This thesis effort emphasized the use of joystick devices to emulate pilot control, the implementation of a fully enclosed virtual flight simulator, and the utilization of low-cost NTSC-based television technology to produce a prototype. The virtual flight simulator also contained a basic set of instruments …

Usair: Balancing Terminal Facilities And Runway Capacity At Pittsburgh, Edward J. Mattern

Master's Theses - Daytona Beach

As a result of expansion and acquisition, USAir has experienced major growth in flight operations. In an effort to accommodate this expansion, a major construction project, called the Midfield Terminal project, is underway at USAir's major hub, Greater Pittsburgh International Airport (PIT). The Midfield Terminal will result in a 60 percent increase in gate capacity for USAir and lower operating costs due to its location. However, increased gates infer increased flight frequencies. PIT already operates near capacity during peak periods and runway expansion has only been discussed. This paper evaluates the conditions of USAir at PIT with regard to the …

Investigation And Evaluation Of A Computer Program To Minimize Vfr Flight Planning Errors, Peter Joseph Mcalindon

Master's Theses - Daytona Beach

The purpose of this study was to investigate the effect of computer aided flight planning on flight planning errors. Subjects were selected from the introductory flight courses at Embry-Riddle Aeronautical University. After the subjects completed a conventional VFR navigation log, they were asked to plan the return trip of the flight using a computer aided flight plan. It was initially expected that the computer aided flight plans would have fewer flight planning errors than those calculated using conventional methods. The results supported the hypothesis that flight planning errors are greatly reduced when computer aided flight planning techniques are used.

Aerodynamic Forces On Flight Crew Helmets, Timothy A. Sestak, Richard M. Howard, Chester A. Heard

Publications

Wind tunnel tests were conducted to deter- mine the aerodynamic forces generated on aircrew flight helmets. Three helmets were tested: two used by aircrews flying ejection seat aircraft in the U.S. military, the Navy HGU-33/P and the Air Force HGU-53/P; and one prototype helmet of significantly different shape and volume. Axial and normal forces were measured through a range of pitch and yaw angles. It was found that large forces exist tending to promote helmet loss during ejection, and that simple modifications to the current helmet configurations can reduce those forces by as much as 40%. It is demonstrated that …

Multidimensional Scaling Analysis Of Simulated Air Combat Maneuvering Performance Data, Donald J. Polzella, Gary B. Reid

Psychology Faculty Publications

This paper describes the decomposition of air combat maneuvering by means of multidimensional scaling (MDS). MDS analyses were applied to performance data obtained from expert and novice pilots during simulated air-to-air combat. The results of these analyses revealed that the performance of expert pilots is characterized by advantageous maneuverability and intelligent energy management. It is argued that MDS, unlike simpler metrics, permits the investigator to achieve greater insights into the underlying structure associated with performance of a complex task.

Multidimensional Scaling Analysis Of Simulated Air Combat Maneuvering Performance Data Ii: A Follow-On Study, Donald J. Polzella, Gary B. Reid

Psychology Faculty Publications

Multidimensional scaling (MDS) was applied to performance data obtained from expert and novice pilots during simulated air-to-air combat. The analyses revealed the principal performance dimensions to be TACTICAL POSITION (offensive versus defensive), TACTICS ("energy" versus "angle"), and TYPE OF MANEUVERING (low energy versus high energy). High-skilled combat performance was found to be dependent on the interaction between position advantage, intelligent management of kinetic and potential energies, and maneuverability.
