From the Editor in Chief: Air System Information Management
نویسنده
چکیده
Iflew to Washington, DC, last week — a trip rich in distributed information management. Buying tickets, at the gate, in flight, landing, and at the baggage claim, myriad messages about my reservation, the weather, our flight plans, gates, bags, and so forth flew among a variety of travel agency, airline, and US Federal Aviation Administration (FAA) computers and personnel. By and large, each kind of information ran on a particular application, often specialized to its own data formats and communications network. I went to Washington to attend an FAA meeting on System-Wide Information Management (SWIM) for the National Airspace System (www.nas -architecture.faa.gov/Tutorials/NAS101.cfm). NAS (and its information infrastructure, SWIM) is an attempt to bring greater regularity, efficiency, and uniformity to the collection of stovepipe applications now used to manage air traffic. Current systems hold information about flight plans, flight trajectories, weather, air turbulence, current and forecast weather, radar summaries, hazardous condition warnings, airport and airspace capacity constraints, temporary flight restrictions, and so forth. Information moving among these stovepipe systems is usually mediated by people (for example, air traffic controllers) or single-purpose applications. People, whose intelligence is critical for difficult tasks and unusual circumstances, are not as efficient as computers for tasks that can be automated. Better information sharing can lead to higher system capacity, more efficient utilization, and safer operations. Better information sharing through greater automation is possible, though not necessarily easy.
