History• Aircraft Landing Aids

– 1920’s: Airport Lighting (Beacon)– 1929: four-course radio range, where the pilot was guided

by the strength of Morse code signals.– 1930’s: Approach Lighting(Glide path & Glide slope)– 1938’s: ILS– 1940’s: Slope-line approach system– 1948, distance measuring equipment (DME)– 1950’s: development of radar during World War II led to

the development of a new precision-beam landing aid called ground control approach (GCA).

– 1980’s: Microwave Landing System, 1994 halted by FAA– 1994: Global Positioning System
