Minutes from Meeting

Presentation What’s New in AEE | Presenter Curtis Holsclaw

Discussion: In terms of personnel, Levent Ileri is the new CLEEN Program Manager. He comes 

from the FAA Next Generation Organization (ANG). Julie Marks is the acting Deputy Director 

of the International Office (API). As a result, Kevin Welsh is acting as the Division Manager for 

the Policy and Operations Division and Pat Moran is acting as the Senior International Advisor. 

We are looking to hire a new person for our Policy and Operations Division to help with market 

based measures.

In terms of budget outlook, we look good for FY14 but there are concerns in FY15 and FY16. 

Noise continues to be an issue with considerable congressional attention. Aircraft noise has 

always been a concern for our office. Helicopter noise is becoming an issue in certain areas. We 

see emerging concerns with noise from commercial space and UAVs.

We continue to develop a basket of measures to address climate change including the ICAO 

CAEP CO2 standard, market based measures. 

We continue to have close collaboration with EPA. We had a face-to-face scheduled but that was 

cancelled due to snow storm. 

In terms of rulemaking, we published Stage 3 helicopter noise standard. We have initiated efforts 

to promulgate ICAO Chapter 14 noise standards which will be known as the Stage 5 standard. 

Presentation CAEP & Global Market Based Measure (MBM) Update | Presenter

Lourdes Maurice

Discussion: We have a goal of getting to a decision for a CAEP CO2 standard in Feb 2016. We 

also hope to make progress on Particulate Matter. 

ICAO is also pursuing a global market based measure as a gap filler to meet CO2 goals. The US 

hosted a meeting in early March on this matter. The US is putting in considerable effort to 

support the development of this effort. The FAA will keep the subcommittee up to date on this 

work as we move forward. 
ICAO Counsel have created a strawman concept to examine MBM and to use it as the basis for 

discussion and debate within the Environmental Advisory Group (EAG). It is the beginning of 

the process and provides a way forward to 2016. This process is providing suggestions on 

offsetting schemes and how a global MBM could work. Two elements have been handed to 

CAEP for examination: Monitoring Reporting Verification (MRV) and Carbon Unit Quality. 

Presentation Plans for Future Summer Subcommittee Meetings | Presenter Dennis 

Filler

Discussion: The world is changing faster than the five year time frame that is currently built into 

the REDAC schedule of looking three years out (FY16+). This leads to several questions: 

- How can we make the FAA more proactive instead of reactive?

- How could we use the summer REDAC meeting to help us find the areas that are not 

currently being covered so we could influence matters? 

Dennis is interested in having 15% of the FAA RE&D budget be applied to near-term problems 

and not have it be ear-marked to individual BLIs. Dennis would like to use the REDAC 

subcommittees to provide advice for how this money could be spent. 

This is being prompted by the need to ensure FAA are funding items that are not currently being 

covered and doing it in the near term. For example, do we need to do more work on the 

following: 

- Commercial space. FAA allocates $1M for this right now. Is this sufficient? 

- UAV is not being covered adequately 

- Could additive manufacturing be used somehow to advance aviation 

- Use of fuel cells in general for propulsion 

Dennis is looking for discretionary R&D to cover things that we had not covered for our longterm planning. He is looking for more RE&D funds to cover this – he does not want to take this 

from existing RE&D funds. He is looking for input from the Summer REDAC meeting to 

identify areas that could be covered by these funds. 

There was discussion to leverage the fundamental research being conducted by other agencies 

(e.g., NASA) and to have the FAA work on developing an ability to conduct certification by 

analysis. A subcommittee member noted that this is exciting from a researcher’s perspective but 

it is very different from what this Subcommittee does. If input is needed for this from the 

Subcommittee, then a smaller group could form within the Subcommittee to help develop this. 

Juan Alonso is willing to lead this small group.

Presentation Previous REDAC Recommendations / Actions| Presenter Jim 

Hileman

Discussion: The subcommittee closed all recommendations from the Spring 2013 meeting. It 

closed all but one recommendation from the Summer 2013 meeting. Recommendation #6 

remains open. The FAA was asked to work with stakeholders on the development of its new fuel 

efficiency metric and to provide a briefing on the development of a fuel efficiency goal and 

metric at the Summer 2014 meeting.

