The form drag coefficient of a certain light aircraft is equal to 0.011. Its skin friction drag coefficient is 0.016. Determine its lift-to-drag ratio (nearest hundredths) while flying at the speed for minimum power required if its interference drag is 7 percent of its profile drag. The aircraft has rectangular wing with an aspect ratio of 7.01. Assume a a span efficiency factor of 0.91.
