MGL Vega EMS-1

The Vega EMS-1 is a 2 1/4 universal engine monitor colour display instrument. The EMS-1 contains all the necessary functionality to replace several engine monitoring instruments.

All information is displayed in an easy to read format on a high resolution wide viewing angle 1.8 1000cd/m2 sunlight readable colour display.

The EMS-1 light weight, small size and high level of functionality makes it an excellent choice for all types of engines.

The EMS-1 can also be interfaced via the CAN bus to an optional external RDAC unit (Remote Data Acquisition Computer). This allows for easier installation as the RDAC unit is normally mounted in the engine compartment.


  • Large 1.8 high resolution 160x128, sunlight readable, wide viewing angle, 1000 cd/m2 TFT LCD display

  • The engine display screen is automatically configured to optimize screen space depending on what engine parameters have been selected

  • Optional External RDAC (Remote Data Acquisition Computer) interfacing via the CAN bus

  • Standard 2 1/4 aircraft enclosure (can be front or rear mounted)

  • Rotary control plus 2 independent buttons for easy menu navigation and user input

  • An external output activates when a alarm condition has been reached

  • Includes a RS232 serial output for interfacing to external equipment e.g dataloggers etc.

  • Wide input supply voltage range of 8 to 30V DC with built in voltage reversal and over voltage protection for harsh electrical environments

  • 1 year limited warranty


  • Can measure up to 4 thermocouple channels using the internal electronics or up to 12 thermocouple channels using an optional external RDAC

  • EGT/CHT Temperatures can be displayed in C or F from -100C to 1200C (-148F to 2192F)

  • High accuracy: Built in thermocouple linearisation curves and cold junction compensation

  • Includes an EGT/CHT trend graph display of each thermocouple channel

  • Records maximum EGT/CHT temperature reached for each channel

  • Includes an engine leaning feature

  • Includes an engine cruise feature

  • Special Rotax 912/914 engine monitor mode utilising the standard built in Rotax NTC CHT probes


  • Single or dual RPM measurement

  • Includes a magneto check function

  • RPM can be displayed in RPM or in percentage

  • Records maximum RPM reached for each channel

Analog Inputs

  • Can measure up to 4 Analogue channels

  • Analogue channels are universal and can be configured to measure Pressure, Temperature or Current

  • Current measurement requires a MGL Avionics magnetic field or active current shunt

  • Pressure can be measured using standard automotive resistive senders (e.g. VDO 2, 5 and 10Bar), Rotax 4-20mA senders as well as voltage output pressure senders (e.g. UMA)

  • Temperature can be measured using standard automotive resistive senders (e.g. VDO, Westach) as well as the MGL Avionics precision LM335 semiconductor sensor

  • High accuracy: Built in linearsation curves for common senders

  • Analogue channels can be programmed to a user defined curve for custom senders

  • Supports the Rotax 4-20mA pressure sender as used in the 912/914 engines

  • Temperatures can be displayed in C or F

  • Pressure can be displayed in psi or bar

  • Records minimum and maximum values reached for each channel

Manifold Pressure

  • Manifold pressure can be displayed in millibar (mB) or in inches of Mercury ("Hg).

  • Records maximum MAP reached in permanent memory

  • MGL Avionics RDAC-XF MAP required


  • Displays both UTC (Zulu time) and local time

  • Time is maintained by an internal lithium battery which can be replaced by the user

  • Includes a settable Hobbs meter which is password protected

  • Includes an engine running and flight timer

  • Includes a programmable maintenance timer for scheduled routine engine maintenance

  • Provides a 50 entry flight log that stores the start time and duration of each of the last 50 flights. The flight timer can either be started automatically or by using a front push button


  • Can measure voltages up to 30V (compatible with both 12V and 24V aircraft supplies)

  • Contains a programmable low/high voltage alarm to automatically detect alternator failures and bad batteries

  • Records maximum and minimum Volts reached in permanent memory

Current (RDAC connection)

  • Uses the MGL Avionics magnetic field or active current shunt to measure the aircraft's current load.

  • Records maximum and minimum current reached in permanent memory
