HMMH is highly regarded for our aviation consulting experience, including controversial vertical lift (helicopter, heliport, and helipad) projects and new entrant aircraft, such as the Lockheed Martin F-35 Lightning II military fighter. Our experience in advanced air mobility (AAM) has ranged from developing noise computer prediction models to conducting noise measurements to presenting the results to the affected communities to developing programs to address community concerns.
As part of this work, we examine the potential community annoyance related to the introduction of operations at proposed heliports/helipads in urban, suburban, and rural areas and the proposed replacement of fighter aircraft at joint-use airports. This can involve the development of preferred flight corridors and establishment of minimum operating altitudes as elements of comprehensive programs at airports/hospitals, either from civilian operators or joint-use National Guard units.
Our vertical lift aviation expertise supports our clients in the implementation of urban air mobility (UAM) utilizing AAM, such as electric vertical take-off and landing (eVTOL) vehicles. UAM is functioning at many airports and hospitals using helicopters. We expect a relatively swift transition from helicopters to eVTOL vehicles over the next several years. With eVTOL vehicles expected to be much quieter, possibly as quiet as existing ambient acoustic environments in urban areas, this transition will expand UAM across the globe, beyond urban areas, and into suburban and even rural areas.
We have a successful track record of airport/community noise forums leading to amicable solutions for the varied stakeholders and public acceptance. Our knowledge of airports, airspace, aircraft, and community perspectives has proven essential in these efforts. Our focus for the forums is to solve perceived noise problems through working with all stakeholders, including the airport, communities, aircraft operators, local airport traffic control tower, and regional FAA administrators.
We typically begin such forums with the public adamantly opposed to a recent change and believing HMMH is on the side of the airport/FAA. We are then thanked by the same critical community members for our diligent work and finding implementable solutions – we know it is all about public acceptance. The same will be true for the successful implementation of AAM.
Additionally, HMMH is a transportation environmental consulting firm and has experience with all modes of transportation. AAM is the next frontier of transportation and will likely rely on all of the existing modes of transportation for its successful implementation. Our experience in transportation and models used throughout the transportation industry will be instrumental in the planning of AAM implementation.
HMMH is a deeply engaged member of several organizations focused on AAM, including NASA’s Urban Air Mobility Noise Working Group, Community Air Mobility Initiative (CAMI), and Canadian Advanced Air Mobility Consortium (CAAM). We are proud to have contributed to the recently released Technical Paper on “Urban Air Mobility Noise: Current Practice, Gaps, and Recommendations” from NASA’s Urban Air Mobility Noise Working Group (UNWG).
