“Pavement condition data” are essential inputs to the process of managing airport pavements and ensuring safe operations. The technology available today to collect pavement condition data is considerably different from that available even 20 years ago, and new technologies are being developed and introduced into practice at a rapid pace. ACRP Research Report 203: Guidelines for Collecting, Applying, and Maintaining Pavement Condition Data at Airports provides guidance on the collection, use, maintenance,...

The unmanned aircraft systems (UAS) industry is on the cutting edge of aviation innovation. Airports, including tenants and contractors, are discovering the benefits of UAS to their operations and bottom line. Yet, with the diversity of UAS applications at airports, there has been a lack of relevant industry data on this topic to inform the airport industry on current practices. The TRB Airport Cooperative Research Program's ACRP Synthesis 104: Current Landscape of Unmanned Aircraft Systems at Airports s...

As demand for air travel grows, airport-related emissions are increasing and airports are challenged to reduce associated environmental impacts. In response, expanded regulatory programs and global climate protection initiatives are being developed that require the aviation industry—including U.S. airports—to implement new, clean technologies and to modify operational practices to reduce emissions. One effective option for reducing the emissions associated with aircraft auxiliary power units (APUs) and d...

Airports worldwide are setting aggressive zero- or low-emissions targets. To meet these targets, airports are deploying new strategies, adopting innovative financing mechanisms, and harnessing the collective influence of voluntary emissions and reporting programs. In tandem, new and affordable zero- or low-emissions technologies are rapidly becoming available at airports. The TRB Airport Cooperative Research Program's pre-publicaton draft of ACRP Research Report 220: Guidebook for Developing a Zero- or L...

Airports — especially in the past two decades—have generally sought to promote and increase collaboration among the members of the airport community, particularly between an airport and its airlines. One metric of this trend has been the increase in the number of U.S. airports with full-time emergency managers, from fewer than 10 in 2007 to more than 120 today. Collaboration and increased professionalism in airport emergency management have gone hand in hand. No matter whether the incident is aircraft-re...

Seriál „Byl jednou jeden život“ zná snad každý pod 40 let. V německé verzi tohoto populárního seriálu pro děti hodné bílé krvinky zabíjejí plynem zlé bakterie, které volají „To je hrůza!“. Volají to v židovském jazyku jidiš. Jazykové mutace v jiných zemích tento výkřik neobsahují a neobsahuje ho ani originální francouzská verze. To si toho opravdu za 35 let vysílání seriálu v Německu nikdo nevšiml? Nebo se nad tím jen dobře bavili? Na antisemitskou narážku upozornil nyní článek na německém webu zabývajícím se médii Übermedien.de.
