Job-related attitudes of non-journeyman FAA air traffic controllers and former controllers : a sex comparison by John J Mathews( Book )

6 editions published in 1974 in English and held by 229 WorldCat member libraries worldwide

ATC attrition rates have been investigated recently for sex differences in the proportion of trainees completing FAA Academy training; the percentage of women who subsequently left ATC work was twice that of men. In the present comparison, questionnaires concerning aspects of job-related attitudes were given to 56 male and 56 female former trainees (attritions) who were matched on several variables, and also to a sample of controllers (63 women and 63 matched men) who entered training at the same time as the attritions, but who were still in ATC work (Retentions). The results are reported
Attitudes and motivational factors in terminal area air traffic control work by Roger C Smith( Book )

7 editions published in 1971 in English and held by 225 WorldCat member libraries worldwide

A sample of 614 journeymen terminal ATCSs at 17 high-density IFR airports, and 514 ATC trainees were administered a questionnaire which asked them to list what they liked best and what they liked least about ATC work in general; in addition, ATCSs made similar lists for work at their assigned facilities. Responses were surveyed for clusters, and nine response categories were established. The frequency of responses within each category was tabulated. The pattern of responses from ATCSs was noted from one facility to another. The categories of job challenge, job tasks, career characteristics, and salary contained the most positive responses about ATC work, while the categories of management, work schedule, career characteristics, and job tasks had the most negative responses. There was a high degree of similarity between these findings and results obtained in motivational studies of other professions

A comparative study of female and male air traffic controller trainees by Bart B Cobb( Book )

6 editions published in 1972 in English and held by 215 WorldCat member libraries worldwide

The study compares age, education, pre-FAA experience, aptitudes, training-course performance measures, and post-Academy attrition rates of the 83 women who entered basic air traffic control (ATC) training at the FAA Academy during November 1968 through March 1970 with those of various samples of the 3,760 males who entered training during the same period. The study revealed no significant differences between the means of the female and male trainees with respect to age and educational level. When samples of the 83 females were compared with groups of male trainees in terms of performance on 36 different aptitude tests, only four mean differences, all of which favored the females, proved statistically significant.

Aircraft-pilot and other pre-employment experience as factors in the selection of air traffic controller trainees by Bart B Cobb( Book )

8 editions published in 1974 in English and held by 215 WorldCat member libraries worldwide

This longitudinal study of 4,092 ATCS trainees examines the validities of various types of aviation-related experience, separately and in combination, for prediction of success in FAA ATC work--with success defined as retention status within the air traffic control system several years after entry into training. Of the 4,092 subjects, 1,740 entered Academy basic training during September 1960 through August 1963, before an ATC-Aptitude Testing Battery became operational in the screening of most applicants. The remaining 2,352 ATCSs, the majority of whom were selected from among aptitude-screened applicants, entered Academy training during 1969. Both groups entered prior to establishment of the current standard under which eligibility for training is restricted to personnel no older than age 30
The relationships between chronological age, length of experience, and job performance ratings of air route traffic control specialists by Bart B Cobb( Book )

6 editions published in 1967 in English and held by 214 WorldCat member libraries worldwide

The survey-type study of several hundred journeymen radar control specialists of four Air Route Traffic Control Centers was conducted in order to determine the extent to which job performance might be associative with chronological age and length of experience in control work. For each of several experimentally derived ratings of job performance, a statistically significant and negative relationship was found with age. Mean group ratings for controllers over 40 years of age were significantly lower than those of younger groups. Length of experience, when considered independently of age, was found to be of negligible importance and no statistically significant interaction effects of age and experience were discovered. However, a comparison of the data for dichotomized groups of controllers aged '40 and less' and '41 and older' revealed a higher mean rating for the younger group of controllers at every experience level. Yet these differences between the younger and older ATCSs of each experience group were nonsignificant. (Author)
A sex comparison of reasons for attrition of non-journeyman FAA air traffic controllers by John J Mathews( Book )

6 editions published in 1974 in English and held by 212 WorldCat member libraries worldwide

Recent ATC attrition rates showed no sex differences in the proportion of trainees who completed FAA Academy training; however, the percentage of females who subsequently left ATC work was over twice that of male trainees. In the present study, the 56 females who entered the Academy between December 1968 and November 1970, and who were no longer with the FAA as of June 1972, were matched on several variables with male attritions who had entered the Academy at the same time. Reasons for attrition were obtained from job-exit forms, telephone interviews, and a questionnaire. (Modified author abstract)
The relationships of age and ATC experience to job performance ratings of terminal area traffic controllers by Bart B Cobb( Book )

7 editions published between 1973 and 1974 in English and held by 211 WorldCat member libraries worldwide

