ICAO CAEP ISG Workgroup Kickoff Meeting
December 5, 2014

The International Civil Aviation Organization (ICAO) Committee on Aviation Environmental Protection (CAEP) has an Impact and Science Group (ISG) to provide the best possible consensus information to the committee. The ISG is co-chaired by the FAA Chief Scientist, Environment and Energy and UK Climate and Air Quality Technical Advisor. Dr. Banavar Sridhar was nominated as a US member of the ISG. The ISG has a 3-year work cycle and tasked to produce white papers on Aviation Impacts on Climate, Climate Impacts on Aviation, Aviation Impacts on Air Quality and Aviation Noise Impacts. A kickoff meeting of the working group was held on November 20, 2014 to familiarize new members and prepare for the ISG workshop during February 10-12, 2015 in Washington, DC.

Motion Cueing Experiment at the Vertical Motion Simulator
December 5, 2014

The majority of commercial pilot training is performed in hexapod motion flight simulators (see Figure 1). The performance parameters for such hexapod motion systems are often configured based on subjective, pilot opinion and thus can vary greatly between simulators of the same aircraft type. Similarly, the Federal Aviation Administration (FAA)'s motion simulator certification is also subjective, based on pilot opinion. To develop more objective motion cueing criteria for hexapod simulators, and to improve ground-based pilot training, the FAA has planned a series of experiments at NASA Ames Research Center’s Vertical Motion Simulator (VMS). The second of the three Motion Cueing 2014 Experiment (MCue2014) experiments will complete on December 10, 2014 and will be used to define the boundary for acceptable hexapod system motion cueing based on three important flight maneuvers: 1) stall at high altitude, 2) one engine failure on takeoff, 3) side step approach and landing. The large motion envelope, high fidelity motion and flexible system architecture make the VMS and ideal platform for motion cueing research (see Figure 2).

A generic mid-sized twin-engine transport aircraft math model will be used for this study. The commercial pilot test subjects will fly the three tasks described above with four motion configurations. Three of the configurations will be limited to a hexapod motion envelope and the fourth will utilize the full motion capability of the VMS. The researchers will collect flight data, performance data and pilot comments to help develop the FAA hexapod motion criteria to be provided to industry. (POC: Steve Beard)

Airport Gate Management System Demonstration at Boston Logan Airport
December 5, 2014

Mr. Tom Davis and Mr. Leighton Quon accompanied Mr. Steve Bradford, the FAA's Chief Scientist for NextGen, to a demonstration of an airport gate management system operating at the JetBlue ramp tower at the Boston Logan International Airport on December 2, 2014. Engineers from Passur Aerospace along with JetBlue operations managers hosted the meeting in which the Passur Integrated Traffic Management (PITM) platform was briefed and demonstrated. PITM provides a suite of solutions that include modeling, prediction and scheduling of aircraft pushback operations while accounting for carrier and user inputs and preferences. Passur also organized a demonstration at Raytheon in Marlborough, MA that included a more extensive suite of proposed tower automation enhancements including electronic flight strips and departure scheduling to outbound meter fixes. Discussions at both sites centered on understanding the technologies, their capabilities and their relation to NASA's Integrated Arrival, Departure, Surface (IADS) project plan that is currently under development.

Meetings with Queensland University of Technology and Boeing Australia
December 5, 2014

Aviation Systems Division staff met with Mr. Brendan Williams, Adjunct Professor from Queensland University of Technology and a Research Program Lead with Boeing Research and Technology, Australia, on December 4, 2014. Mr. Williams held discussions with Ames Research Center’s Unmanned Aircraft Systems in the National Airspace System (UAS/NAS) researchers and was provided demonstrations in the UAS/NAS team's research lab. Mr. Williams also gave presentations to division staff on “Robust Autonomy: Addressing the Certification Question” and “UAS Access to Airspace: The Australian Perspective.” This meeting was a precursor to potential future collaboration discussions between Ames ATM researchers, Queensland University, and Boeing Australia.
