The NextGen Joint Planning and Development Office (JPDO) and the NextGen partner agencies are planning the evolution of the entire National Airspace System (NAS) over the next two decades. The weather communities within the National Oceanic and Atmospheric Administration (NOAA), the Federal Aviation Administration (FAA), and the Department of Defense (DoD) have developed this Plan to meet the user's needs. A complementary follow-on effort, to describe a Plan that describes a common weather reference and its translation and integration into evolving operational decision-support, will also be developed. The Plans will be merged in 2010. In the NextGen concept, weather information used by ATM decision-makers will come from a net-centric, virtual, data repository of aviation weather data, referred to as the four-dimensional weather data cube. This concept allows each agency to leverage and merge their existing agency-specific efforts and aviation-weather requirements into a mutually supportable national and eventually global, construct. This Federal effort addresses a way to combine public and private sector aviation weather needs into the ATM process as well as allowing each agency to maintain various independent capabilities consistent with their own weather needs. A foundational element of this Plan builds upon and takes advantage of evolving information technology advances. In order to achieve this Plan for weather access and use, the weather community must address certain unmet aviation weather user needs that exist today. If not addressed, many, if not all of these unmet needs will remain during any transitional ATM phase with increasing consequence. End-state ATM capabilities and performance-based goals will be greatly compromised without the envisioned weather infrastructure and support as described in this Plan. In short, weather access and use must change to support more performance-based operations as future NextGen capabilities are realized. |
