Postcombat Military Job Satisfaction Among Vietnam Helicopter Aviators

Description: This project investigated the relations between recalled job-satisfaction, ability, and task demands in Vietnam era helicopter aviators. It attempted to detect and describe factors present in a dangerous combat environment which may influence some individuals to enjoy and take satisfaction at being exposed to, creating, and participating in the dangerous and life threatening violence involved in helicopter combat. Participants were 30 pilots and crew members retired from the 335th Assault Helicopter Company who were all actively involved in combat in Vietnam from 1968 to 1970. This study found that developing a love of war is correlated with anger during combat. The love of war is not correlated with PTSD processes nor is it correlated with specific personality dimensions. The love of war research is a new area. The questions were used to operationalize the love of war represent a significant limitation. This method of operationalizing the love of war concept does not make fine discriminations has questionable content validity. To facilitate accuracy in discriminating between participants when conducting future research in the area, researchers could benefit from constructing a measure with greater content validity.

Regional airline qualifications: A study in the marketability of higher education graduates.

Description: The recent emergence and growth of the regional airlines in the United States has placed a strain on the supply of pilots that are needed for staffing scheduled flights. This present pilot shortage is presenting challenges for 2-year colleges and 4-year universities with aviation programs to produce more pilot graduates in less time to meet the staffing demands made by the regional airlines. With this shortage, the pressing issues of how to train and hire qualified pilots to fly technologically advanced regional airline jet aircraft have forced the industry to demand more aviation skills from a shrinking market of aviation pilot candidates. Colleges and universities with aviation programs have been forced to compete with outside private aviation schools on a larger scale in the training of collegiate students for airline employment opportunities. The primary purpose of this study was to expose any inadequacies in the higher-education aviation curricula and to propose changes needed to better qualify aviation students in the hiring process at regional air carriers. This study concentrated on the principle that higher education is necessary for advancing a pilot's aptitudes and abilities to perform the highly technical tasks of a professional pilot in a regional airline environment. The avenues of obtaining aviation experience along with flight certificates and ratings in an academic environment from 2-year colleges and 4-year universities with aviation programs is examined, along with qualifying these schools with the criteria regional airlines expects from new pilots hired. A survey was used to poll the pilots from two regional airlines that were based in Texas. By analyzing the responses from the returned surveys, the quality of training that existed in higher education aviation programs was revealed. The study confirmed the value of advising a path of higher education for students embarking on an aviation career as a ...

A Study of the Effects of a Systematic Program of Instruction in Helicopter Technology on Student Preferences for Kinds of Learning Experiences

Description: The problem of this study was to compare two methods of instruction in helicopter pilot ground training in terms of cost of training and support services and customer satisfaction upon completion of training. The purpose of the study was the evaluation of a specialized program of instruction taught on videotape by comparison with conventional instruction. The significance of the study was related to savings in costs of instruction per trainee. Research questions for the study sought significant differences between mean scores achieved by students receiving the two treatments. Data providing information on specific characteristics of the learners were gathered as a preliminary step to establish similarity of the students in the two groups compared. A table of random numbers was used to select subjects from the population of student pilots entering training for the Bell model 206B helicopter during the months of March, April and May 1981. Upon completion of the course, all students were asked to complete an evaluation opinionaire relating to satisfaction with selected aspects of the instructional program.

The Measurement of the Association between Aircrew Members' Flying Proficiencies and Graduate Study

Description: This ex post facto inquiry investigated the existence of an association between advanced formal education and the largely psychomotor task of flying military aircraft. The analysis of data indicated that such an association does exist. Data were analyzed by computer comparison of two separate data bases. The first data base included selected U.S. Air Force officers' educational histories. The second set of data included aircrew standardization/evaluation qualification grade scores. Individual subjects were identified, and for each subject a record was formed that included the subject's standardization flight proficiency grade and advanced educational background. Group subsets of selected variables were then recorded in 2 X 2 contingency tables and statistical calculations using chi square tests of independence were applied.
