Recurrent On-Duty Sleepiness and Alertness Management Strategies in Long-Haul Airline Pilots
Introduction We examined whether long-haul airline pilots without recurrent on-duty sleepiness obtain more prior sleep and use more effective in-flight alertness management strategies than their colleagues with recurrent on-duty sleepiness. Methods There were 51 pilots who flew at least twice from Helsinki to Asia. Of them, 44 flew at least twice back to Helsinki following 1 local night. On-duty sleepiness was measured by the Karolinska Sleepiness Scale (KSS), alertness management strategies by a diary, and sleep by a diary and activity monitor. Pilots who rated KSS ≥ 7 on each, some, or none of the flights were classified as "regularly", "sometimes", and "never" sleepy, respectively. This …
Self-reported reasons for on-duty sleepiness among commercial airline pilots
Experimental and epidemiological research has shown that human sleepiness is determined especially by the circadian and homeostatic processes. The present field study examined which work-related factors airline pilots perceive as causing on-duty sleepiness during short-haul and long-haul flights. In addition, the association between the perceived reasons for sleepiness and actual sleepiness levels was examined, as well as the association between reporting inadequate sleep causing sleepiness and actual sleep-wake history. The study sample consisted of 29 long-haul (LH) pilots, 28 short-haul (SH) pilots, and 29 mixed fleet pilots (flying both SH and LH flights), each of whom participated in a…
Sleep, alertness and alertness management among commercial airline pilots on short-haul and long-haul flights
Item does not contain fulltext Airline pilots' sleep and on-duty alertness are important focus areas in commercial aviation. Until now, studies pertaining to this topic have mainly focused on specific characteristics of flights and thus a comprehensive picture of the matter is not well established. In addition, research knowledge of what airline pilots actually do to maintain their alertness while being on duty is scarce. To address these gaps in research knowledge, we conducted a field study on a representative sample of the airline pilots of a medium-sized airline. The sample consisted of 90 pilots, of whom 30 flew long-haul (LH) routes, 30 short-haul (SH) routes, and 30 flew both. A tota…
Faith and Worldview Communities and Their Leaders–Inward or Outward Looking?
This chapter analyzes some of the ways that the faith and worldview communities deal with the growing religious diversity. The first part outlines the development of the “interfaith infrastructures” during the past decades. There has been a growth of interfaith bodies and religious umbrella organizations in all the five countries. These bodies are stronger at the national level in Norway and Finland, while local bodies are important in Sweden. The second part analyzes interview data of Norwegian national religious leaders, which show that most of them have an outward orientation and participate in bridgebuilding activities. The growth in the interfaith infrastructure has contributed to a de…
