ACRP IdeaHub Ideas

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 models developed under ACRP 02-66 using the community noise measurement database collected under ACRP 02 81.... more »

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 »

Conduct research on airport noise and emissions regulations,

requirements, programs in place at U.S. airports, including the impetus

for each, legal authority and impact.

Conduct research to update the state-of-the-science regarding the feasibility of reducing or eliminating noise in communities from aircraft departures, specifically behind the start of takeoff roll, with active noise reduction technology.

Produce a guidebook to provide a thorough overview of the emerging commercial space market and its implications for air traffic and airports. The research should include launch and reentry operations and cover emerging markets such as commercial crew operations to the International Space Station, space tourism, and fast point-to-point travel. The guidebook should address integrating flight operations with existing air... more »

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 »

The research will characterize the changes in community noise impacts due to the implementation of RNP procedures. It will provide a solid picture of the character and scope of the problem through case studies and noise modeling. Possible mitigation strategies will be explored detailing the advantages and disadvantages of each approach supported by parametric noise analyses.

The objective of this research effort is to develop written documentation on best available methods to model community noise generated from helicopter and tiltrotor operations. The document should address integrated and simulation modeling techniques, and methods for collecting and analyzing noise source data, and outline noise source development protocols. The language and format of the document shall be suitable for... more »

Determine if airport operations can be accurately counted using ADS-B data.

Synthesis of case studies showcasing what has worked well and what has not, to give examples of alignment between airport operators and land use jurisdictions. States might take different approaches from each other, and understanding these differences could be valuable.

Practical, usable, efficient, and fair methods for clarifying use of operational airspace near to the ground

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 »

The main objectives of this idea are providing the U.S. airport industry and their stakeholders (airlines, ATO, ground handling service providers, etc.) with the following: - Overview of the green taxiing solutions and their typical concepts of operations, - Impact of these systems on airport operations, planning and design. The research project includes producing or collecting: - An inventory of the existing and prospective... more »

Research is needed to help airports  better define the extent of the problem  better define the potential direct impacts of restricted scheduling windows  identify unintended consequences at both originating and destination airports from restricted scheduling windows on intercontinental routes  propose alternative noise mitigation strategies to achieve similar or better outcomes for communities in the vicinity of... more »

Urban Air Mobility (UAM) is a safe and efficient system for air passenger and cargo transportation within an urban area, inclusive of small package delivery and other urban Unmanned Aerial Systems (UAS) services, which supports a mix of onboard/ground-piloted and increasingly autonomous operations. In recent years, UAM has developed rapidly due to advances in technology and with pilot projects underway in Dubai and planned... more »
