SARDA Pre-Sim #2 System Checkout

The SARDA team brought in two Subject-Matter Experts (SMEs) to aid with system checkout of the following topics: 1) Future Flight Central's out-the-window (OTW) visuals, 2) electronic flight strips (EFS), 3) use of traffic management initiatives (TMI), 4) scenario traffic files, and 5) operational use. Feedback for the OTW was minimal, requiring just some background color changes (from sandy to shrubbery green) to allow more contrast of arrivals prior to touchdown. The aircraft models have been upgraded to reflect current air carrier flags, fight IDs, and call sign usage (especially for merging airlines, United/Continental and Southwest/US Airways). As a result of the week's testing, the SARDA team will re-evaluate the need for representing the Runway 17L arrivals. The amount of traffic placed upon the 17L arrival would nominally warrant the opening of a second local controller position and the use of the perimeter taxiway. The SME's recommendation is to remove the 17L traffic, thus elimination of the use of the perimeter taxiway, and the second local position. The SME’s also gave recommendations on scenario generation and traffic loading profile as well as operational procedures for the pseudo-pilot to adopt for next system checkout. The team will use these recommendations to refine the SARDA algorithms and user interfaces to reduce simulation distraction and place focus on the SARDA technologies during the data collection runs. Pre-simulation #3 will take place in April. (POC: Ty Hoang)

Wyle Labs kicks off Air Quality NRA at NASA Ames

On February 15th, Dr. Brian Kim (Wyle) and Dr. Saravanan Arunachalam (University of North Carolina) presented their plans to develop modeling capabilities for predicting air quality impacts due to aircraft movements near airports. NASA is currently researching how to shorten the amount of time an aircraft spends taxiing before takeoff to alleviate some of the congestion on the airport surface. Reduced taxi times will help to eliminate unnecessary fuel burn, resulting in fewer emissions and less impact on the environment. A goal of this research is to translate those impacts into air quality metrics for particulate matter and tropospheric ozone. During this meeting the team presented an overview of air quality models and their work plan. (POC: William N. Chan)

NASA and FAA conduct operational evaluation walkthrough for the Precision Departure Release Capability

PDRC Walkthrough

NASA and FAA recently participated in a walkthrough of operational evaluation scenarios for the Precision Departure Release Capability (PDRC). NASA has developed PDRC to improve tactical departure operations through the use of surface information for en route tactical departure scheduling systems. FAA Traffic Management Coordinators from Fort Worth ARTCC and Dallas/Fort Worth TRACON and Towers exercised the PDRC system in the North Texas (NTX) Research Station laboratory. NASA researchers presented the FAA operational personnel with various display configurations and evaluation usage scenarios. The FAA participants provided valuable feedback that the research team is using to refine the system configuration and test plan. Elements of the PDRC system are currently being deployed to FAA operational areas in preparation for the operational evaluation to be conducted this spring. (POC: Shawn Engelland)
