Identifying Viable Techniques for Modifying NextGen Flight Track Design to Reduce Community Noise Exposure and Annoyance In Reserve

This research would examine several examples where implementation of Metroplex or other procedures has resulted in widespread increased community complaints and would explore options for redesigning those flight tracks to reduce noise concentrations over noise sensitive areas while satisfying project design goals and constraints. Changes in aircraft noise exposure, fuel consumption, and air emissions would be quantified... more »

Airport Best Practices in Sustainability

By understanding what other airports are doing in the very wide subject area of sustainability, it may spur airports to try different means of conserving energy, recycling materials, or otherwise improving its sustainability practices. By looking not only at the practices, but the results, the challenges to implementation, and the costs of implementation, airports will be provided with guidance to improve their practices... more »

Aircraft flight procedures: successful implementation to minimize noise exposure

Flight procedures are a key element to predicting and minimizing noise impacts. Deviations from these procedures are causing unnecessary community noise exposure. Identifying deviation-related increases in noise and ways to minimize the deviations will help to reduce noise in communities in the vicinity of airports.

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 »

Airport Accident Analysis and Impacts to Safety Zones

Aviation accident data has limitations for establishing airport safety zones used to guide airport-vicinity land use decisions. Establishing uniform reporting criteria across responsible agencies will assist local jurisdictions to define safety zones and apply them to maintain airport viability.

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 »

Airside Planning, Design and operations: Electronic Resources Library In Reserve

The objectives of this research project are to:
• Create an electronic resources library – preferably a website. This searchable electronic library should provide an inventory of available publications including the abstracts and index of ACRP research documents and non-ACRP research documents related to airside planning, design and operations.
• Recommend a process for keeping the website up-to-date.
• Identify which... more »

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 »
