Weather has a tremendous impact on aviation operations. A study of National Transportation Safety Board accident reports from the years 1994 through 2006 conducted by the Office of the Federal Coordinator for Meteorological Services and Supporting Research revealed that 20 percent of aviation accidents and 23 percent of fatal aviation accidents were weather related. Weather delays account for 70 percent of the $41 billion annual cost of air traffic delays within the United States National Airspace System (NAS), or $28 billion annually. Approximately two thirds ($19 billion) of these delays are considered to be avoidable. The Weather--Air Traffic Management (ATM) Integration Working Group (WAIWG) of the NAS Operations Subcommittee of the Federal Aviation Administration's (FAA's) Research, Engineering and Development Advisory Committee (REDAC) conducted a 12-month study to examine the potential benefits of integrating weather and ATM. Although this subcommittee was focused on the benefits of weather integration, it is likely that significant safety benefits will result from effective integration of weather into ATM decisions though they have not been calculated. The report of this committee made several recommendations regarding integration of weather and the potential for weather integration to help reduce delays. |
