Title and Subtitle: Comparison of Opa Locka Tower with other ATC facilities by means of a biochemical stress index

Report Date: December 1974

Authors: Melton CE Jr, McKenzie JM, Saldivar JT, Hoffmann SM

Abstract: Physiological and biochemical measurements of stress in 14 Opa Locka Tower (OPF) controllers indicated that the principal stressor at that facility was the heavy volume of air traffic. Controllers responded to this stressor with a large increase in urinary output of catecholamines. A stress index, Cs, shows that OPF ranks second in stressfulness in the nine stress studies carried out at eight ATC facilities. Baseline values show that off-duty stress at OPF is low. The results of this study emphasize that a battery of tests is necessary for adequate definition of stress in this personnel group.
