Level the aircraft as per the weight and balance section of the landplane handbook.
Place the scales under all 4 wheels. Place whatever blocking is required under the mail gears to level the aircraft.
Drop a plumb bob from the face of the firewall and mark the floor. This mark is 0.0 in the calculations.
Measure the distance from 0.0 to each nose wheel center. This is X1 and X2.
Measure the distance from 0.0 to each main wheel center. This is Y1 and Y2.
If the floats are seaplane floats, the scales go under the step point in the rear and a point towards the front of the
float. These distances are measured and become the same X and Y as for the amphibian.
Use this table for the calculations:
