All engine functions with 12-channels for thermocouples and manifold pressure (MAP)
So, if you intend to monitor more than 2 cylinders of CHT/EGT, you need either the X-B (no manifold pressure) or the X-D (manifold pressure sensor onboard)..
Twin engine or extra sensor requirements? You can connect 2 RDACs to each EFIS.
- Maintenance Timers
- Oil Temperature
- Oil Pressure
- Fuel Pressure (if not using NTC CHT inputs)
- Water Temp (if required)
- Carb Ice (if required)
- Fuel level (1 or 2 with resistive senders)
- Fuel flow (using turbine sensor or fuel injector signal)
Whenever an engine parameter is exceeded an alarm will be initiated. The alarm can be setup to be any or all of the following:
RDAC Technical Details:
- On screen warning
- Flashing Enigma alert light
- External contact (panel warning light)
- Voice alert (which you can record yourself using the Sounds program)
- Four or twelve channel thermocouple amplifier, high resolution chopper stabilized system with full cold junction compensation and low voltage correction to laboratory standards.
- The inputs can accept K-type or J-type thermocouples (selectable via provided menu functions)

- LM335 sensor based temperature sender to indicate ice warning. The sender is normally fitted to the outside of a carburetor, in close proximity to the throttle slider or valve or in the intake airflow.
- The EMS included with the Enigma provides for a wide variety of engines and the display unit can be configured in many different ways to display the information required.
Attitude/Heading Reference System (AHRS)
The following 2 AHRS sensors can be connected to the Enigma/Voyager/Odyssey. They are connected to the Airtalk port in the rear of the EFIS display. If both sensors are connected, an RCA Y-connector can be used. Airtalk uses standard RCA cables/connectors available from your audio/video equipment store (6 foot length ships with each sensor).
