HMMH Fall Tour 2015: On the Road Again

Friday, November 13th, 2015

by Mary Ellen Eagan

I’ve been on the road this fall at conferences – a whole lot of air miles, too many hotels, chicken lunches, and name tags (someday these will be designed for wearing on something other than a suit jacket lapel), but lots of great discussions, more than a few cocktails with good friends, and many laughs along the way. Some common themes emerged; here’s a recap of my highlights/takeaways:


Air Transport Action Group (ATAG) Global Sustainability Aviation Summit (Geneva)

At ATAG, ACI and Canso jointly released a document entitled Managing the Impacts of Aviation Noise, which provides a concise summary of airport noise issues, strategies for mitigation, and an extensive series of case studies. On community engagement, the report recommends following guidance issued in Eurocontrol’s Collaborative Environmental Management (CEM). One key difference between the European approach and ours is that the airport is at the center of the discussion. I am pleased to have contributed to the document.



ACI World Environment Standing Committee (Geneva)

Australia has seen good success in improving relations by having a very engaged and completely independent Aircraft Noise Ombudsman, who serves as a neutral party facilitating discussion of noise abatement alternatives, and educating the public using language that is not jargon. The Australians also provide guidance to airports (and others) on how to properly address complaints. And Canada recently released an Airspace Change Communications and Consultation Protocol for engaging communities and other stakeholders in discussion of proposed airspace changes. It, too, puts airports at the center of the discussion.



ACI-NA Annual Conference and Environmental Affairs Seminar (Long Beach)

My presentation at ACI focused on the concept of social license to operate (SLO), which originated in the mining industry. The premise of SLO is straightforward: owners of businesses and other enterprises that generate negative externalities must secure permission from stakeholders in order to grow – sometimes even to operate. And that permission is earned (not simply granted), by engaging stakeholders in a relationship that evolves from acceptance to trust. As shown in the illustration below from Social License institute, deteriorating levels of trust can lead to active political engagement and protest, as we’ve recently seen with the No Fly movement.


EFCG CEO Conference (New York)

This annual gathering of almost 300 CEO’s of firms in the A&E industry provides great perspective on the state of the industry, trends in financial results and other industry benchmarks, and an opportunity for firm leaders to share experiences on all kinds of issues facing our industry, including talent shortages, ownership transition models, and implications of new business models, technologies, and regulations. My favorite moment of the conference was my realization – during a fancy dinner at the Harvard Club – that the nine other CEO’s I was dining with were more interested in talking about their pets than their businesses. CEOs are people, too.



AAAE Basics of Airport Law Conference (Washington)

John Putnam (KKR) and I provided a session on emerging noise issues. Much of that discussion focused on PBN issues, the challenges posed by NEPA requirements in evaluating PBN procedures (not only at individual airports, but on a metroplex scale), and implications of FAA Reauthorization on airport noise issues.



ACC Annual Conference (Newport Beach)

There was much discussion at the Annual Meeting on the need to engage politically in conversations about airport development. ACC President TJ Schultz’s knowledge and insight into FAA funding and other political realities provides ACC member firms (especially small ones like HMMH) with context for making strategic decisions. I am honored to have been elected incoming Secretary/Treasurer for 2016, and look forward to serving on the ACC Executive Board with Don Bergin and Roddy Boggus.



ACI-NA Marketing and Communications Conference (Nashville)

ACI-NA’s Marketing and Communications conference held a session on airport noise. This is very exciting to me because the longer I’m in this business, the more I’m convinced that a good deal of airport noise issues can be addressed by better communication. I’ve come to this for several reasons: (1) first, we know that only about 30% of people’s annoyance to aircraft noise can be attributed to the noise level – that leaves a lot of opportunity for using “non-acoustic” measures to address noise issues; (2) after 30+ years in this industry, I am positive that people don’t suddenly start complaining about aircraft noise unless there has been some change in their environment or their life: a new runway, a new procedure, a new home, a new job (and increasingly, retirement). Working with stakeholders to understand the reasons for those changes often goes a long way toward resolving annoyance – sometimes it can be addressed, but even when it can’t, folks generally are satisfied that they have been listened to and validated.

Bottom line: sometimes the best consulting one can offer is to listen.


Looking forward to a brief respite (though I’m presenting remotely to the Aircraft Noise Non-Acoustic Group (ANNA) in The UK on Thanksgiving – hopefully not messing up the turkey too badly in the process). Then back on the road again in December to wrap up the year at ACC/BAG Global Business Summit (London) and ACI/ACC Planning and NEPA Workshop (Washington).



ERAU Is Pushing the Envelope Yet Again!

Friday, May 16th, 2014

by Diana Wasiuk

Graduates of my alma mater, Embry-Riddle Aeronautical University (ERAU), have a reputation for ‘pushing the envelope’ in more than one way… The Small Aircraft Transportation System (SATS) was one of those forward thinking ideas that only a bunch of aviation nuts could come up with and commit to with boundless enthusiasm. And boy did we ever!  Here is an article on another example of ERAU pushing for innovation: developing electric propulsion systems to reduce noise and emissions:

TRB e-circular “Critical Issues in Aviation and the Environment” published

Friday, April 18th, 2014

By Mary Ellen Eagan

TRB recently published Circular E-C184: “Critical Issues in Aviation and the Environment.” The following summarizes the content of the e-circular.

