It should also be modular and flexible, to allow users to incorporate other tools. Accessibility: EDS should be PC based. 9 Completed Uncertainty: EDS should be able to manage uncertainties Ongoing: Developing detailed within its modeling capacity. 9 fidelity management system Predictive: EDS should have a predictive capability as part Ongoing: Future technologies of its functionality. 9 will be modeled with expert driven, industry involvement Availability: EDS inputs must be nonproprietary. Ongoing: Based on publicly 9 available information Coordination: EDS must be able to interface with existing Ongoing: Initial Capability, tools and the AEDT. 9 improved capability coming 9 Environmental Design Space (EDS) Overview Federal Aviation 9 December 6-8, 2006 Administration TRB Guidance 9= good progress 9= partial progress EDS Development Process Status Notes Extensible: EDS should be able to accommodate Not a current priority additional and newer aircraft types, such as 9 helicopters and general aviation and various military aircraft. Improved Emissions: EDS should be able to Ongoing: Working improved accommodate additional emissions species and 9 and additional emissions fates that have not been subject to analysis in the capabilities past. Interaction: EDS should be developed with active Ongoing: EDS Technical stakeholder involvement 9 Advisory board and industry collaboration Validation: EDS development process should Ongoing: Collaboration with include a validation plan that involves input from a 9 GE, P&W, and Boeing, variety of stakeholders. looking for additional partners Coordination: The development process should EDS, APMT, AEDT teams assure that EDS and the AEDT are developed on 9 have common members, parallel tracks. interaction 10 Environmental Design Space (EDS) Overview Federal Aviation 10 December 6-8, 2006 Administration TRB Guidance 9= good progress 9= partial progress Technical Initiatives Involving AEDT Status Notes Design and the EDS Component Distributable: Although not all NASA models can We use surrogate models be distributed, this work should result in a product to protect NASA models that is distributable. Consolidation of the NASA 9 and information and models should take this distribution requirement enable distribution into consideration. While certain individual components have already Ongoing: Developing been tested independently, the research should detailed fidelity examine new vehicles under EDS so that the final 9 management system tool will surpass and leverage existing capabilities. The committee recommends that FAA clarify the Ongoing: Continuing different roles of EDS outputs versus databases of interactions with existing aircraft to help stakeholders understand 9 stakeholders through the uses of the model in different contexts.
