1. 11. Conceptual Design of Propulsion Systems for Boundary Layer Ingestion

   Författare :Sebastian Samuelsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo-electric aircraft; performance modeling; Aviation; boundary layer ingestion; aircraft engine; conceptual design; propulsion integration;

   Sammanfattning : To reduce the climate impact of aviation new aircraft and engine concepts as well as improved design methods are needed. In this thesis, two fronts are explored. The first concerns improved methods for the conceptual design of the engine. LÄS MER

3. 12. Aeronautical decision-making in context: Influence of affect and experience on procedure violations

   Författare :Johan Lindvall; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aviation; Decision-making; Violations; Non-technical skills; Experience; Affect; Overconfidence;

   Sammanfattning : Although pilots are well trained and there are rules, models and standard operating procedures to use in decision-making situations, aviation accidents do occur. One reason why accidents may occur is because pilots sometimes decide to violate, or deviate from standard operating procedures. LÄS MER

4. 13. Self-rated health and respiratory symptoms among civil aviation pilots : Occupational and non-occupational risk factors

   Författare :Xi Fu; Dan Norbäck; Christer Janson; Berndt Stenberg; Uppsala universitet; []
   Nyckelord :Civil Aviation; Aircraft pilot; Indoor environment; Self-rated health SRH ; Respiratory health; Asthma; Rhinitis; Headache; Fatigue; Insom-nia; Body mass index BMI ; Sense of Coherence SOC ; Psychosocial work environment; Quantitative PCR; Fungal DNA; Volatile organic compounds of microbial origin MVOC ; Cat allergen; Dog allergen; Horse allergen;

   Sammanfattning : There is concern about the indoor environment in aircraft but few stud-ies exist on self-rated health (SRH) and respiratory symptoms among pilots. Occupational and non-occupational risk factors for SRH, respira-tory symptoms and other symptoms among commercial pilots were investigated in this thesis. LÄS MER

5. 14. Pilots’ decision-making, emotions and cognitive performance in simulated environments

   Författare :Eduardo Rosa; Johan Willander; Igor Knez; Robert Ljung; Nicklas Dahlström; Eric Groen; Högskolan i Gävle; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; aviation; pilot; simulation; environment; decision-making; fatigue; cognition; emotion; physiology; flyg; pilot; simulering; miljö; beslutsfattande; trötthet; kognition; känslor; fysiologi;

   Sammanfattning : The aim of this thesis is to investigate pilots’ performances in distinct simulation environments as related to the phenomena of cognition, emotion and fatigue. By doing so, it provides psychological material to broaden the understanding and possibility to development of pilots’ non-technical skills category related to the operational context. LÄS MER

7. 15. Exploring Levers for Improvement of Basic Civil Aviation Training

   Författare :Nicklas Dahlström; Trafikflyghögskolan; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Basic civil aviation training; Mental workload; Psychophysiology; Riskhantering; Risk Management and Safety engineering;

   Sammanfattning : Although the civil aviation industry has gone through great technological and commercial change in the last decades, basic civil aviation training has not kept pace accordingly. The changes in civil aviation have rarely resulted in research programs in the field of basic training, which has long received minimal attention from the industry. LÄS MER