“Critical Issues in Aviation and the Environment 2014” consists of twelve individually authored sections, representing the authoring experts’ opinions on issues that address the major environmental components affected by aviation activities, sustainable solutions that have evolved and continue to be developed to minimize environmental impacts, and the key processes that link aviation and the environment.

Readers of prior e-circulars in this series may notice that we no longer include a stand-alone section on “sustainability”.  This is because the Committee believes that sustainability is a cross-cutting issue that affects all topics in the environment – it is a way of operating, not an “issue”.  We have added several new topics to this volume:

  1. Natural resource management:  Airports are challenged to address natural resource management issues related to wildlife hazards, natural resource revenue generation (e.g., timber, minerals, energy), and water conservation.
  2. Renewable energy:  this section addresses major issues airports should consider when identifying and developing renewable energy alternatives.
  3. Public Health:  an emerging issue that several airports are facing is the need to develop health impact assessments and health risk assessments to respond to community concerns regarding the impact of airports on communities.

The individually authored sections of this e-circular represent the viewpoints of the attributed authors.  Members and friends of the TRB Environmental Impacts of Aviation Committee have also reviewed and contributed comments to these sections.

Many thanks go to the authors (listed below, by paper):

HMMH Throwback Thursday (TBT): Field Trips in the Pre-internet Age

Thursday, March 27th, 2014

by Mary Ellen Eagan

My first data collection (“field”) trip was in the spring of 1985.  We were supporting litigation (at an unnamed airport), and needed to know how flight schedules had changed over time (in order to prepare comparison DNL contours).  I was given the daunting task of going to Eastern Airlines Headquarters in Miami (at the time, Eastern was the only known source of historic flight schedule information) to copy pages from the Official Airline Guide (OAG), which looked something like this.

The data needed to be re-typed (into Lotus spreadsheets), sorted, etc. – just to determine average daily flights on any given route.

That’s how the glamor began.

From Miami, I flew to Portland, Maine for my first trip involving instruments (alas, I’ve been unable to locate a photograph of a Digital Acoustics 607 noise monitor).  Nick Miller and I were measuring noise levels near Naval Air Station Brunswick, home of Pat Wing 5 and the P-3 Orion Naval Patrol.

What I remember most about that trip – and tell my girls every time we drive past the old base (the base is gone – it’s now Brunswick Executive Airport, but the Fat Boy Drive-in is still going strong!) is that I was so engrossed in managing the noise monitor that I actually screamed the first time an aircraft flew overhead.  In my defense, that plane (a P-3) was on short final and probably at 100’ altitude (I know, because I got to figure that out later) and very quiet.  It was my first experience with ‘startle’.  What I also remember is Nick’s equanimity in the situation, while inside he must have been wondering just how long my career at HMMH would last.

There are so many differences between then and now, but the thing I miss most is the opportunity to get to know colleagues on a personal level.  In those pre-Internet days, once the sun went down, we were done working for the day – no email, no work in the hotel room, no cell phones even to call home.  It left lots of time for exploring neighborhoods, which could sometime be a challenge near remote Naval Air Stations – but who doesn’t like a challenge?  For example, in the photo below, Bob Miller is seen defending me from an unseen rattlesnake near Midland (TX).  We may be way more efficient these days, but are we still having fun?

Throwback Thursday (TBT): My First Noise Contours

Thursday, March 20th, 2014

by Mary Ellen Eagan

At the risk of mixing social media platforms (and incurring an eye roll from my teenage daughter), I’d like to announce a new blog series at HMMH:  Throwback Thursdays.

This idea was sparked as a result of the recent renovation of our Burlington headquarters, and the desire to preserve this collage that was prepared for the occasion of HMMH’s 10th Anniversary in 1991: 

HMMH-the early years1981-91

HMMH-the early years 1981-91

Our team has invested significant time scanning each of the photos in the collage, and my hope is that we can find something interesting to say about most of them (well, there are some NSFW things that won’t be shared).

My First Noise Contours

I thought I’d start off with a photo of my first noise contours.  As the date indicates, it was November 1984 (yes, I am that old); I was fresh from Cornell and a summer Internship with the Massport Planning Department; still wearing Birkenstocks and going to Grateful Dead shows (yes, I am that old).  Back in the day, this is what noise contour development looked like:

  • Operational Inputs were developed by typing ATC flight progress strips (see below) into a Lotus 1-2-3 spreadsheet on the company’s only computer – a Xerox (which looked something like this): 



  • Flight tracks were developed in one of two ways:  (a) interviewing the Control Tower manager, who would describe nominal controller instructions to pilots (e.g., Climb to 1000’, then turn on course”), or (2) someone (guess who?) would sit in front of a radar scope marking radar return dots on a piece of acetate – literally, dot-to-dot flight tracks.  These days, I just smile at folks who get worked up for only getting a 99% radar track sample to analyze.

  • Then the real fun began!  We typed the INM “input deck” (I’m a version 2.7 girl – we old-timers mark our age by first model used) into the computer (my colleagues will tell you about their experiences with punch cards, and submitted it to Control Data Corporation (CDC) over a dial-up modem for processing.  Each run cost several hundred dollars – we did a lot of QC before submitting!   Assuming all went well, we then got to DRIVE to Waltham (20 minutes without traffic) to talk to Manny and get the output – a green and white computer printout and (hopefully) a large plot with contours!
