eeds, is such VL* M.P.H.x Ft Fig. 8.—Change in L. with change in VL. that serious errors may be introduced. It is, therefore, possible that the values given in report No. 70 of lift on the full size airplane are no closer than 5% and that the corresponding drag values may be 20% in error.4… … VL = M.P.H.x Ft. stream velocity obtained under climbingy Fig. P.—Change in D0 with change in VL. conditions. The absolute lift and drag coefficients and the -p ratio are plotted against the scale of test in Figs. 8, 9, and 10, respectively. The scale VL is expressed in both metric and English…
