Brief Description: Fuel quantity indicating system calibration
After getting in touch with Tech Support at Princeton Electronics the manufacturer of my capacitance fuel quantity adapter I had a better idea of how to calibrate the "zero fuel" level for the adapter. I also contacted Advanced Flight Systems for added information on the Engine Monitor fuel calibration procedure. With this information in hand I headed back to Stoney Creek Airport to carry out the fuel quantity indicating system calibration. After setting the fuel quantity adapter "zero fuel" level point I poured in measured amounts of fuel into the fuel tanks and adjusted the calibration points in the engine monitor fuel tank calibration page. First I did the left tank, then pumped fuel back into my gas cans so I could do the same for the right tank. While pumping fuel I also found a fuel leak at the inlet to the engine primer so I rectified that. I also took note that the fuel flow transducer was working as it indicated 29.6 gallons per hour. I also timed a one gallon amount to verify the fuel flow rate and to see if the fuel flow transducer was measuring accurately as well as verifying I well exceed the required fuel flow rate for the installed engine as required by regulations. With the fuel quantity indicating system calibrated I rewired the fuel quanity adapter power lead so it now feeds off the essential buss rather than the hot battery buss. Lastly I had noted that there were still some air bubbles in the brake lines so I did one more brake system servicing to get the air out. Then I called it a day.
