GREGG: As the aviation sector evolved in the 1990s and 2000s, FAA realized

there was a need for a different capability--a capability to evaluate

aviation environmental interdependencies, to be able to look at tradeoffs across

the environmental domain. JONATHAN: In the past, there had been five separate tools to figure out the

environmental consequences of noise, emissions, and fuel burn on various scales.

LOURDES: But the reality is none of these effects are standalone; they're are all interrelated.

GREGG: AEDT, or the Aviation Environmental Design Tool, is the first software tool of its type.

LOURDES: AEDT is a Federal Aviation Administration NextGen software tool that we use to analyze the effects

OF environmental impacts. CHRISTOPHER: It's a single model capable of predicting fuel burn, noise

and emissions for aviation operations and it's scalable all the way from a

single runway all the way up to a global analysis. JONATHAN: From the beginning AEDT was a

collaborative process. It started with stakeholders getting together from a wide

range of expertise to understand and identify requirements. LOURDES: The FAA has relied

heavily on the Volpe Transportation Center to do a lot of the integration and development.

JONATHAN: AEDT is designed with the user in mind. It's arranged to help

efficiently answer questions about environmental consequences of aviation.

The consequences are evaluated through metrics in a familiar interface.

CHRISTOPHER: Once you're in the model, you put all your assumptions in, tweak various scenarios

depending on the types of things

specific output you're looking to get, then you run the tool and look at the results.

JONATHAN: You're able to look at information in the geospatial (or a map-based format),

and you're also look at information in a tabular format.

LOURDES: For example, you might look at number of people exposed to noise, or you might look at tons of a certain emission.

CHRISTOPHER: Throughout the development of AEDT, it's already been used for a number of analyses. LOURDES: We laid

out that releases in a phased approach and we actually released the global capability first.

That has been used within the International Civil Aviation

Organization to inform decisions on two standards. GREGG: These assessments--they have a multi-billion

dollar impact on the aviation enterprise. JONATHAN: Going forward,

AEDT will continue to inform policymakers and decision-makers regarding

environmental consequences. CHRISTOPHER: As the world evolves, other tools and other data

sources evolve, and the intention is to keep AEDT at the forefront and state-of-the-art.

JONATHAN: We're going to continue to listen to stakeholders to understand what's most

important to them in terms of ongoing improvements in the science and the data beneath AEDT.

LOURDES: To me, if I were to sum it up, it's the best example of transition from

research to use that I have seen. JONATHAN: AEDT is a significant accomplishment. It took a team

of experts working together, establishing and working against a diverse set of requirements.

GREGG: I'm very proud that we're seeing used and having such an impact on the industry, not only

nationally, but also internationally.
