The primary benefit of reliable EDR data is to increase the fidelity, accuracy, and confidence in a variety of meteorological applications including: wake vortex predictions, Graphical Turbulence Guidance (GTG), Significant Meteorological Information (SIGMET), and Pilot Reports (PIREP). These applications will facilitate greater real time turbulence situational awareness and enhance both aviation safety and efficiency.
The FAA has assembled a team of subject matter experts from relevant domains and is reaching out to both domestic and international stakeholders to bring together a diverse and comprehensive community of interest to participate in the research project. The specific work elements of the project include: establishing the process by which the EDR performance standard will be defined, identifying the associated performance artifacts, and specifying EDR standard value and label definitions.
To initiate this project, a comprehensive literature search has been conducted to draw EDR information from scores of articles, briefings and reports. This documentation includes: what in situ calculation methods are available, how they are implemented, what data is being reported, where it is available, what implementation problems have been encountered, how the data is used, what performance is required, and how data values and label are defined. This paper introduces the project's approach, and summarizes the analysis of the literature search executed to baseline the project's assumptions.
