I borrowed a set aircraft scales and with help from my supervisor we identified weight on each wheel, and also position. Two spirit levels was used to ensure that aircraft was in level. Adjusted with thin plywood sheets under scales. Position of leading edge, mainwheels and nosewheel measured. Coolant and oil level checked. Fueltanks drained and than filled with one liter fuel in each. As defined in Kennblatt. Results Left MW 96Kg Arm 767 mm Right MW 93,5 Kg 767 mm Nosewheel 112,5Kg -518 mm Total 302 Kg C/G 288 mm (empty 250-350mm) Depending on pilot weight and fuellevel C/G can vary between 345 and 425mm (demand 300-450 mm).
