Abstract:This report documents the results of the first Federal Aviation Administration
(FAA) manned simulation study designed to demonstrate and quantify some of the
benefits that would accrue to National Airspace System (NAS) users in return for
equipping aircraft to receive domestic, two-way Data Link Air Traffic Control
(ATC) services. Air traffic controllers, ATC supervisors, and professional
pilots participated in high fidelity simulation tests in which a combined Data
Link and voice radio communication system was used to control traffic in en
route airspace. The study demonstrated that controllers using two-way Data Link
were able to provide ATC services that improved en route sector productivity and
efficiency. These effects were reflected in reduced aircraft ground delay,
flight time, and flight distance in comparison to a current operational
environment using only voice radio communications. In all cases, the results
were achieved with a margin of safety which met, or exceeded, current ATC
standards, and with no indication of excessive controller workload. Economic
cost savings associated with the findings were computed to determine the
potential magnitude of two-way Data Link's impact and its significance to NAS
users. 125p.
