The TRB Airport Cooperative Research Program's ACRP Web-Only Document 42: Toolkits and Resource Library for Airports and Unmanned Aircraft Systems provides supplemental material to Volumes 1 , 2 , and 3 of ACRP Research Report 212: Airports and Unmanned Aircraft Systems .

TRB's Airport Cooperative Research Program (ACRP) has provided more than $169 million in funding for 690 research projects since its inception in 2005. In those 20 years, publications and products have undoubtedly gone out-of-date. In FY2021, the ACRP Oversight Committee, along with ACRP staff, recognized the need to review past products and make updates where appropriate. ACRP Web-Only Document 5...

An important operational characteristic of an airport is the length of its longest runway. The longest runway determines the types of aircraft that can use the airport and dictates the operational limitations at the airport. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 54: Development of a Small Aircraft Runway Length Analysis Tool provides a user-friendly computer tool to...

Airport economic impact studies may accurately measure the activity that occurs on airport properties or is tied directly to airport operations (such as off-site parking and hotels that accommodate airline crew who overnight in a location), but they do not capture how air service supports business and employment throughout the region. The TRB Airport Cooperative Research Program's ACRP Web-Only Do...

Command-level decision making is a critical factor in successfully managing and mitigating critical incidents. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 52: Command-Level Decision Making for Transportation Emergency Managers is a document done in collaboration with TRB's National Cooperative Highway Research Program (NCHRP) and Transit Cooperative Research Program (ACRP...

Federal Aviation Administration (FAA) regulations require the licensing of spaceports and launch vehicles, which includes the assessment of environmental impacts. The TRB Airport Cooperative Research Program’s ACRP Web-Only Document 51: Commercial Space Vehicle Emissions Modeling presents a user-friendly tool for practitioners to estimate the emissions associated with commercial space vehicle acti...

With the airport industry's introduction and early adoption of safety management systems (SMS), safety processes are taking on a more proactive way of doing the business while continuously improving safety. This shift in approach will drive safety research in the near and long-term future. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 50: Research Roadmap on Safety Issues r...

The administration and human resources functions within an airport can experience great challenges as airports grow, diversify, experience changing priorities, bring in new technologies, or change in other ways. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 49: Research Roadmap on Airport Administration & Human Resource Issues recommends priorities and timing, sets a re...

Knowing where people are at different times of the day potentially enables the design of airspace routes that minimize the environmental impact to a shifting population on the ground. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 48: Evaluating the Use of Spatially Precise Diurnal Population Data in Aviation Noise Studies examines the potential role of spatiotemporal popula...

As the frequency of commercial space operations and number of licensed launch sites in the United States continue to grow rapidly, accurately assessing the impacts of propulsion noise and sonic booms on surrounding communities will become even more critical. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 47: Commercial Space Operations Noise and Sonic Boom Measurements devel...

When exposed to certain foods or fluids, recyclables arriving on international flights are required to be quarantined due to potential contaminants. As a result, almost every country worldwide prescribes sterilization, incineration, or other disposal methods for these contaminated recyclables. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 46: Recovering International Recycl...

Airports must maintain a safe and efficient facility while considering environmental impacts. Though traditional environmental challenges such as noise and water quality remain, several new themes are emerging, including energy management, sustainability, resiliency, and wildlife management. Airports will need guidelines and practices to help them address these pressing issues, and the first step ...

Barriers, berms, buildings, and natural terrain may affect the propagation of aircraft noise by shielding or reflecting sound energy. If terrain and manmade structures obstruct the line‐of‐sight between the source and the receiver, then sound energy will be attenuated at the receiver. This attenuation increases with the terrain and structures’ size and proximity to either the source or the receive...

One of the most challenging environmental issues facing the aviation industry today is the impact of jet fuel emissions on the global climate. The use of sustainable alternative jet fuels (SAJF) to reduce aircraft emissions will become significantly more important in coming years. Capturing the air quality benefits in a way that is useful to airports requires understanding how SAJF reduce pollutan...

TRB’s Airport Cooperative Research Program (ACRP) Web-Only Document 40 outlines the key research gaps and areas of topics of interest for airports in the design and construction field over the next five years. The research ideas generated as part of this project are organized into seven high‐level themes that represent the main areas and challenges of interest to airports in design and constructio...
