The pie graph below illustrates the various causes of aircraft delays in a specific Asian nation in 2015 and 2016.
Overall, the percentage of delays due to the airline operations management is the largest whereas the percentage of air traffic control as a cause of delays decreased twice.
To begin, among other causes of delays the management of airline operations comprised approximately half of the graph. It stood at roughly 40% in 2015, only to increase significantly to 46% in 2016. Nevertheless, the monitoring of air traffic accounted for 25% of causes in 2015, but it shrank almost twice to 12% in 2016.
While the amount of airport security as a reason also grew almost threefold, jumping from 4% to 13%, the percentage of military factors went down gradually from 10% to 6% during the period from 2015 to 2016. Only the percentage of unfavorable weather remained relatively steady throughout the one year period .
