ATD-2 Briefing at Collaborative Site Implementation Team (CSIT) meeting
October 4, 2018

NASA Airspace Technology Demonstration 2 (ATD-2) team members attended a Federal Aviation Administration (FAA) Collaborative Site Implementation Team (CSIT) meeting in Chicago, IL, September 26-27, 2018. The two-day event, hosted by United Airlines (UAL), included participants from NASA, the FAA Terminal Flight Data Manager (TFDM) office, and the FAA Traffic Flow Management System (TFMS) office. Participants toured Chicago O'Hare International Airport (ORD) including the UAL ramp tower and UAL Station Operation Center (SOC). During the tour the NASA and FAA participants were briefed on UAL's current day surface operations at ORD and the roles and responsibilities of the ramp tower and SOC. UAL hosted a meeting at their Willis Tower headquarters in downtown Chicago where the FAA briefed UAL on TFDM and NASA briefed UAL on ATD-2. The goal of the meeting was to familiarize UAL with the TFDM concept and requirements while also illustrating the potential benefits of a surface management system. The ATD-2 briefing consisted of an overview of the ATD-2 system in Charlotte Douglas International Airport (CLT), the accrued benefits of ATD-2 during Phase 1 operations, and the lessons learned throughout the ATD-2 project. After the briefing, UAL hosted a tour of their Network Operations Center (NOC), which acts as a centralized control center for UAL operations and synthesizes information from the various SOCs located at each airport to improve decision making across the entire UAL operations network.

US Coast Guard Small Boat Recovery Experiment at VMS
October 4, 2018

The United States Coast Guard (USCG) routinely operates large parent boats and small boats in inclement weather during rescue operations. These operations require the parent boat to launch and recover a small boat using a specialized lift system. Specifically, to successfully recover the small boat, USCG small boat operators must navigate alongside the parent boat, manually receive and control two 24-pound hooks lowered from the parent boat, and attach the hooks to lifting rings with precise timing in pitching and rolling seas (see Figure 1). This critical task is performed while operators maintain balance in waves of 10 feet or more without tethers or other assistance. Determining a safe operating envelope for this recovery task has proven challenging. Reliable tools are available to predict boat behavior during the launch and recover process, but avenues for predicting corresponding human performance during the task have been limited.

Figure 1: Small boat recovery task

The USCG, in collaboration with NASA Ames Research Center’s Aerospace Simulation Research and Development Branch (SimLabs), is using the large-displacement Vertical Motion Simulator (VMS) to conduct a set of studies to better understand the limits of human performance for the recovery task. Results of this experiment promise to shape USCG large and small boat acquisitions, as well as procedures, training, and technology development for USCG rescue operations.

Figure 2: VMS small boat recovery simulation

A VMS cab, typically used for flight simulation, has been modified to simulate the bow of a USCG Over-the-Horizon-IV (OTH-IV) small boat with a lifting-eye and hook (see Figure 2). The VMS motion system simulates three specific sea states with varying wave height and modal period. This provides a controlled environment for the USCG to investigate the operational suitability for the boat crew-member (BCM) to connect the hook to the boat’s lift-eye during the OTH-IV’s recovery missions under given sea states.
