- Summary:
- Daily are presented to show the extent to which the maximum lift coefficient and, consequently, the minimum speed of an airplane, as determined by flight tests, may vary with test conditions. The data show that CLmax may vary by as much as 14 percent, depending on the altitude and wing loading at which the tests are made, the position or motion of the propeller, and the rate at which the angle of attack is changing when the maximum lift coefficient is obtained. The variation of the maximum lift coefficient with these factors, which are under the control of the test engineer, shows the need of standardizing the test procedure. A further variation is shown with wing condtiions as affected by weathering and vibration, factors that cannot be completely controlled.