Presentation Budget Update | Presenter Mike Gallivan

Discussion: Mike presented budget numbers and language from the FY14 budget including 

information on the $8M increase to environment and energy budget. He also presented the 

President’s budget request for FY15. The RE&D budget level falls in line with historical levels 

which have it as being between 1 and 2% of the total FAA budget. FAA are going to a new 

structure for funding F&E that is based on portfolio. As such, items were moved around to match 

the portfolios – this includes a budget line item relating to environment. Debt ceiling and 

sequestration are not issues for FY15 budget. Sequestration could be an issue for FY16 budget. 

FY16 budget will be submitted to OST in early June 2014 and OMB submission will occur in 

early Sept 2014. Scheduled data of FY16 budget presented to Congress in Feb 2015.

Current authorization goes through FY2015. FAA has started work on its proposed revision. 

JPDO work has been absorbed into ANG. Talks are ongoing to see how this will be fully worked 

out.

Presentation FY16 Program Proposal | Presenter Jim Hileman

Discussion: Jim gave an overview of the Environment and Energy Research Portfolio and the 

FY16 program proposal. The briefing noted reductions in funding which are anticipated in FY15 

and FY16. Jim also presented a multiple-year above target funding request with a $5M request 

for FY16 to support aircraft technology maturation via the CLEEN program and the 

advancement of alternative jet fuels. The briefing concluded with how AEE are prioritizing their 

research given coming cuts.

The Subcommittee expressed concerns about the large reductions in F&E funding and its 

impacts on AEE research on operations research and tool development. 

Page 3
The Subcommittee feels that AEE research programs are leveraging funds well – public-private 

partnerships are doing this very well – PARTNER, ASCENT, CLEEN are all terrific evidence of 

this. The Subcommittee is very supportive of how AEE have prioritized their research and the 

Subcommittee “strongly supports” the above target request.

Presentation Noise Research Update | Presenter Rebecca Cointin

Discussion: Becky updated the noise research roadmap and new work for FY14 in AEE and 

ACRP. Research roadmap was very useful to moving projects forward.

A member of the subcommittee expressed concern that aviation research being done by ACRP

could be better done by AEE. Other committee members that represent airlines noted that it is 

better to have the work done by ACRP instead of not being done at all as AEE does not have 

sufficient budget to do everything.

There was discussion around research on the health impacts of noise and the FAA noted they are 

directing people to the NoiseQuest page to educate people who are expressing concern about 

aviation noise.

A Subcommittee member commented that Becky is doing very good work to develop the 

roadmap and conduct survey. The FAA will reach out to ACI and selected airports after it gets 

through review with OMB/BTS on the survey. That should happen in late spring/early summer

Presentation Emissions Research Update | Presenter Ralph Iovinelli

Discussion: Ralph presented on several key efforts in AEE. 

He started with a discussion on the development of an international standard for measuring 

emissions of non-volatile particulate matter. Ralph said that ICAO CAEP is evaluating what can 

be accomplished to create an international non-volatile particulate matter standard by Feb 2016 

(CAEP/10 meeting) and by Feb 2019 (CAEP/11 meeting). 

He covered the air quality research within FAA. The subcommittee was complimentary of the 

efforts at UNC and MIT to place aviation in context of other sectors. 

He discussed ongoing climate work. He showed an APMT-Impacts Climate result that 

demonstrates how ACCRI research has reduced uncertainties in terms of the climate impact from 

aviation. He presented ongoing work to estimate regional impacts of climate change due to 

aviation operations. There was a comment that it is important to reduce uncertainties, but FAA 

also needs to understand that there is diminishing returns in reducing uncertainties and that some 

uncertainties may not be reducible as they extend beyond aviation.

He presented ongoing work to examine the surface air quality impacts from cruise emissions. 

The research effort is using 6 different models with consistent assumptions across the board to 

better understand the science involved.

Presentation NextGen EMS ‐ Update on Stakeholder Collaboration Program | 

Presenter Don Scata

Discussion: Don presented on the Stakeholder Collaboration Program within the NextGen EMS 

effort. 

