Definition Radio: the transmission and reception of RADIO WAVES, especially those carrying audio messages. Navigation: The process of plan and direct the route of aircraft by using INSTRUMENTS or maps.

Definition Aircraft Communication – The delivery of information to or from aircraft by RADIO or SIGNALS. NASA Thesaurus, Washington, DC Air Navigation – The action of plotting and directing the route of an aircraft through the air from one place to another. Adapted from the United States Air Force Dictionary. A study of basic principles of the navigation systems used on modern aircraft including the “glass cockpit” and the general theory of navigation systems will be addressed, along with specific investigation into ADF VOR/localizer, glide slope, marker beacon systems, aircraft drawings and various manufacturer’s support manuals will be used.

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
