hehe Posted November 9, 2018 Share Posted November 9, 2018 I would say no especially if you are going off of type certificate (FAA) data. Submit an engineering request to FMS and see what they say. 1 Quote Link to comment Share on other sites More sharing options...

pjvr99 Posted November 9, 2018 Share Posted November 9, 2018 2 things will happen here: 1- you will lose the commercial (civilian) certification for the D22 2- you will have no fuel flow indication. The T56 engine uses a 28v DC power supply for the ff transmitter and indicators, while the D22 uses a 115v 400hz power supply. The wiring and connectors are completely different. In my opinion this would be a completely wasted excercise, not to mention the expense of recertifying the D22 again 1 Quote Link to comment Share on other sites More sharing options...

AerexAvionics.com Posted January 28, 2019 Share Posted January 28, 2019 Go to AerexAvionics.com to learn about the Fuel Flow Interface used on the C-130 and other platforms for many years to access the fuel data from the fuel flow transmitter to the FMS. The Interface converts the 2nd Harmonic to DC or AC Linear for the FMS to receive the fuel data. Copy of the STC included in the install manual with a one time use agreement. DERCO is a distributor of the unit or MROs can contact Aerex directly. Hope this helps with your modification research. Quote Link to comment Share on other sites More sharing options...
