A path for guiding an aircraft on the ground is divided into a plurality of particular sections (D), a multitude of loop coils (l) of a predetermined shape are buried in these sections continuously. The aircraft is detected (3) continuously while discriminating it from other objects on the basis of the change in self-inductance of the loop coils accompanying the passage of the aircraft, and permission of either entry or no entry into a particular section (D) is indicated (4, 7, 6) for a succeeding aircraft depending upon the presence or absence of an aircraft in the particular section (D), thus providing an apparatus for guiding an aircraft on the ground comprising fail-safe devices which generate no output when they are defective.
