However, previous studies have demonstrated that failures of automated systems have significantly impaired pilots' situational awareness. The increased application of automation and the trend of pilots to rely on automation have changed pilot's role from an operator to a supervisor in the cockpit. Based on the analysis of 257 ASRS reports, the result demonstrated that pilots represent the last line of defense during automation failures, though sometimes pilots did commit active failures combined with automation-induced human errors. Current research found that automation breakdown has direct associated with 4 categories of precondition of unsafe acts, including 'adverse mental states', 'CRM', 'personal readiness', and 'technology environment'. Furthermore, the presence of 'CRM' almost 3.6 times, 12.7 times, 2.9 times, and 4 times more likely to occur concomitant failures in the categories of 'decision-errors', 'skill-based error', 'perceptual errors', and 'violations'. Therefore, CRM is the most critical category for developing intervention of Human-Automation Interaction (HAI) issues to improve aviation safety. The study of human factors in automated cockpit is critical to understand how incidents/accidents had developed and how they could be prevented. Future HAI research should continue to increase the reliability of automation on the flight deck, develop backup systems for the occasional failures of cockpit automation, and train flight crews with competence of CRM skills in response to automation breakdowns.","PeriodicalId":335344,"journal":{"name":"Journal of aeronautics, astronautics and aviation, Series A","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128515200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the landing procedure for a fixed-wing UAV is different from civil aviation, the landing data collected from real flight tests were analysed to design the automatic landing strategy. The adopted experimental platform is the Spoonbill-100 (SP-100) UAV system which was designed by the Remotely Piloted Vehicle & Micro Satellite Research Laboratory (RMRL) at National Cheng Kung University (NCKU). To boost the process of development and verification, the fuzzy logic control (FLC) was utilized to design the flight control system which includes lateral control, longitudinal control, and navigation strategy. Furthermore, an adaptive fuzzy control was applied to the altitude control for switching the membership functions of the fuzzy controller. The adaptive altitude control made the UAV have better performance during landing process. Finally, the designed automatic landing strategy and autonomous flight control was verified by using the developed HIL simulation system and a real flight test platform. The simulation and real flight test results show that the proposed automatic landing system can achieve the requirements of automatic landing procedure for SP-100 UAV.","PeriodicalId":335344,"journal":{"name":"Journal of aeronautics, astronautics and aviation, Series A","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115669751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The wing is a flat plate with rectangular planform and leading edge pivot axis at reduced pitch rates in a range of 0-0.13. The measurements were conducted using direct force measurement, dye flow visualization, and lens-shift stereo PIV. The measurement force data show that the wing at the phase of pitch acceleration in still water produces prominent normal force; insignificant forces are observed as the wing in constant pitch rate motion. The change of constant pitch rate of the wing gives promising forces under the strike of incoming uniform flow, consequently, causing effects similar to that of camber line change. The measured lift coefficient at a given reduced pitch rate are in good agreement with the results from a quasi-steady potential flow theory before dynamic stall. The theory fails to predict the drag coefficient due to the presence of dynamic wingtip vortex formation. Effect of Reynolds number in consideration on the pitching wing is insignificant. The occurrence of force stall at high angle of attack is associated with the evolution of spanwise flow in the wake, as revealed from dye flow visualization. Held at 45-degree angle of attack the wing experiences force bumps in transition to steady state; this transient behavior depends on reduced pitch rate and the shedding of swirling flow about streamwise direction.","PeriodicalId":335344,"journal":{"name":"Journal of aeronautics, astronautics and aviation, Series A","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127865237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
