FIELD EVALUATION OF DATA LINK SERVICES FOR GENERAL AVIATIONt

摘要

With the sponsorship of the Federal Aviation Administration, MIT Lincoln Laboratory has developed data link traffic and weather services for general aviation: The Traffic Information Service (TIS) displays ground-based traffic information, Graphical Weather Service (GWS) disseminates graphical precipitation maps, and Text Weather Service (TWS) provides surface observations and terminal forecasts.rnDevelopment of the data link applications has now reached the field evaluation stage. Plans are to equip a limited number of light aircraft with the data link avionics for a six-month period. The services are provided via the Dulles Mode S sensor and a ground transmit/receive station installed in Frederick, MD. Pilot evaluators have access to the services on structured evaluation flights and routine business flights. Evaluators will assess each of the services, the training procedures, and the cockpit interface.
