Motion Cueing for Stall Recovery Training in Commercial Transport Simulators

Starting in 2019, airline pilots will be required to perform full stall recovery training in flight simulators. Historically, training simulators weren't required to provide training at conditions outside their normal flight envelope. Post-stall aircraft models are generally required to be implemented to simulate the aircraft response after the stall point. In addition, motion cues need to adequately represent this response to ensure the skills learned in simulator training are directly usable in real flight. This paper provides and overview of six simulator experiments conducted at NASA Ames Research Center to develop a motion cueing strategies for stall recovery training in commercial transport simulators. One of the experiments verified an enhanced motion cueing strategy for stall recovery training on a level-D-certified full flight simulator. This study showed that the enhanced motion results in lower maximum roll angles in the stall maneuver, lower minimum load factors in the recovery, lower numbers of secondary stick shakers in the stall recovery, and a lower maximum airspeed in the recovery. These results indicate that relatively minor enhancements to the motion logic of heritage commercial transport simulators can significantly improve pilot performance in simulated stall recoveries, and potentially improve stall recovery training

Research Recommendations from the Airplane Simulation Transfer Literature

This descriptive review aims to identify research gaps in the airplane, simulation transfer of training literature. The research question is: What are the recommendations for future research from the simulation experiments using a true transfer or a quasi-transfer design to study the near or far transfer of airplane flying knowledge, skills, or abilities among adults? The method involves an exhaustive survey of English-language, peer-reviewed publications available online. The results include eight seminal reviews of the aviation literature published since 1973, 26 empirical studies published since 2004, and four general reviews to situate the aviation literature. The primary transfer studies encompass four themes: training proficiency, motion, abnormal events, and control tasks. This review addresses current research needs by presenting summaries and recommendations from the transfer literature, identifying gaps, and proposing an agenda for future research. It serves to inform researchers, practitioners, manufacturers, and regulators in the field of flight simulation training

An investigation of task specific motion cues for rotorcraft simulators

© 2016, American Institute of Aeronautics and Astronautics Inc. All rights reserved. The relevance of motion cueing in flight simulation is a widely debated topic. The aim of this paper is to present the results from a preliminary investigation of the effect of motion cueing on the perceived training effectiveness of a rotorcraft flight simulator. The paper shows the results from a series of simulator experiments that examined the effect of motion cueing on task performance and workload for a range of test maneuvers. Three test pilots flew three different rotorcraft models, with different levels of handling qualities, through test maneuvers which required different levels of task aggressiveness. The pilots used the Simulator Fidelity and Motion Fidelity rating scales, developed at the University of Liverpool, to make subjective assessments of simulator fidelity together with the Cooper Harper Handling Qualities scale. Results show that simulator fidelity requirements are not only tasked based, but are also dependent on the handling qualities of the aircraft being flown

The command team experimental test-bed stage 1: design and build of a submarine command room simulator

The command room system has developed across a century of submarine operations and so reflects a high state of evolution, but that does not mean that the system cannot be improved upon. Technological advances have resulted in the retrospective fitting of upgrades which may not have maximized the potential improvements offered. Future challenges for command teams in almost every domain include increasing amounts of data coupled with more automated systems and reduced manning. To optimise functionality new physical layouts, team structures, allocation of system functions, communication media, interfaces, and work design will be required. The aim of the ComTET (Command Team Experimental Test-Bed) project is to examine how a submarine command team currently functions, with specific regard to how information flows around the socio technical system. This information shall be used to evaluate limitations in the current system, promote ideas concerning where reduced crewing might be possible and highlight how extra data might best be integrated into the system. Phase 1 of ComTET involved the creation of a submarine command room with high physical and task fidelity. The ComTET team has designed and built a submarine command room simulator that is a representation of the currently operational ASTUTE submarine. The simulator is comprised of 10 workstations each with two stacked monitors, various input devices and a headset linked to a multi-channel communications network. The simulation engine is a custom build of Dangerous Waters software, a naval warfare simulation game. The software features many operator-controllable units from on board a submarine, allowing the completion of individual submariner command team tasks simultaneously to fulfil global (team) mission objectives. The ComTET laboratory has a range of devices for recording the personal communications of each operator, in addition to video recordings of each operator and ambient voice/video recordings. This will facilitate the construction of social, task and information networks to examine the command room from a socio-technical perspective. The laboratory is also equipped with physiological recording devices so that the workload of operatives can be examined using psycho-physiological approaches alongside commonly used standardised measures of workload, situation awareness and cognitive function. The data collected shall be based around three scenarios which capture the primary operations routinely completed by submariners in high and low work load condition

