SMART-NAS Technical Interchange Meeting with FAA Tech Center
August 13, 2015

In July 2015, the NASA Shadow Mode Assessment using Realistic Technologies for the National Airspace System (SMART NAS) Test Bed (SNTB) team met the NextGen Integration and Evaluation Capability (NIEC)/Verification and Validation (V&V) facility team led by Mr. John Frederick of the Federal Aviation Administration's (FAA's) William J. Hughes Technical Center to discuss a potential collaboration. NASA presented the SNTB five-year plan to build a test bed infrastructure and to operate as a distributed environment in a virtual location and the FAA presented their test capability needs and vision. The meetings also included tours and demonstrations of the NIEC facility and capabilities and provided an opportunity to discuss lessons learned in the FAA experience with their System of System Assessment Platform project and to discuss SMART NAS integration connectivity needs. A number of action items resulted, including plans to jointly collaborate on a V&V event using the SNTB to validate an FAA NextGen objective. (POC: Kee Palopo)



UTM Completes Second Shakeout Demonstration
August 13, 2015

In preparation for the formal Build 1 Demonstration for the Unmanned Aviation Systems (UAS) Traffic Management (UTM) subproject, scheduled for the end of August 2015, a successful flight test shakeout was completed at Crows Landing, CA, August 10-12, 2015. Crews from two external partners, the NASA Ames UTM flight demonstration team, and a team from NASA Langley, each flew several UAS flights while interacting with the prototype UTM System. The shakeout demonstration enabled the NASA team to finalize the test procedures, data collection, and software development in preparation for the larger scale demonstration. (POC: Joey Rios)



Visual-Vestibular Active Psychophysics Experiment at the Vertical Motion Simulator

Simplified Primary Flight Display

Pilot loss of control (LOC) is the leading cause of jet casualties worldwide, and the U.S. Congress has mandated that aircrews be trained in stall and upset recovery, which airlines use motion-based simulators to accomplish. However, simulator motion cueing systems must be configured to provide the best stall and recovery training. The Visual-Vestibular Active Psychophysics II (VVAP II) experiment, sponsored by NASA's Technologies for Airplane Situational Awareness (TASA) Project, is the second in a series of experiments aimed at developing cueing requirements for full stall recognition and recovery training. This experiment is being performed at the NASA Ames Vertical Motion Simulator (VMS) between July 20-September 11, 2015. The purpose of this second experiment is to develop a model of the pilot's combined motion and visual perception dynamics in the pitch/longitudinal and heave axes. The model can then be used to configure simulator motion cueing systems for stall and recovery training. The VVAP experiment consists of a simple pitch-tracking task using an aircraft math model near stall. The pilot is asked to try and keep the aircraft level while a sum-of-sines disturbance is introduced in the pitch axis. The pilot will track the disturbance in a simple primary flight display. A total of 15-20 general aviation pilots will participate in the experiment and will be asked to first train for the task with limited or no motion, and then perform the task with full motion in the pitch, longitudinal and heave axes. Measurements of simulator visual and motion stimuli and pilot control inputs will be used to estimate the parameters of the pilot model. (POC: Scott Reardon)
