How data link communication might affect controller workload on a terminal option

摘要

The Aeronautical Data Link System (ADLS) is being developed as part of the Federal Aviation Administration's modernization plan to improve safety, reduce delays, and increase the efficiency of resource utilization,. Terminal Data Link (TDL), an ADLS application, will provide five services to support Controller/Pilot Data Link Communication (Automatic Dependent Surveillance Panel, 1996). These services will require controller use of a keyboard-input module to communicate with pilots. At terminal radar approach control (TRACON) facilities, the keyboard-input module includes an ABCstyle alphanumeric keyboard and a trackball
