Abstract : Laboratory measurements were made on very high frequency (vhf), commercial airborne transceivers and Federal Aviation Administration (FAA) vhf ground transmitters and receivers. Characteristics of each unit were measured in order to determine suitability for data link application and to provide a data base for subsequent planning of vhf data link flight tests. Results show that Aeronautical Radio, Inc. (ARINC), transceivers are suitable data link devices and with minor modifications most FAA and general aviation transmitters and receivers tested are also suitable at the 2400 and 4800 bit per second rates.
