Effective practices for monitoring and managing tree growth off the airport. In Reserve

Conduct research into cost effective strategies for periodic monitoring of airspace surfaces such as TERPS 20:1 surfaces to ensure they remain clear of obstructions. Particularly at smaller rural airports that may not have staff, zoning, or significant infrastructure that would otherwise make these issues easier to manage.

In-Flight Aircraft Emissions Tracer Study

The emissions dispersion model used by airports for regulatory purposes does not account for aircraft-specific exhaust emissions transport and may be under- or over-estimating ground-level concentrations. Tracer studies for aircraft do not exist as they do for vehicles and are needed to evaluate newly developed dispersion models designed to better estimate the transport of aircraft exhaust emissions during low-altitude... more »

Legal Aspects of Airport Programs

Preparing Airports for Legal Considerations with Innovative and Emerging Aviation Technologies

The legal, policy, and regulatory environment may present challenges for certifying and authorizing some technologies due to novel features and combinations of features that could be found in novel aircraft designs. While this is not an exhaustive list, some of these could include distributed electric propulsion/tilt-wing propulsion, vertical take-off and land, autonomy hardware and software, optionally piloted configurations,... more »

Synthesis of Airport Related Ultrafine Particle (UFP) Emissions Research

In recent years, there has been an a growing concern regarding emissions of aviation related ultrafine particles (UFPs). This effort would consolidate relevant research regarding aviation and UFP emissions in order to provide useful insight to airports, stakeholders, and the public.

Update to Report 147: Climate Change Adaptation Planning, Risk Assessments for Airports In Reserve

Update to Report 147. The climate data in the ACROS tool is outdated and requires update. The original publication is based on data from prior to 2013; weather and climate data has been continually updated since the original publication was released (which affects the likelihood and severity of various risks in the assessment tool). Additionally, there are more recent examples of airport case studies and best practices.... more »

Update to Report 11: Preparing Airport Greenhouse Gas Emissions Inventories In Reserve

The original guidebook provides essential information to airports developing greenhouse gas (GHG) emissions inventories. However there have been a number of developments in methodology and resources available since original publication and an update is needed for this publication to remain relevant/useful. This research update idea was developed as part of project ACRP 11-02/39, Environmental Products Update and is one... more »

Optimizing Airfield Snow Removal

"The objective of this project is to research best practices focused on managing the resources at airports to optimize the number of runways and taxiways that can be kept open during winter storms. The guidelines should include using process optimization to reduce variation caused by unpredictable weather events and computer simulation analyses to optimize the number of equipment needed, resources required, and optimize... more »

Subsurface Drainage System Benefits in Airport Pavement Performance

This research would summarize the best of practices through survey of airports and consultants; evaluate the effectiveness of subsurface drainage configurations by investigating field performance of airport pavements with and without drainage features; quantify the cost and benefits of including subsurface drainage by comparing any potential extension in service-life with increased construction and maintenance costs;... more »

Methods for Evaluating Airfield Pavement Deicer Contributions to Airport Stormwater Quality In Reserve

The objective of this research is to develop guidance for airports to quantitatively identify the contributions of airfield pavement deicers to environmentally relevant characteristics of stormwater discharges, such as COD and BOD.

Requested Allocation (For ACRP Use Only) $350,000

Electric Aircraft on the Horizon - Planning handbook for Airports In Reserve

Generate informed guidance for airports to plan for electric aircraft adoption. Electric aircraft could begin operating from airports within 3+ years. The aviation industry lacks a method to distinguish between marketing hype and realistic projections. A new ACRP report could provide help airports understand which sites are best suited for the viable technology associated with electric powered aircraft. Airports would... more »

Airport Travelers' Emotions related to Improving Airport Customer Experiences

Most U.S. airports do not have a complete understanding of the range of emotions their travelers experience at the airport. More research needs to be conducted to identify the sentiments expressed by passengers at different journey points and the root causes for why they feel the way they do. Once the root cause is identified, airports then must consider resolving any issues related to a negative emotion experience by... more »
