Mass and Balance







I love this task....because it means you're nearly ready to aviate!



With zero fuel and full oil we positioned ZU-FDI on the 3 scales with the canopy sills level. Using a plumbbob and a long tape measure we determined the distance between the wing leading edge and the main wheel centreline and the tailwheel centreline. Determining the exact position of the humans and fuel is normally a little difficult so this time I climbed into the aircraft whilst it was on the scales (not that easy!) and from the readings worked back to obtain the exact moment arm. I did the same with the fuel. See spreadsheet below.
