NASA's Contributions to Aeronautics: Flight environment, operations, flight testing, and research
Two-volume collection of case studies on aspects of NACA-NASA research by noted engineers, airmen, historians, museum curators, journalists, and independent scholars. Explores various aspects of how NACA-NASA research took aeronautics from the subsonic to the hypersonic era.-publisher description.

Piloted Simulation Assessment of a High-Speed Civil Transport Configuration
An assessment of a proposed configuration of a high-speed civil transport was conducted by using NASA and industry research pilots. The assessment was conducted to evaluate operational aspects of the configuration from a pilot's perspective, with the primary goal being to identify potential deficiencies in the configuration. The configuration was evaluated within and at the limits of the design operating envelope to determine the suitability of the configuration to maneuver in a typical mission as well as in emergency Or envelope-limit conditions. The Cooper-Harper rating scale was used to evaluate the flying qualities of the configuration. A summary flying qualities metric was also calculated. The assessment was performed in the Langley six-degree-of-freedom Visual Motion Simulator. The effect of a restricted cockpit field-of-view due to obstruction by the vehicle nose was not included in this study.
Human Factors in Aviation
Fully updated and expanded, the second edition of Human Factors in Aviation serves the needs of the widespread aviation community - students, engineers, scientists, pilots, managers and government personnel. Offering a comprehensive overview the volume covers topics such as pilot performance, human factors in aircraft design, vehicles and systems and NextGen issues. The need for an up-to-date, scienti?cally rigorous overview is underscored by the frequency with which human factors/crew error cause aviation accidents, pervasiveness of human error in safety breakdowns. Technical and communication advances, diminishing airspace and the priority of aviation safety all contribute to the generation of new human factors problems and the more extensive range of solutions. Now more than ever a solid foundation from which to begin addressing these issues is needed. New edition thoroughly updated with 50% new material, offering full coverage of NexGen and other modern issues Liberal use of case examples exposes students to real-world examples of dangers and solutions Website with study questions and image collection
On Subscale Flight Testing
Downscaled physical models, also referred to as subscale models, have played an essential role in the investigation of the complex physics of flight until the recent disruption of numerical simulation. Despite the fact that improvements in computational methods are slowly pushing experimental techniques towards a secondary role as verification or calibration tools, real-world testing of physical prototypes still provides an unmatched confidence. Physical models are very effective at revealing issues that are sometimes not correctly identified in the virtual domain, and hence can be a valuable complement to other design tools. But traditional wind-tunnel testing cannot always meet all of the ...
Piloted Simulation Study of a Dual Thrust-Cutback Procedure for Reducing High-Speed Civil Transport Takeoff Noise Levels
A piloted simulation study was performed for the purpose of indicating the noise reduction benefits and piloting performance that could occur for a typical 4-engine high-Speed Civil Transport (HSCT) configuration during takeoff when a dual thrust-cutback procedure was employed with throttle operation under direct computer control. Two thrust cutbacks were employed with the first cutback performed while the vehicle was accelerating on the run-way and the second cutback performed at a distance farther downrange. Added vehicle performance improvements included the incorporation of high-lift increments into the aerodynamic database of the vehicle and the use of limited engine oversizing. Four single-stream turbine bypass engines that had no noise suppression of any kind were used with this configuration. This approach permitted establishing the additional noise suppression level that was needed to meet Federal Air Regulation Part 36 Stage 3 noise levels for subsonic commercial jet aircraft. Noise level results were calculated with the jet mixing and shock noise modules of the Aircraft Noise Prediction Program (ANOPP).
