With this capstone, we want to show the possibility of increasing the cost performance of airline training by providing alternatives to airlines. The idea is to promote synergy between …

Assessing Impacts Of Decentralizing Airpower Command And Control, Allen Goodwin Peck

Doctoral Dissertations and Master's Theses

Centralized control is a fundamental tenet of joint airpower doctrine, yet there are operational situations in which some degree of decentralization may be appropriate. The purpose of this research was to quantitatively assess the impacts of decentralizing the command and control (C2) of airpower under varying operational conditions. The research used the experimental method to test hypotheses regarding decentralization of control. JAEX, a stochastic, attrition-based Blue-versus-Red war gaming model, generated the required data.

The mean difference between JAEX outcomes under centralized control and outcomes under decentralized control constituted the dependent variable for each experiment. The independent variables were the operational …

Competency Based Education: A Framework For A More Efficient And Safer Aviation Industry, Flavio A. C. Mendonca Ph.D., Julius Keller Ph.D., Brian G. Dillman Ph.D.

Publications

Aircraft design and reliability as well as pilots’ education and training have steadily and significantly improved in the last 20 years. Nevertheless, high-profile accidents still occur, even when the aircraft and related systems are operating adequately. Controlled flight into terrain, runway incursions accidents, and loss-of-control-in-flight are examples of mishaps in which inadequate decision-making, poor leadership, and ineffective communication are frequently cited as contributing factors. Conversely, the investigation of accidents (e.g., US Airways Flight 1549, in US, in 01/15/2009) and serious incidents (e.g., JJ 3756, in Brazil, in 06/17/2011) have indicated that flight crews have to be flexible and adaptable, think …

The Effect Of Experiential Education On Pilots' Vfr Into Imc Decision-Making, Geoffrey R. Whitehurst, Lori Brown, William G. Rantz, Dominic Nicolai, Jessica M. Bradley

Journal of Aviation/Aerospace Education & Research

In aviation, safety is always a primary consideration, and this is especially true during a pilot’s flight training to instill that safety mentality. However, this means that pilots are restricted by safety policies from encountering difficult weather situations during their training, which could, potentially, improve their weather decision-making skills for avoiding future hazardous weather encounters. Thirty-six general aviation pilots of varying instrument flight experience (IF) were allocated, using stratified random sampling based on their IF, to one of three groups, a control group and two educational treatment intervention groups. The educational treatment interventions were designed to improve the participant’s ability …