The study involved the collection of experimental ratings of job performance and other data for several hundred journeymen radar control specialists of 17 high-IFR-traffic-density Terminal Area Traffic Control facilities. Significant inverse relationships were found between the job ratings and both chronological age and tenure in FAA ATC work. Results of a comparative analysis of data for dichotomized groups aged '40 and younger' and '41 and older within each of several length-of-experience groupings indicated that the younger subjects of every experience level tended to receive higher evaluations than those over 40 years old, and the greater mean differences in performance ratings pertained to the dichotomized age groups having over ten years experience. However, a regression analysis indicated that, when the than those over 40 years old, and the greater mean differences in performance ratings pertained to the dichotomized age groups having over ten years experience. However, a regression analysis indicated that, when the variance of age was theoretically nullified, or held constant, experience correlated only negligibly with performance. A similar analysis indicated that if the subjects had possessed identical amounts of experience, their ratings would still have correlated negatively, and significantly so, with their ages. Other results also suggested that ATCS proficiency is more apt to decline as a result of factors associated with aging than as a consequence of presumed effects stemming from lengthy ATC experience.

A comparative study of air traffic trainee aptitude-test measures involving Navy, Marine Corps and FAA controllers by Bart B Cobb( Book )

5 editions published in 1968 in English and held by 210 WorldCat member libraries worldwide

The study concerns the experimental use of several commercially-published aptitude tests and a determination of their validity as predictors of training-performance grades for more than 300 Marines and over 600 Naval students who entered a basic air-traffic-controller (ATC) training course. The results indicated that a composite score involving only four of the tests could be used to effectively predict performance grade and pas-fail status for the training course. The Marines were found to have been selected from relatively higher military-screening-and-classification (MSC) test score ranges than the Naval trainees and their training-course failure rate was lower.

A proposed new test for aptitude screening of air traffic controller applicants by Bart B Cobb( Book )

5 editions published in 1972 in English and held by 210 WorldCat member libraries worldwide

The study concerns the development and experimental validation of a novel aptitude test, referred to as 'Directional Headings' (or DHT), for the selection of Air Traffic Control Specialist (ATCS) trainees. The test requires the subject to rapidly interpret letters, symbols, and degrees in order to determine: directional headings (Part I), the exact opposites of headings (Part II), and opposites of headings under conditions of aural distraction (Part III). Reliability of the instrument, as determined by corelating the scores based on even-numbered items versus scores based on odd-numbered items, was .93. (Author)
Attrition-retention rates of air traffic control trainees recruited during 1960-1963 and 1968-1970 by Bart B Cobb( Book )

5 editions published in 1972 in English and held by 208 WorldCat member libraries worldwide

The study involved a total of 6,367 subjects in three ATCS options. Of these, 2,000 entered FAA Academy training during 1960 to 1963, before an ATC-Aptitude Test Battery became operational in the screening of most applicants. The remaining 4,367 subjects, the majority of whom were selected from among aptitude-screened applicants, entered the Academy's basic training courses during October 1968 through March 1970. Percentages reflecting Academy elimination rates are reported for entrants of the earlier and later time periods. (Author Modified Abstract)

Education as a factor in the selection of air traffic controller trainees by Bart B Cobb( Book )

3 editions published in 1976 in English and held by 101 WorldCat member libraries worldwide

This longitudinal study of 2,352 air traffic control specialist recruits (1,858 En Route and 494 Terminal) who entered the FAA Academy basic training phase in 1969 examined the validity of educational level, recency of education, and major areas of college study for the prediction of success in air traffic control (ATC) training. All educational variables, both before and after consideration of age effects and pre-FAA experience, were found to be negligibly and/or inversely related to ATC success. College majors listed by 925 of the 1,265 recruits who attended college revealed little potential for prediction of ATC success; even those 53 recruits whose majors were judged to be aviation related had a retention rate of only 56.6 percent compared to the 56.7 percent retention rate of all recruits indicating college work. None of the education variables had a significant interaction effect on the validities of other selection factors. Moreover, all types of aviation-related experience except ATC were found to be unreliable for prediction of training outcomes
Attitudes on en route air traffic control training and work : a comparison of recruits initially trained at the FAA Academy and recruits initially trained at assigned centers by John J Mathews( Book )

3 editions published in 1975 in English and held by 95 WorldCat member libraries worldwide

In this comparison, questionnaires concerning aspects of training-related and work-related attitudes were sent to 225 ATC trainees who represented groups of attritions and retentions in two En Route training programs; viz, programs that provided basic training at the FAA Academy and programs that provided basic training at the trainees' assigned facilities. Data from both groups generally support previous findings regarding sources of differences in work attitudes between sexes and between attrition-retention groups. The most frequent recommendations for change involved facility training and facility instructors; modifications in the pace of training were also recommended frequently
