"The purpose of this thesis was to research how well native and non-native English speakers proficiently communicated using learned Air Traffic Control (ATC) phraseology, and how well they communicated using plain phraseology. The participants in this study were Embry-Riddle Aeronautical University (ERAU) flight students at the Daytona Beach campus. This study used a sample of students from English-speaking countries and a sample of students from non-English speaking countries. A quantified study of the types of communication errors was conducted by listening to a pre-defined amount of voice communications between the Daytona Beach International Airport tower facility and ERAU flight student participants. In addition to analyzing the types of communication errors, this study determined if the participants met minimum English Language Proficiency (ELP) standards. There was no significant difference in communication errors between the two groups. Both groups met minimum English Language Proficiency (ELP) standards."--Leaf v.

This study was conducted to determine the effect of a range ring and intruder vertical rate on pilots' perception of aircraft separation as viewed on a cockpit display of traffic information. A group of 30 pilots from Embry-Riddle Aeronautical University participated as subjects. SuperCard® Version 1.6 software and a Macintosh Ilsi® personal computer were employed to generate the simulation of a cockpit display of traffic information. Each pilot monitored 80 unique scenarios in which they determined, as early as possible, what the vertical miss distance would be when a single intruder passed ownship. The pilots' decision time and perceived vertical miss distance were compiled for each scenario. Range ring did not have a significant effect on the perception of vertical miss with regards to time or error while vertical rate had a significant effect on time and error. Exploratory research was also performed on miss distance and approach angle.

This study evaluated the effects that heads-up mounted TCAS displays had on pilot response and workload. Pilot response was evaluated by: (a) response time to a traffic advisory, and (b) number of missed traffic alerts. Workload assessment was accomplished in accordance with NASA's Task Load Index (TLX). Subjects were all licensed pilots with a minimum of a private pilot license and an instrument rating. A total of 32 subjects were randomly assigned to experimental and control groups utilizing HUD-mounted, and conventional, TCAS displays respectively. Performance data was collected during computer-simulated flights, while subjective workload levels were reported at the end. It was found that HUD-mounted TCAS displays yielded better performance results (p=0.05), while resulting in significantly less workload.

"Major rapid onset disasters such as earthquakes, hurricanes, and terrorist acts have the ability to overwhelm even the most prepared and robust of countries. In such cases, the value of agile airborne relief from global donors cannot be overstated. Despite its usefulness however, airborne relief can create other logistical issues such as surpassing airport capacity to park and offload aircraft. Airflow management, or the ability to coordinate aircraft arrival slot times to optimize use of airport ramp space and offload capacity, is an invaluable remedy to this malady. Though local civil aviation authorities in an affected country retain responsibility for airspace/airflow management, no selfexporting civilian entity currently exists with the ability to coordinate airflow if host nation entities are unable to do so and request assistance. This paper highlights this airflow management capability gap and sets forth several alternatives for resolving this gap based on criteria obtained through the use of a case study methodology. Without an entity to assist an affected nation with airflow management (if needed and requested), smooth logistical flow of relief goods to those in need can be catastrophically impeded."--Abstract.

"Over the last 12 years of combat many hard lessons were learned on the importance of integrating air and ground operations. The U.S. Army Brigade Combat Team became the principal fighting formation with the responsibility of conducting operations in a nonlinear battlefield with limited resources to integrate air and ground forces to achieve the commander's intent for operations. As the number of airspace users increased with the proliferation of unmanned aerial systems and increased reliance on fixed-wing and rotary-wing air support, synchronizing operations and controlling airspace became extremely complex. In response to the challenges of conducting air ground integration, the U.S. military developed new doctrine, adopted new organizations, and updated command and control systems to facilitate efficient air ground integration from the Joint Forces Command down to the Brigade Combat Team. This thesis examines current U.S. Joint and Army doctrine, the organization of the Armored Brigade Combat Team, and the current materiel systems used to conduct air ground integration in order to determine if the Brigade Combat Team can conduct efficient air ground integration."--Abstract.
