Abstract : A semi-automatic guidance control system for landing aircraft is already in use today, in both military and civilian air traffic control. The following designations are in use: Flight Reference System, Director System, Flight System, Command Guidance Installation, and Flight Command Installation. A description of the interconnections and relationships of the semi- and fully-automatic control systems includes a diagram showing the sequence of control instruments. These include the navigation and computer-controlled positioning instruments and the display instrumentation for the pilot to follow in the semi-automatic landing system, or the alternate mechanized instrument landing system for fully automatic landing. Instrumentation and guidance methods in the semi-automatic system are described, utilizing essentially the artificial horizon display instrumentation with radio-beam locating techniques for the correct positioning of the aircraft by the pilot in approaching the landing field. The fully automatic landing system involves similar ground-based navigational and aircraft-positioning equipment augmented by an automatic pilot mechanism aboard the aircraft. The following aspects are discussed: (1) two complex communication zones, involving the automatic landing approach zone and landing zone, (2) the problem of adapting automatic pilots now in use to the requirements of automatic landings.
