Problem 2 (30%; flight attitude): Consider a jet engine airplane with Drag Polar C = 0.04+0.5C, and lift characteristics C = 0.1a (a in degrees). While cruising for maximum range at an altitude of 8000m., it was determined to let the aircraft loiter for 30 minutes at this altitude (as in the case of waiting for airport clearance). The pilot decides to loiter with minimum fuel consumption. Determine by how many degrees- positive or negative - that the angle of attack needs to be changed.
