The objective of the Cooperative Intersection Collision Avoidance System for Violations (CICAS-V) Project is to develop and field-test a comprehensive system to reduce the number of crashes at intersections due to violations of traffic control devices (TCDs; i.e., traffic lights and stop signs). The CICAS-V system provides a salient and timely in-vehicle warning to drivers who are predicted to violate a TCD, with the aim of compelling the driver to stop. This report presents the final summary report of the CICAS-V Project.

This report documents work done to enhance terminal area aircraft performance modeling in the Federal Aviation Administration's Aviation Environmental Design Tool. A commercially available aircraft performance software tool was used to develop data in a form usable by the Aviation Environmental Design Tool. These data were compared to actual aircraft performance data measured by flight data recorder systems. The terminal area fuel consumption data was shown to average about 2% different from the measured fuel consumption for departures and about 5% different for arrivals.

As students of the faculty of Aerospace Engineering at the Technical University of Delft, The Netherlands, it is mandatory to do an internship in the first or second year of the Masters track. The total duration of the internship is set to a minimum of 3 months and is rewarded upon completion with 18 ECTS. The goal of the internship is to put the knowledge gained at the Technical University of Delft into a practical use, being either the aviation or the space field, and to familiarize students with working for a company in preparation of their professional life. There are numerous options...

This report is the final deliverable of an internship which is part of the fifth year curriculum of the faculty of Aerospace Engineering at the Delft University of Technology. The two authors had the privilege of conducting their internship at the John A. Volpe National Transportation Systems Center. There they worked in the Environmental Measurement and Modeling Division. The main assignment consisted of finding a method to model the fuel burn of turboprop aircraft flying over America's national parks. To do this the authors first had to get familiarized with the Aviation Environmental...

This analysis presents a "bottom up" projection of the potential production of alternative aviation (jet) fuels in North America (United States, Canada, and Mexico) and the European Union in the next decade. The analysis is based on available plans from individual companies and considers existing and emerging fuel production technologies. The analysis also forecasts how alternative fuels might contribute to greenhouse gas goals. Based on a review of fuel production companies' stated plans to produce jet fuel, the study incorporated company-specific data into seven scenarios varying...

This project has three main objectives. The first objective isto model noise from complete aerobatic routines for a range of aircraft. The second isto compare modeledand previously measured aircraft noise from complete aerobatic routines for a range of aircraft. The third isto model the noise from up to 50 daily aerobatic routines for a range of aircraft. The end result ofthis analysis isa matrix of modeled noise results for a range of aircraft performing a variety of aerobatic routines. The FAA can now utilize these results to help set the technical threshold for approving NEPA analyses for...

This is the secondof two volumes of the report on modeling cumulative noise from simultaneous flights. This volume examines the effect of several modeling input cases on Percent Time Audible results calculated by the Integrated Noise Model. The cases presented in this volume include changes to ambient noise input typeas well as changes to sampling duration for ambient inputs. The results are comparedwith thosepresentedin the Volume 1 report.

Area navigation (RNAV) and required navigation performance (RNP) procedures are fundamental to the implementation of a performance based navigation (PBN) system, which is a key enabling technology for the Next Generation Air Transportation System (NextGen). As new RNAV and RNP procedures are developed, they are published as chartsfor use by appropriately qualified pilots. These chartsand procedures describe paths that must be flown preciselyfor improveduse ofairspace and safety.In this document, we considerhow chartsfor both conventional and PBN procedures are designedfrom ahuman factors...

This report presents the results of the study to extend the useful attenuation range of the Approximate Method outlined in the American National Standard, "Method for Calculation of the Absorption of Sound by the Atmosphere" (ANSI S1.26-1995), and provide a basis for replacing the current Society of Automotive Engineers Aerospace Recommended Practice 866A, "Standard Values of Atmospheric Absorption as a Function of Temperatureand Humidity" (SAE ARP866A). The report describes the implementation of the one-thirdoctave-band adaptations of the ISO/ANSI pure-tone equations, and the development and...

Traffic Alert and Collision Avoidance Systems(TCAS) displaysdepict traffic advisories, resolution advisories, and information on other aircraft. Symbols for other aircraftinclude the proximate status indication where the symbolsof"proximate" (close) aircraftare filled and the symbols of "non-proximate" (more distant) aircraftare not filled. This web-based study examined the value of the proximate status indication as represented by symbol fillto assess implications for Cockpit Displays of Traffic Information (CDTIs), and found no advantage for it, only a disadvantage
