The flight path transition control apparatus provides a roll attitude command to control the aircraft to execute an exponential transition path to a predetermined course in accordance with the exponential control law Y+KY where Y is the lateral displacement of the aircraft from the predetermined course, Y is the rate of change of the lateral displacement and K is a time constant of the system. A predictive roll command phi p is generated in accordance with <IMAGE> where Vg is the aircraft ground speed, TAE is the track angle error of the aircraft with respect to the predetermined course, TAE0 is the track angle error of the aircraft with respect to the predetermined course at capture maneuver initiation, g is the gravitational constant, and t is the elapsed time following capture initiation. The predictive roll command phi p is combined with the exponential control law to provide the aircraft roll attitude command phi c= phi p+Y+KY to control the aircraft to execute the exponential transition path in capturing the predetermined course.
