A Lear jet flying at 150 KCAS (assume no errors due to compressibility so let's assume 150 KEAS) at sea level on a standard day preparing to land and flying in a no flaps configuration. Weight is 12,000 lb and the wing area is 175 ft2.
a) What is the approximate Coefficient of Lift?
b) What is the Coefficient of Lift after lowering flaps but staying at the same airspeed?
c) What is the new coefficient of Lift on approach speed of 115 KEAS?
