Comparison Of Three Angle Of Attack (Aoa) Indicators: A Usability Study, Camilo Jimenez

Doctoral Dissertations and Master's Theses

Angle of Attack (AOA) is an important aeronautical concept used to understand the performance status of an aircraft during different flight stages. The Federal Aviation Administration (FAA) has indicated the importance of developing and encouraging the use of affordable AOA based systems to increase inflight safety. Embry-Riddle Aeronautical University's flight department decided to install AOA indicators in its fleet of Cessna 172S, to increase safety and to help student pilots better understand this important concept. This paper presents a review of AOA, visual display design principles, and usability. This experimental study examined three different AOA indicators provided by the …

Comparison Of Voice And Text Atc Communications In The Cockpit For Esl Pilots, Shannon Marie Cummings

Doctoral Dissertations and Master's Theses

Throughout the course of any flight, pilots and air traffic control (ATC) are in constant radio communication regarding the position and route of the aircraft. Effective pilot-ATC communication helps to increase safety by increasing the situation awareness of both the pilot and controller. In the current pilot-ATC communication system, auditory messages are sent back and forth between the pilot and controller. The nature of these auditory messages makes them highly susceptible to memory and information processing limitations. This effect is magnified when dealing with pilots who have learned English as a second language (ESL) as people have more difficulty processing …

A Naturalistic Study Of Long-Term Working Memory Capacity For Meaningful Visual And Auditory Stimuli, Joseph M. Jaworski

Doctoral Dissertations and Master's Theses

The purpose of this study was to explore long-term working memory in experts in an information-rich, dynamic domain. Of particular interest were strategies experts use to enhance long-term working memory capacity when working with verbal versus aural information. Three air traffic control instructors participated in four complex air traffic control scenarios, two radar scenarios in which information was presented visually and two non-radar scenarios in which information presentation was purely aural. Participants recalled traffic situation information at two points during and at the end of each scenario. Recall data for each scenario type were assessed in terms of evidence about …

Spatial Cognition Differences Between Men And Women In Spatial Cue Environments During Flight Simulation, Heidi Crystal Kim

Doctoral Dissertations and Master's Theses

Ground reference maneuvers are an important component of pilot training. In order to perform these maneuvers, pilots rely on cues from the environment to determine where their aircraft is in relation to objects on the ground. This process requires a high degree of spatial cognition, which refers to the cognitive processes used to orient oneself in space. Two factors that can influence spatial cognition in the context of aviation ground reference maneuvers are the availability of spatial cues and the biological sex of the pilot. Research suggests spatial cues aid in the identification of potentially dangerous objects. In the context …

Pre-Exposure Training As A Means To Reduce Vection Induced Symptoms Of Motion Sickness, Nicholas James Stapleton

Doctoral Dissertations and Master's Theses

The focus of this study was designed to empirically examine the effect of inducing mild motion sickness as an ameliorative to a more severe motion sickness exposure. Twenty-seven participants were selected for this study based upon their susceptibility to motion sickness, that is, only people who were determined to be motion susceptible were tested. All participants were exposed to a motion sickness-inducing environment. Eighteen participants were trained to adapt to motion sickness by exposure to a milder motion sickness-inducing environment, ending either 6 hours or 24 hours prior to the more severe motion test environment.

Participants during the pre-exposure experimental …
