Class 40(7) In a radio-navigation system presenting information necessary for the landing of the craft to the pilot thereof two ground to craft radio channels are used and the information conveyed by one is presented visually and that conveyed by the other presented aurally. In a preferred embodiment a pulse radar of the height-finding type is used on the ground and obtains echoes from the craft to give a range/height display on a cathode ray tube. This display, with distance markings and an ideal glide path indication superimposed, is televised to the craft for display to the pilot. Azimuthal guidance is provided by means of sequential overlapping-beam ground beacon whose beams are modulated with interrelated series of dots and dashes respectively. The signals from this beacon are received and presented aurally to the pilot. The beacon may include means for replacing the dot and dash modulation by speech modulation for communication or "Ground Control Approach" (G.C.A.) purposes. In an alternative azimuth guidance arrangement a second ground radar is provided scanning in azimuth to give a P.P.I. display. This radar includes an azimuth determining strobe which controls the sense and depth of dot-dash modulation sent to the craft by a communication channel and there used to give exactly the same kind of aurally presented information as in the previous embodiment. When the craft is on the runway approach path the strobe controls the modulator to give equal strength dots and dashes which form a continuous signal. The modulator may be monitored at the ground station by means of a suitable meter, the face of which can be included in the picture televised to the craft.
