Question: The short-period motion of a jet fighter aircraft can be described by the equations of Example 2.6-1. The following are typical values of the equation coefficients for a modern open-loop-unstable configuration flying at an altitude of 5,000 ft and an airspeed of 650 ft/s (neglecting flap effects):
(a) Plot the root locus for pitch-rate feedback to the elevator with both positive and negative feedback gains.
(b) Repeat (a) for angle-of-attack feedback to the elevator.
(c) Plot the open-loop frequency responses of pitch rate and angle of attack to elevator inputs.
(d) Generate the corresponding Nyquist plots.
