Technical Assistance to FAA TBFM Contractor, Lockheed Martin
March 6, 2015

The Aviation Systems Division's Software Lead, Michelle Eshow, delivered enhancements to the estimated time of arrival (ETA) validation tool that Lockheed Martin uses to validate the ETA accuracy of its Time-Based Flow Management (TBFM) tool for each formal release. NASA developed the validation tool to assist with TBFM validation, included in the Air traffic management Technology Demonstration-1 (ATD-1) technology transfer to the Federal Aviation Administration (FAA). In December 2014, representatives of Lockheed Martin, who develop TBFM under contract to the FAA, asked NASA for assistance in using the tool for their latest release, version 4.3. Ms. Eshow collaborated with Lockheed Martin to understand the causes of the tool's predictions of inaccurate TBFM performance, and refined the analysis tool. The updated tool was delivered on March 2, 2015, and has now been used to demonstrate that the latest TBFM release meets its statistical performance requirements. (POC: Michelle Eshow)

Operational Integration Assessment (OIA) Preparations Continue
March 6, 2015

The OIA Risk Mitigation (ORM) series of simulations completed its third in a series of four, which took place February 24-26, 2015 at the William J. Hughes Technical Center (WJHTC) in Atlantic City, New Jersey. Nine retired controllers, three subject matter experts (SMEs), and roughly 15 pseudo-pilots took part in the simulation. The primary objective for ORM-3 was to utilize Terminal Sequencing and Spacing (TSS)-experienced controllers to identify any performance issues, simulation artifacts, or other conditions that could pose problems in a human-in-the-loop (HITL) simulation at the WJHTC. The TSS system performed well throughout ORM-3, and the simulation successfully demonstrated aircraft executing required navigation performance (RNP) approaches to runway 26 and runway 25L in the simulation of Phoenix Airport. Currently, the simulation team is preparing for ORM-4, planned for March 10-13, 2015 at NASA Ames Research Center. ORM-4 will validate the final TSS-prototypes: Time-based Flow Management (TBFM 4.2.3) and the Raytheon-developed Standard Terminal Automation Replacement System (STARS). These prototypes will be transferred to the WJHTC on March 16th, and are expected to be used for the remainder of the OIA. (POC: Kevin Witzberger)

SMART-NAS Trajectory-Based Operations Researchers visit New York air traffic facilities
March 6, 2015

NASA team members from the SMART-NAS (Shadow Mode Assessment using Realistic Technologies for the National Airspace System) project, New York Trajectory Based Operations (TBO) subproject, visited several New York air traffic control facilities in February 2015. The team is developing and creating strategic traffic flow management decision-support and analysis tools to assist air traffic service providers in selecting and integrating various traffic management initiatives. The purpose of the trip was to expose team members and researchers (Dr. Paul Lee, Dr. Heather Arneson, and Mr. Michael Bloem of NASA Ames, and Dr. Bryan Barmore and Ms. Patricia Glaab of NASA Langley) to current Federal Aviation Administration operations and air traffic staff, as well as airline and airport operators, and to gain a better understanding of the current operational challenges in the New York area airspace. The team observed a wide range of New York operations, from the airport perspective (control towers at Newark Liberty International Airport (EWR), LaGuardia Airport (LGA), and John F. Kennedy International Airport (JFK), the United Airlines ramp control facility at EWR, and a Metering Control Center operated by the Port Authority at JFK) through the en route environment (at the New York Air Route Traffic Control Center (ZNY) in Islip, New York).