One of the subcommittee members noted that the FAA should be very careful in how they refer 

to this program as there is no EMS for all of aviation. We can call our part of this an EMS but we 

should not imply that there is an overarching EMS for all of aviation. 

Based on interest from earlier in the day, Don presented information on the NextGen 

Environmental Collaboration website. These are backup slides in his slide deck. 

Presentation Tools Update | Presenter Mohan Gupta

Discussion: Mohan walked through the work that we are doing to develop analysis tools. He 

went into detail on AEDT and how we are leveraging the PDARS data stream to do our work. 

He finished with a slide outlining our FY14 activities. 

There was some discussion about AEDT2a and the release of Service Pack 2 which fixed errors 

that could have impacted the evaluation of planned OAPM analyses

(https://www.faa.gov/air_traffic/flight_info/aeronav/procedures/oapm/). Jim H noted that the 

work to create Service Pack 2 could result in a delay of the AEDT2b release but FAA are doing 

our best to avoid this. 

One of the subcommittee members asked about similar efforts in Europe on tool development. 

Mohan mentioned the TeamPlay effort. 

Presentation Goals Analysis Update | Presenter Chris Dorbian

Discussion: Chris presented progress in estimating future CO2 emissions, energy efficiency, and 

noise. He gave a refresher on what was done previously with CO2 as the example. He walked 

through the plans for the Spring 2014 re-run and the longer term plan for work. 

There was discussion about how the work can inform technology development as it is showing a 

gap between the FAA and industry goals for aviation CO2 emissions. There was a desire from 

one member to see historical data as well as the future trends. Another member wanted to ensure 

that the work was able to identify the technology gaps that could fill the CO2 gap. While there is 

considerable interest in the work, the only new action item is to add historical perspective to the 

data being presented.

Presentation CO2 Analysis Update | Presenter Laszlo Windhoffer 

Discussion: Laszlo gave an update of the work that has been ongoing to support the 

development of the ICAO CAEP CO2 standard. The Subcommittee was very complimentary of 

these efforts.

Presentation Operations Research Update | Presenter Chris Dorbian

Discussion: Chris presented the operations research roadmap with a focus on the cruise altitude 

and speed optimization analysis, delayed deceleration approach analysis, and N collaborative 

surface control efforts including plans for the coming New York demonstration. 

During the discussions, there was a question about what is happening at Denver in terms of 

operations and how that fits into the DDA concept. We later determined that Denver is 

implementing RNP. There was also discussion surrounding the DDA Human in the Loop (HITL) 

experiments with the Subcommittee being supportive of the work. 

The Subcommittee members were very complementary of the CASO, DDA, N-control efforts 

and would like to see this work continue as it shows good promise. 

A Subcommittee member requested that the Operations Research Roadmap cover future years. 

The Subcommittee thinks we are getting great results from our Operations Research and they 

need to continue. There was discussion of finding a way to use RE&D funds to complement 

F&E to ensure this work continues. There was further discussion on the potential gap between 

developing new operations and their implementation by the FAA. 

One of the Subcommittee members would like to see how the operations pieces fit together. This 

is something that could be worked into the Goals Analysis effort. 

Presentation Aircraft Tech – CLEEN Update and CLEEN II Status | Presenter

Levent Ileri

Discussion – Levent presented update of progress in maturing technologies within the CLEEN 

program. There was agreement on the importance of continued collaboration between NASA and 

CLEEN. One of the Subcommittee members requested a roadmap of the CLEEN program with 

expected EIS.

As CLEEN I comes to a close, there will be a question about the benefit of CLEEN relative to 

the expenses that were incurred. Further, what was accomplished that would not have happened 

if there was no CLEEN funding. A Subcommittee member recommended that we develop these 

information. 

There was agreement that FAA needs to communicate the positive results from CLEEN and that 

industry needs to help with this. As an example, there was heavy coverage for the 

ecoDemonstrator work including the cover of Aviation Week. 

Jay noted that ERA will come to an end in December 2015

what has been accomplished with the funds that have 

been invested in CLEEN, including anticipated EIS 

dates.

