It has not yet been decided how the aircraft will be powered but the following is known: Wing area = 75 m2 Maximum cruise speed = 540 kmh EAS Drag polar is estimated as Cp = 0.025 +0.05CZ For a cruise mass of 25000 kg, find: (i) the minimum drag speed (EAS); [86.89 m/s] (ii) the minimum power speed (EAS); [66.02 m/s] (iii) the lift-to-drag ratio at the maximum cruise speed; [8.53] a 26
