Without Engine Sensors or Harness

Part No:

Manufacturer: DYNON AVIONICS

The EMS-D10 is ergonomically engineered to blend traditional analog gauges with newer digital technologies to provide a user-friendly instrument that enhances safety and peace of mind. With up to 27 separate inputs available, the pilot's workload is significantly reduced as the EMS-D10 continuously monitors all sensor inputs for the powerplant, fuel and other miscellaneous systems and immediately annunciates any abnormality requiring attention.

A multi-page display environment provides pilots with an excellent systems overview coupled with the added capability of presenting additional detail upon demand to optimize overall management of the various systems. Each of the color graphic screen presentations promotes easy visual scanning for interpretation of the current measurements relative to their normal/abnormal operational limits.

New Design:

While the EMS-D10 looks identical to Dynon's popular EFIS-D10 series of Electronic Flight Information Systems, it is not the same instrument nor simply a software upgrade but a totally new and separate dedicated instrument. To keep the look and feel of the EFIS series, the EMS-D10 utilizes the identical sunlight visible, color display, keypad and bezel that preserves the look and feel while additionally allowing greater panel uniformity. Once past the common user interface, the electronics support are very different between the EFIS series and EMS-D10 engine monitoring system.


Dynon offers a variety of probes to accompany the EMS-D10 instrument with very attractive package pricing. The probes initially offered by Dynon are optimized to support Lycoming engines. Probes unique to other engines like Rotax, Subaru, Jabiru and others will also be available from Dynon in the near future.

Airplanes with existing engine sensors may already be compatible with the Dynon EMS-D10 system. The EMS-D10 was designed with the intention of retrofitting some of the more popular non graphical systems already in existence like Grand Rapids EIS systems. While not 100% backward compatible, replacement costs are minimized to the extent possible. Please review the specifications and sensors charts on this website for additional detail.
