The EMS-D120 is a large screen Engine Monitoring System (EMS) that blends traditional analog gauges with newer digital technologies. The EMS-D120 replaces up to 16 different types of gauges which are displayed on a stunning 7?diagonal color screen. The sunlight readable, color display and softkey menu system result in a user-friendly instrument that enhances overall safety and peace of mind.

What makes the EMS-D120 so powerful is its ability to continuously monitor up to 27 available sensor inputs that cover the engine, fuel and other miscellaneous systems and annunciate any abnormality immediately upon detection. This constant scan significantly reduces the pilots workload while providing a more thorough and consistent review.

A split-screen display environment provides pilots with an excellent overview of the system coupled with additional pages of auxiliary information all available upon demand. Each of the color graphic pages are designed to promote easy visual scanning for interpretation of the current measurements relative to their normal/abnormal operational limits.

The EMS-D120 key features include leaning via EGT peak detection, fuel computer, user-defined alarm limited via EGT peak detection, fuel computer, user-defined alarm limits and ranges, audio & visual alarms, user-configurable pages, simple setup, English or Metric measurement units, system clock, contact inputs, timers and user-friendly soft key menus.

The 854 x 480 high resolution LCD affords split-screen partitioning to display two pages simultaneously. Many of the pages provided offer a high degree of user-defined configurability to accommodate different engine types and pilot preferences. Each screen is easily called up via Hotkey buttons that provide quick access.

When wired to other Dynon instruments via the Dynon Smart Avionics Bus (DSAB), the EMS-D120 can additionally display their data whenever called for by the pilot.

The price includes the instrument, a convenient mounting tray, three year warranty and free lifetime software updates available from Dynon's website. Reconfigured engine probe harness packages are available on an optional basis for several of the popular engines in the market. Individual probes are also available to configure other engine systems.

Super-Bright Screen Option
Dynon now offers an 800 unit super-bright screen option for its EFIS-D100, EMS-D120 and FlightDEK-D180. The enhanced sunlight readability, 854 x 480 resolution and night dimming capability deliver an impressive view no matter how you look at it.

Shock Cooling & Span Alarms
All EMS-based instruments now offer CHT shock colling and CHT span alarms to protect from damaging the engine.

Flap & Trim Indicators
Dynon has added flap and trim indications to all EMS-based products. They can be selected and arranged in a location of the user's choosing.

This degree of engine specific and pilot preferential customization when combined with a multi-page type of display and pilot configured checklists all add up to provide a unique presentation tailored to fit almost any need.

Airplanes with existing engine sensors may already be compatible with the Dynon EMS-D120 system. The EMS-D120 was designed with the intention of retrofitting some of the previously popular, non graphical systems like Grand Rapids EIS systems and Rocky Mountain Inc, Micro Monitors. While not 100% backward compatible, replacement costs are minimized to the extent possible.

Data Logging
The EMS can now log data internally for later retrieval and analysis. Up to 3500 records can be stored with each record containing all EMS sensors plus the Hobbs Time and Tach Time. Pilots can enable or disable the data logging function and store data in 1, 10 or 60 second intervals. Pilots can manually start and stop the logging function to capture specific flight conditions of interest, and also manually mark points in time to take a closer look at

% Power
Unlike many other implementations of this feature, our % power reading is not an estimate. It uses all of the data that engine manufacturers publish in their power charts, including altitude. Because of the complexity of doing this calculation correctly, this powerful feature requires an EFIS and EMS (or a FlightDEK-D180), OAT, and fuel flow sensor. It will only initially be available for the following engines: Lycoming O/IO-320, Lycoming O/IO-540, Lycoming O/IO-360, Continental IO-520, Continental IO-550.

Peak Condition Detection
This feature informs the pilot whether the engine is rich or lean of peak whenever the EMS is operating in Lean Mode. This feature requires a fuel flow sender.

Fuel Tank Fill Autodetect
Automatically notices if the fuel level has increased in any of the fuel tanks, which in turn will prompt the pilot to adjust the flow-based fuel computer state (when equipped with the fuel flow sender).

Analog Fuel Flow Dial
By popular request, the fuel pressure gauge on the main EMS display has been exchanged with fuel flow. Fuel pressure is also available as an info bar.
