Within numerous possibilities, Cost Index (CI) is the tool that can provide economic speeds and deliver the lowest cost for a given flight. Cost Index is a highly volatile number that shifts its optimum value in several different circumstances. Through the analysis of the Brazilian regulation, operation and infrastructure reality, this paper reviews several influencers that can interfere with the optimum CI value for a specific flight, aiming for maximum precision and economy. A structured questionnaire was submitted to pilots from four of the biggest Brazilian airliners operating under part 121. The purpose of this questionnaire was to investigate whether …

Effects Of Lighting And Noise On Performance And Situation Awareness In An Air Traffic Control Task, Saralee Pruksaritanon, Andrew Dattel Ph.D., Steven Hampton Ed.D.
National Training Aircraft Symposium (NTAS)
Work environment influences an individual’s performance and situation awareness (SA). This study aims to investigate the effects of lighting and noise levels on performance and situation awareness in an air traffic control (ATC) task. These two variables are important in the domain of ATC because the task requires an individual to receive and process information both visually and auditorily. The results are useful for designing air traffic control rooms, which are set differently among different air navigation service providers. The subjects are 16 students majoring in Air Traffic Management (ATM) at Embry-Riddle Aeronautical University (ERAU) – Daytona Beach, FL. The …
