TLDR
A theoretical approach to implement new weather information technologies while addressing the National Airspace System as an evolvingsystem with Weather Information as one of its subsystems is set forth.Abstract:
The capacity of the National Airspace System is being stressed due to the limits of current technologies. Because of this, the FAA and NASA are working to develop new technologies to increase the system's capacity which enhancing safety. Adverse weather has been determined to be a major factor in aircraft accidents and fatalities and the FAA and NASA have developed programs to improve aviation weather information technologies and communications for system users The Aviation Weather Information Element of the Weather Accident Prevention Project of NASA's Aviation Safety Program is currently working to develop these technologies in coordination with the FAA and industry. This paper sets forth a theoretical approach to implement these new technologies while addressing the National Airspace System (NAS) as an evolving system with Weather Information as one of its subSystems. With this approach in place, system users will be able to acquire the type of weather information that is needed based upon the type of decision-making situation and condition that is encountered. The theoretical approach addressed in this paper takes the form of a model for weather information implementation. This model addresses the use of weather information in three decision-making situations, based upon the system user's operational perspective. The model also addresses two decision-making conditions, which are based upon the need for collaboration due to the level of support offered by the weather information provided by each new product or technology. The model is proposed for use in weather information implementation in order to provide a systems approach to the NAS. Enhancements to the NAS collaborative decision-making capabilities are also suggested.read more

An Integrated Decision-Making Model for Categorizing Weather Products and Decision AIDS
Peter D. Elgin,Rickey P. Thomas +1 more
TL;DR: In this article, three naturalistic decision-making theories were integrated to provide an understanding of the levels of decision making incorporated in three operational situations and two conditions, and a graphical interface was described that affords intuitive selection of the appropriate weather product relative to the pilot s current flight situation.
Concept of Operations for the NASA Weather Accident Prevention (WxAP) Project
TL;DR: The Concept of operations document provides the basis for the WxAP project to develop requirements based on the operational needs of the system users, and provides the scenarios that the flight crews, airline operations centers, air traffic control, and flight service stations utilize to reduce weather related accidents.
Redesigning the national airspace system for sustainability
TL;DR: An independent assessment of technologies and policies for the U. S. National Airspace System (NAS) was conducted to guide future investments and improvements in the NAS, identifying choke points that impede air travel, and recommended policy decisions for NAS stakeholders.