Presentation NASA Update | Presenter Jay Dryer

Discussion: Jay presented on NASA’s recent restructuring of their aeronautics program and how 

they developed their overarching strategy. The result is a program with four programs: Airspace 

Operations and Safety Program, Advanced Air Vehicles Program, Integrated Aviation Systems 

Research, and Transformative Aeronautics Concepts Program. The Subcommittee members were 

complimentary of the presentation and the restructure. Jay will be heading up the Advanced Air 

Vehicles Program and John C will be heading up the Airspace Operations and Safety Program. 

The Subcommittee had a discussion about how NASA and FAA work collaboratively on 

technology development. As has been the case since the outset of CLEEN, NASA will focus on 

lower TRL technology maturation that is not industry specific and FAA will focus on higher 

TRL with an emphasis on technology maturation with transition to industry. All were in

agreement that there is great collaboration between FAA and NASA.

Presentation Alt Fuels Update | Presenter Nate Brown

Discussion: Nate presented an overview of the alternative jet fuels research that is being 

conducted by FAA. He walked through efforts on testing and emissions measurements; analysis 

of economic costs of production and environmental impacts of fuel use; and coordination 

including CAAFI and the Farm to Fly 2 effort. He finished with a slide that outlines FY14 

efforts.

There was a question about how FAA are structuring their efforts to support testing in the near 

term to support the existing C/Q process and to improve the C/Q process with the AFRL along 

the lines of the Rules and Tools program. The Subcommittee was very appreciative of the FAA 

carrying on the AFRL Rules and Tools program. They are also very happy with the overall 

efforts of the FAA on alternative jet fuels.

Action items Person responsible Deadline

Provide a briefing during August meeting on testing to 

support existing C/Q process. Presentation should 

include high level description of the coordination that is 

taking place on this front.

Presentation DoE Update | Presenter Zia Haq

Discussion: Zia presented DOE efforts on alternative jet fuels. This included their integrated 

biorefinery projects and their support of the Defense Production Act with US Navy and USDA.

There was discussion about how the three agencies are working together to support fuel 

production via DPA. Zia finished with some of the outcomes of the recent Gas-Biomass to 

Liquids workshop.

Presentation USDA - Alt Jet Fuels Efforts | Presenter Harry Baumes

Discussion: Harry presented on USDA efforts on alternative jet fuels. He discussed Title IX of 

the Agricultural Act of 2014 which covers energy. He followed with information on USDA 

research efforts including the NIFA AFRI CAP efforts at Washington State and U. Washington 

(among others). He also discussed collaborative efforts including those with EPA, Farm-to-Fleet, 

the joint USDA/DOE Biomass Research and Development Initiative (BRDI) which has had its 

funding reduced considerably, Farm-to-Fly 2, CAAFI, MASBI, etc. He noted that these efforts 

are a national priority. He went into more detail on Farm-to-Fly 2 and CAAFI and how USDA 

are involved with the CAAFI state initiatives. Harry offered to share more information on their 

research efforts if anyone on the Subcommittee wants it.

Presentation EPA | Presenter Sharyn Lie

Discussion: Sharyn is the Director of the Climate Economics and Modeling Center within the 

Office of Transportation and Air Quality within EPA. Her office is in charge of the life cycle 

greenhouse gas assessment for the Renewable Fuel Standard (RFS2) program. Renewable jet 

fuels can be used to generate RINs but jet fuel users are not obligated parties to purchase RINs. 

There is a petition process for parties to get their fuels included within the RFS2 program. She 

thinks that jet fuel represents a great option for helping EPA meet its goals. There have been 

changes to the petition process to try to make it better and these have been posted onto the 

website.

Sharyn is very interested in knowing which fuels and feedstocks are approaching ASTM 

approval so that EPA is prepared. 

Action items Person responsible Deadline

Share ASTM approval progress with Sharyn’s office at 

EPA.

Presentation NAJFS | Presenter Mohan Gupta

Discussion: Mohan presented progress in the development of a national alternative jet fuel R&D 

strategy that is providing the coordinated R&D plan for the U.S. Federal Government. A 

Subcommittee member noted a desire to ensure that this document is followed by the agencies 

who are involved in its creation.
