PROBLEM TO BE SOLVED: To provide an automatic guidance device working on a hybrid navigation system, whereby a high precision flying control is performed using a drift angle in coupling as well with the radio navigation and AFCS as with the inertial navigation. SOLUTION: The course deviation angleαbetween the fuselage-land station direction and the set course is multiplied by the gaing k, followed by integration by an integrator (1/S) so that a presumptive drift angleθ' is determined. The signal obtained by subtracting the drift angle from the course error angleβbetween the flying course and set course is fed to a controller, and thereby the flying control is conducted. The drift angleθgiven by an inertial navigation device 10 is fed to a terminal A of a changeover device 11 while the presumptive drift angleθ' given by the integrator (1/S) is fed to another terminal B which are changed over in case of failure, whereby the control is executed normally using an accurate drift angleθfrom the terminal A, and when the inertial navigation device 10 is in failure, using the presumptive drift angleθ' from the terminal B in the same manner as conventional.
