Sample Report 1
The pie charts elucidate the various factors contributing to aircraft delays across several Asian nations during the years 2015 and 2016, depicting a comparative analysis.
The general trend over the two years suggests that airline operation management remained the principal cause of delays, significantly influencing flight schedules. Notably, air traffic control and adverse weather conditions also emerged as considerable contributors to these interruptions.
In 2015, a significant 40% of delays were attributed to airline operation management. Air traffic control and adverse weather conditions were responsible for causing 25% and 21% of the delays, respectively. Additional factors included military activities, accounting for 10% of delays, and airport security issues, which were responsible for a minimal 4% of the total disruptions.
The subsequent year, 2016, saw a shift in the pattern of delays. Airline operation management escalated its influence, causing 46% of delays, marking a 6% increase from the previous year. In contrast, issues stemming from air traffic control decreased to 12%, a reduction of 13%. The incidence of delays due to adverse weather slightly increased to 23%, and airport security issues saw a significant rise, tripling to 13%. Meanwhile, military-related delays decreased, contributing to only 6% of the total, thus becoming the least common cause of flight postponements.

Sample Report 2
The pie charts provide a detailed comparison of the factors leading to aircraft delays in various Asian countries for the years 2015 and 2016.
Primarily, the charts reveal that airline operation management was the predominant cause of delays in both years. The other significant factors affecting flight punctuality included air traffic control and poor weather conditions, with varying impacts observed over the two years.
In the year 2015, airline operation management was responsible for a substantial 40% of all recorded delays. Issues with air traffic control and adverse weather conditions were also notable, causing 25% and 21% of the delays, respectively. Other less prevalent causes included military operations, which accounted for 10%, and airport security concerns, which contributed to 4% of the delays.
Transitioning to 2016, the scenario showed some shifts in the contributing factors. Airline operation management saw an increase in its impact, causing 46% of the delays—an uptick of 6% from the previous year. Conversely, air traffic control issues saw a decrease, contributing to only 12% of delays, a significant drop of 13%. The influence of adverse weather conditions slightly increased, affecting 23% of flights. Moreover, airport security issues rose markedly from 4% to 13%. Military operations, on the other hand, diminished in their effect, causing only 6% of delays and becoming the least frequent cause of disruptions.

Sample Report 3
The pie charts show the numerous causes that contributed to aircraft delays in several Asian countries in 2015 and 2016. Overall, in both years, airline operation management was the leading cause behind the delayed air travels, followed by mostly the air traffic control and poor weather conditions.
In 2015, airline operation management caused two fifths of the overall flight schedule interruptions, while one fourth and about one fifth of the total deferrals occurred because of the difficulties with air traffic control and adverse weather, respectively. Military elements were the causes behind 10 percent of the entire aircraft delays in 2015, while airport security is responsible for only 4 percent of the overall flight disruptions of a particular Asian country in 2015.
In contrast, airline operation management issues caused 6 percent more flight postponements in 2016 than that of 2015, while the air traffic control system sourced 13% fewer deferments than it caused in the previous year. However, in 2016, the impact of adverse weather and airport security issues on flight schedules grew from 21% to 23% and 4% to 13%, respectively. Military-related delays in 2016 decreased from 10% to 6%, making them the nation's least common cause of delays in all air travel.
