Commercial Space Transportation Noise Model Validation

Accurate predictions of the noise environment in communities surrounding airports and spaceports from launch and reentry vehicle operations require models that have been validated over a range of vehicle types, operations, and atmospheric conditions. Research is needed to validate the commercial space operations noise models developed under ACRP 02-66 using the community noise measurement database collected under ACRP... more »

Facilitating a Better Understanding of Water Quality of Airside Stormwater Runoff at Airports

In accordance with the Clean Water Act, airports must responsibly manage stormwater runoff through a combination of industrial stormwater permitting, MS4 permitting, and state/local post-construction stormwater requirements for development. Permitting requirements for airports can vary widely across the nation, with some airports also subject to municipal stormwater fees. These fees may be reduced via credits for effective... more »

Understanding Airport Noise & Air Quality Baselines and Relationship to Operations

The COVID-19 pandemic has resulted in a drastic reduction (in some cases over 95%) in air traffic operations at airports around the country. The only other time such extreme conditions occurred was after 9/11 (with three days of a total ground stop). The current situation presents an opportunity to collect significantly more data from a longer time period for both noise and air emissions to understand baselines, and the... more »

Urban Air Mobility Noise Modeling

Community acceptance of the rapidly emerging Urban Air Mobility (UAM) market will be strongly driven by public noise concerns; however, no regulatory tool exists to evaluate potential environmental noise impacts. Whereas conventional helicopters have one or two rotors, UAM vehicles may have large numbers of rotors for different functions that operate at variable speeds. These differences necessitate the development of... more »

Financial Impacts of Climate Change

Airports need to build resilience and understand the potential long term impacts of climate change. However, they bump up against costs of implementing projects with resilience elements because there is little aviation specific data regarding the return of investment of such projects and the overall financial risks of climate change. Additionally, as insurance and the availability to retain loans gets more in line with... more »

Vegetation Height and Impacts on Deterring Small Birds on Airports

Vegetation and grass height is suggested to be between 7-14 inches on airports to deter small bird species; this concept has been tested in the past, with mixed results. I suggest a study should be conducted building on the previous publications keeping in mind new technologies and different grass management strategies to determine if current best management strategies are sufficient or may need to be updated.
