There were 193,969 wildlife strikes in the US from 1990 through 2017. Wildlife strikes annually cost the US civil aviation industry, on average, $186 million in monetary losses and 111,284 hours of aircraft downtime (Dolbeer & Begier, 2019). According to the Federal Aviation Administration (FAA), Aeronautical Decision-Making (ADM) is a systematic approach that encourages pilots to identify hazards and manage risks (FAA, 2016). Additionally, it helps aviators to make timely and safe decisions. Even though it is practically impossible to eliminate the risk of bird strikes, crewmembers play a vital role in the accident prevention process (Mendonca, Carney, & Fanjoy, …

Since 1987, the US Department of Transportation (DOT) has ordered US airlines to report baggage handling statistics. The Code of Federal Regulations (CFR), requests each U.S. carrier to report monthly the total number of passengers enplaned, and the total number of mishandled baggage reports (MBR), including lost, pilfered, damaged and delayed baggage. The U.S. DOT also created a mishandled-baggage rate, which represents the total number of MBRs divided by 1,000 passengers enplaned. This KPI is monthly published at the Air Travel Consumer Report. And it is used worldwide to make comparisons between regions, airports, and airlines, characterizing efficiency and consistency …

All around the globe, the airlines struggle to sustain profitability. They are deeply affected by the region’s economy. It goes from the fuel price and exchange rate to the level of employment and average salary. That makes it imperative to control the cost, and also to balance very well the cost and level of service. Aircraft utilization is one KPI that measures productivity. Once the airline has a high aircraft utilization, it means that the resource has been productive, hence more cost-efficient.
On the other hand, flight cancelations and delays result in costs and passengers’ dissatisfaction. In Brazil, there is …

Aircraft design and reliability as well as pilots’ education and training have steadily and significantly improved in the last 20 years. Nevertheless, high-profile accidents still occur, even when the aircraft and related systems are operating adequately. Controlled flight into terrain, runway incursions accidents, and loss-of-control-in-flight are examples of mishaps in which inadequate decision-making, poor leadership, and ineffective communication are frequently cited as contributing factors. Conversely, the investigation of accidents (e.g., US Airways Flight 1549, in US, in 01/15/2009) and serious incidents (e.g., JJ 3756, in Brazil, in 06/17/2011) have indicated that flight crews have to be flexible and adaptable, think …

(1) Background: Flying in instrument meteorological conditions (IMC) carries an elevated risk of fatal outcome for general aviation (GA) pilots. For the typical GA flight, aerodrome-specific forecasts (Terminal Aerodrome Forecast (TAF), Localized Aviation Model Output Statistics Program (LAMP)) assist the airman in pre-determining whether a flight can be safely undertaken. While LAMP forecasts are more prevalent at GA-frequented aerodromes, the Federal Aviation Administration (FAA) recommends that this tool be used as supplementary to the TAF only. Herein, the predictive accuracy of LAMP for ceiling flight categories of visual flight rules (VFR) and instrument flight rules (IFR) was determined. (2) Methods: …
