Tools and Analysis Roadmap

Objective: 

Develop a multi-year schedule for the development and use of the environmental modeling assessment tools

Ensure clear linkage of research efforts to AEE analysis needs

Install environmental modeling assessment tools in the AEE modeling lab 

Develop user manuals for the environmental modeling assessment tools

Process:

Identify analyses and deadlines for deliverables, (e.g., CLEEN Tech Assessment, Goals Analysis, CAEP) 

Create flowchart of tools and data that are required for each analysis

Link to other AEE roadmaps, as needed

Gather information on:

Existing linkages among tools within the AEE Tool Suite

Internal (AEE) and external (e.g., ACRP) efforts that could aid analysis and tool development

Populate flowchart with existing tools and databases 

Identify gaps that need to be met to enable analysis capability

Create timeline of tool and database development that overcomes identified gaps to deliver analysis capabilities as needed

AEDT - Continuing Projects to Improve Modeling

A11: Rapid Fleet-wide Environmental Assessment Capability

Complement AEDT with lower fidelity screening tool capability to examine large number of policy scenarios that could be quickly analyzed and reduced to a manageable set of scenarios for more focused, high fidelity analysis in the environmental tools suite.

A12: Aircraft Design and Performance Tool Connectivity with AEDT 

Extend compatibility of novel and existing aircraft design and performance assessment tools with AEDT to enable assessment of future scenarios using broad range of aircraft models

A23: Analytical Approach for Quantifying Noise from Advanced Operational Procedures

Developing analytical approach to address current noise modeling gaps such that it will be possible to capture changes in community noise due to the use of advanced operational procedures
