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 …
