Table 4.2-2: Wing Corrective Adjustments
Descriptions of how to perform these adjustments is given in the following paragraphs.
However, the amount of adjustment required is dependent upon the specific problem and
varies from wing to wing. Therefore, it is important to make only one change at a time. Make
a small change and then test the effect of those changes by flying the wing. It is best if these
adjustments are made by someone with wing tuning experience since it takes practice and
patience to tune a wing properly.
