    Do not install an Experimental EDM-350 in a certified aircraft. If the EDM-350 is configured to monitor the aircrafts fuel tanks, the EDM-350 must be calibrated to the aircraft fuel system and the EDM-350's accuracy must be verified before flying the aircraft.
  • Page 3 POH for every function displayed on the EDM-350. The use of the EDM-350 requires recurring training for any pilot who will be flying the aircraft in which it is installed. Recurring training should include reading the EDM-350 Installation Manual and seeking a flight instructor for proper interpretation of information being displayed to the pilot.
  • Page 4 4. In Flight - Make the EDM-350 part of your normal instrument scan. Crosscheck the fuel levels displayed on the EDM-350 with your flight plan at each leg of the flight or every 30 minutes (whichever happens first). If there is a discrepancy, land the aircraft at the nearest airport and verify the fuel levels.

  • Page 5: Operation And Abbreviations

    Date 7-10-2021 3. Operation and Abbreviations The EDM-350 is a combined electronic indicating system which simultaneously displays to the pilot powerplant and aircraft systems operating parameters. It includes the following indicating systems; replacing all previous digital and/or analog instruments: Message Area Abbreviation in parenthesis. (X)* denotes cylinder No.

    4. Remote Alarm Light EDM 350 The remote alarm light is a Red or Yellow light depending on the alarm condition. The EDM-350 incorporates a single light that alerts the pilot that a problem existing within the engine. It is a single light that changes color with condition and the label associated with the light must be lit by a post light or such that you can see the word “ENGINE”.

EDM Display Installation Choose the Proper Installation Location The display is best located within the natural scan and easy reach of the pilot. The recommended mounting location is defined as the distance from the vertical centerline of the Primary Flight Instruments to the outer edge of the further most gauge displayed on the EDM.

  • Page 11: Pressurized Aircraft Wire Routing

    An alternate method for a cannon connector is to use existing wires in the aircraft going thru the pressure bulkhead. The EDM-350 replaces the RPM, MAP, CHT, Oil Temperature, Oil Pressure Fuel Pressure, Fuel Flow and TIT gauges which have wires going thru the pressure bulkhead. Making a new hole in the pressure bulkhead is beyond the scope of this document and should be done according to best practices.

    The most common installation problems are related to poor quality terminations. 9.1 Wiring Markings The EDM-350 is supplied with special Teflon insulated Chromel-Alumel factory assembled wiring harness configured for the correct number of cylinders. The wire harness is marked E1= EGT-1, C1= CHT-1, etc.
