The Influence Of Motivation And Investment On The Length Of Time Pilots Fly Into Degraded Weather, Bonnie M. Saxton

Master's Theses - Daytona Beach

Approximately 75% of weather-related accidents result in fatalities and are a primary safety concern in aviation. This study attempted to understand how financial motivation and time investment influence the length of time pilots fly into degraded weather. The sunk-cost effect claims that financially motivated pilots would continue longer when weather is encountered late in the flight. The results revealed that the financially motivated pilots continued longer than the non-financially motivated pilots when weather was encountered early in the flight. These results support the situation assessment hypothesis and cognitive anchoring. Specifically, how pilots assess the situation and utilize information obtained before …

Entrepreneurial Spirit In Government Managed Enterprises: Evidence From The U.S. General Aviation Airports, Vitaly S. Guzhva, Massoud Bazargan, David A. Byers

Management, Marketing and Operations - Daytona Beach

While a number of studies introduce entrepreneurship in the public sector, there is still a need for empirical research in this field. We use a survey of U.S. general aviation airport managers to investigate the benefits of entrepreneurial spirit in public sector management. The results of logistic regressions suggest that the airport managers’ beliefs in importance of self-sustainability significantly improve the likelihood of general aviation airports to be self-sustaining. On the other hand, the airport specific characteristics, such as a favorable location, county population, and others are not statistically significant in achieving self-sustainability. Our findings support the literature that argue …
