Evaluation of Eta model forecasts as a backup weather source for CTAS
Summary
Summary
Knowledge of present and future winds and temperature is important for air traffic operations in general, but is crucial for Decision Support Tools (DSTs) that rely heavily on accurately predicting trajectories of aircraft. One such tool is the Center-TRACON Automation System (CTAS) developed by NASA Ames Research Center. The Rapid...
Radar-based analysis of the efficiency of runway use
Summary
Summary
The air transportation system faces a challenge in accommodating growing air traffic despite an inability to build new runways at most major airports. One approach to alleviating congestion is to find ways of using each available runway to the maximum extent possible without violating safety standards. Some decision support tools...
The design and implementation of the new center/TRACON automation system (CTAS) weather distribution system
Summary
Summary
The National Aeronautics and Space Administration (NASA), working with the Federal Aviation Administration (FAA), is developing a suite of decision support tools, called the Center/TRACON Automation System (CTAS). CTAS tools such as the Traffic Management Advisor (TMA) and Final Approach Spacing Tool (FAST) are designed to increase the efficiency of...
Weather impacted routes for the Final Approach Spacing Tool (FAST)
Summary
Summary
This paper addresses the issue of developing weather-impacted routes for the Final Approach Spacing Tool (FAST). FAST relies on adaptation data that includes nominal terminal area routes and degrees of freedom to generate optimum landing sequences and runway assignments. However, during adverse weather some adapted routes may become unavailable due...
An operational concept for the Smart Landing Facility (SLF)
Summary
Summary
This paper describes an operational concept for the Smart Landing Facility (SLF). The SLF is proposed as a component of the Small Aircraft Transportation System (SATS) and is envisioned to utilize Communication, Navigation, Surveillance and Air Traffic Management (CNS/ATM) technologies to support higher-volume air traffic operations in a wider variety...
Common CHI for en route ATC automation in FFP1 and beyond
Summary
Summary
Unique computer-human interface (CHI) challenges are arising with the pending deployment of automation developed to assist air traffic controllers and managers. In the US, a set of Free Flight Phase 1 (FFPl) decision-support tools will provide computer generated scheduling and sequencing advice from Traffic Management Advisor (TMA) and conflict probing...
Measurements of ADS-B extended squitter performance in the Los Angeles basin region
Summary
Summary
The Los Angeles Basin ADS-B Measurement Trials provided a quantitative assessment of the existing interference environment at 1090 MHz and the surveillance performance of Mode S Extended Squitter in that environment. Redundancy in the measurement equipment and in the flight configurations chosen during the trials provided extensive cross checking capability...
Open system protocols for aviation data link applications
Summary
Summary
This paper will discuss the application of "open system" communications protocols in the design and implementation of data link applications for aviation. The term "open system" in this paper refers to a set of communications protocols whose design specification is readily open to the user community, usually via publication by...
Multilateration system development history and performance at Dallas/Ft. Worth Airport
Summary
Summary
The long search for a method to provide accurate secondary radar beacon surveillance with aircraft ID over the whole airport surface has succeeded, using the Mode S squitter and whisper shout technologies to provide signal sources on which to make multilateration position measurements. The resulting multilateration system will greatly improve...
Distribution of aviation weather hazard information: low altitude wind shear
Summary
Summary
Weather Hazard Information distribution is a necessary component for a successful system of weather hazard avoidance for aviation. It is a very important component, but not the only one. In order to be successful, a complete set of components must be included in the system: 1) Accurate Conceptual Model (Appropriate...
