1. Consider the LTV Vought A-7 data indicated below for three flight conditions where H denotes altitude and V denotes velocity. (Introduction to Aircraft Flight Mechanics, T. R. Yechout, 2003). Also consider the pure rolling model indicated below. with - L = L5, SA L = -4.401 1/s = -1.295 1/s L Lo = F -2.956 1/s LSA Flight phase category A B LSA = +28.46 1/s for (H,V) = (00,000 ft, 670 ft/s) LSA = +7.859 1/s for (H,V) = (35,000 ft, 584 ft/s) +14.24 1/s for (H,V)3 = (35,000 ft, 876 ft/s) a) Compute decay rate o, time constant t, and amplitude 3 for an aileron step input 8 = +3 deg for flight condition condition (H.V). b) Consider the A-7 and associated flight condition to be Class IV and Category B.