Transfer-of-Training Research at NASA Ames Research Center

In this presentation, I will first give an overview of some of the research being performed at the Human Systems Integration Division of NASAs Ames Research Center. In the second part of the presentation, I will discuss two studies that investigate the effects of simulator motion on pilot transfer of training. In a study funded by the Federal Aviation Administration, task performance is used to investigate the effects of motion on the training of 4 challenging tasks in a transport category aircraft. In addition, the effectiveness of recently proposed objective motion cueing criteria for training simulators are evaluated. The second study, part of the NASA Aeronautics Research Program, focuses on optimizing simulator motion for maximum transfer of stall recovery training and utilizes a cybernetic approach to measure transfer of training

Simulated pilot-in-the-loop testing of handling qualities of the flexible wing aircraft

© 2020 The Author(s). Published by VGTU Press. This article aims to indicate the differences between rigid and flexible wing aircraft flying (FQ) and handling (HQ) qualities. The Simulation Framework for Flexible Aircraft was used to provide a generic cockpit environment and a piloted mathematical model of a bare airframe generic high aspect ratio wing aircraft (GA) model. Three highly qualified test pilots participated in the piloted simulation trials campaign and flew the GA model with both rigid and flexible wing configurations. The results showed a negligible difference for the longitudinal HQs between rigid and flexible wing aircraft. However, significant changes were indicated for the lateral/directional HQs of the flexible wing aircraft. A wing ratcheting phenomenon manifested itself during the roll mode tests, the spiral mode exhibited neutral stability and the Dutch roll mode shape changed from a horizontal to a vertical ellipse. The slalom task flight tests, performed to assess the FQs of the aircraft, revealed the degradation of both the longitudinal and lateral/directional FQs

Time-Varying Manual Control Identification in a Stall Recovery Task Under Different Simulator Motion Conditions

This paper adds data to help the development of simulator motion cueing guidelines for stall recovery training by identifying time-varying manual control behavior in a stall recovery task under different simulator motion conditions. A study was conducted with seventeen general aviation pilots in the NASA Ames Vertical Motion Simulator. Pilots had to follow a flight director through four stages of a high-altitude stall task. A time-varying identification method was used to quantify how pilot manual control parameters change throughout different stages of the task in both roll and pitch. Four motion configurations were used: no motion, generic hexapod motion, enhanced hexapod motion and full motion. Pilot performance was highest for the enhanced hexapod and full motion configurations in both roll and pitch, and the lowest without motion. In the roll axis, the pilot position gain did not significantly change throughout the stall task, but was the lowest for the condition with no motion. The pilot roll velocity gain was significantly different between motion conditions, the largest difference being found close to the stall point. The enhanced hexapod motion condition had the highest pilot roll velocity gain. In the pitch axis, the pilot position gain was significantly different between time segments but not between motion conditions. The pilot pitch velocity gain was highest for the full motion condition and increased close to the stall point, but did not change significantly for the other motion conditions. Overall, pilot control behavior under enhanced hexapod motion was most similar to that under full aircraft motion. This indicates that motion cueing for stall recovery training on hexapod simulators might be improved by using the principles behind the enhanced hexapod motion configuration
