Thread: Fuel Guage

    Fuel Guage

    This morning I carefully calibrated the fuel tanks in 2 gallon increments at ground and flight attitudes (tail dragger). Everything seemed normal and the values steadily decreased as the tank filled up, but when I was done both tanks read 0. Empty was 926 for both ground and flight, but when I changed ground to 927 on empty the tanks read correctly on the ground, but in flight they still read 0.

    Found the problem. The sensor didn't register anything at 2 gallons and apparently the formula to interpolate the data doesn't like that. When I changed the 2 gallon settings to be lower than 0, everything worked fine.
