Question

The RV-4, a single engine 2-seat light aircraft, has a span of 7.1 meters, an aspect ratio of 5.5, and a span efficiency factor of .65. If the aircraft is flying at a velocity of 260 km/hour at an altitude of 2,000 meters

(a) What is the induced drag when the total weight is 5,700N?

        (b) What is the induced drag with a velocity of 90 km/hour (the approximate stalling speed)?
