The Eagle EMS also requires its own Battery (not shown above) which you will need to provide.




Speed Sensors: Two identical speed sensors are installed in place of existing magnetos.  They are driven using the existing magneto drive gearing.


Throttle Body: This component is installed in place of the existing Fuel Injection Servo or Carburetor.  It consists of a throttle butterfly valve with throttle position switch, two inlet air temperature sensors, and two manifold pressure taps.

Distributor Block: A distributor block, which incorporates a ten-micron replaceable filter element and redundant fuel pressure sensors.

Fuel Injectors (4):  These components are aviation quality pulse width modulated injectors.  They can be mounted in the existing injector ports, or the intake tubes.

Electronic Control Unit (ECU):  Contains two redundant, independent systems with all necessary circuitry and software to allow control of all system functions.  Housed inside the ECU are the manifold pressure sensors.


High Voltage Ignition Coils:  Two identical ignition coils with shielded ignition harnesses are installed in a location near the spark plugs on the engine mount.

Battery: You need to provide a battery for the Eagle EMS.  The Eagle's battery will be monitored and charged by the power management module.

The Eagle EMS draws approximately 1.8 amps.  The battery for the Eagle needs to provide you with enough time to land safely in case of main electrical system failure.  The battery's size and weight also need to be suitable for your airplane.  Therefore, you need to provide the battery, and we leave the specific selection up to you.

Power Management Module: Continuously monitors the aircraft power, maintains the Eagle's battery and automatically switches to backup power if necessary.

Cockpit Annunciator:  The cockpit annunciator serves to inform the pilot about problems with the EMS system, much the same way as the "Check Engine" light in a car.  The panel will provide system status and warnings if the system switches to a backup mode.
