I had found out that there was a new software version for my Advanced Flight Systems EF/EM Display so I went to the AFS web site and down loaded the software file. I purchased a SD card and copied the software to the card. Then I installed the SD card in the Display's SD card slot and powered up the Display. The new software version loaded. Next I carried out the Trutrk autopilot ground check out. I found out that I'll need to install a jumper at the controller connector to reverse the direction of the pitch servo. Lastly I carried out the MD-RA mandated fuel flow report by lowering the aircraft tail to the ground for a maximum angle of climb attitude, then lowering the fuel quantity in the tank to a minimum level followed by timing the length of time it took to pump 1 US gallon of fuel. It took exactly 2 minutes to pump 1 US gallon. Therefore the fuel flow rate works out to 30 US gallons per hour. The MD-RA mandate for fuel pump fed systems is 125% of the maximum fuel flow for the installed engine at take off power. I have an O-360 installed. This engine as per Lycoming consumes 14 gallons per hour at takeoff power at sea level. Therefore I require a minimum flow capacity of 17.5 gallons per hour. The demonstated flow rate of 30 gallons per hour therefore exceeds the minimum requirement by a healthy margin.
