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 …

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 …
