A Cessna 172 aircraft is flying along at an estimated in-flight weight of 953kg and an air speed of 120 knots (222 km/hr) at 2000 feet where the air density is 1.114 kg/m3. The pilot is flying a long cross-country flight. When flying over Echuca on the way back to Moorabbin (235 km left to fly), the pilot notices from the fuel gauge that only 8 gallons of usable fuel remain in the tanks. The engineering characteristics of the aircraft are given below: • Wing span, b is 11 m. Wing area, S is 16.2 m2 • Parasite drag coefficient of aircraft, CDo is 0.02 • Average propeller efficiency ip is 0.85 . Oswald's efficiency factor, e is 0.81 • Engine-specific fuel consumption, Cb is 0.2 kg/hp/hour Answer the questions below: a. The operating lift coefficient of the wing C₁ b. The induced drag coefficient Cp; and the total drag coefficient Cp A Cessna 172 aircraft is flying along at an estimated in-flight weight of 953kg and an air speed of 120 knots (222 km/hr) at 2000 feet where the air density is 1.114 kg/m3.
