Civil Aviation Occurrences in Indonesia

Abstract

Globally, civil air traffic has been growing rapidly in recent years, and with this growth, there has been a considerable improvement in air safety. However, in Indonesia, the recent rate of incidents and accidents in aviation is far higher than the global average. This study aims to assess civil aviation safety occurrences in Indonesia and, for the first time, to investigate factors contributing to these occurrences within commercial Indonesian aviation operations. In this study, 97 incident/accident investigation reports published by the Indonesian National Transportation Safety Committee between 2007 and 2015 were analysed. The most common occurrences involved Runway Excursions, Loss of Control In-Flight, and Controlled Flight into Terrain. In terms of the likelihoods of the occurrences and the severity of consequences, Runway Excursions were more common while Loss of Control In-Flight and Controlled Flight into Terrain events were more severe and often involved fatalities. In Indonesia, Runway Excursions were usually nonfatal and comprised 45% of the occurrences for commercial flights, compared to 34% globally. Further, in this study, weather and Crew Resource Management issues were found to be common contributing factors to the occurrences. Weather was a contributing factor for almost 50% of the occurrences involving Indonesian commercial flights. Adverse weather contributed to Loss of Visual Reference for visual flight operations in mountainous areas, which contributed to the majority of Indonesian fatal accidents. The combination of Indonesian monsoon climate and mountainous weather characteristics appears to provide many risks, mitigation of which may require specialist pilot training, particularly for multicrew aircraft. In identifying the main contributing factors, this study will hopefully provide motivation for changes in training and operations to enhance future aviation safety in Indonesia.

Identification of flight accidents causative factors base on SHELLO and improved entropy gray correlation method

“…According to equations [ 1 ]-(2), the non-dimensional processing of the index data of the risk factors of flight accidents, we can get …”

“…From a mathematical perspective, the entropy method belongs to the category of objective weight methods [ 35 , 36 ]. Calculation steps of improve entropy method Step 1: Build an evaluation matrix , as show in equations [ 1 ]. …”

“…Civil aviation transportation is an important part of the comprehensive transportation system, the development of civil aviation transportation is one of the important reference indicators for the country's comprehensive transportation establishment and modernization level. Its rapidity makes international exchanges closer and global village come true, the public's demand for aviation safety is increasing [ 1 , 2 ]. Since the beginning of the new century, China's civil aviation has experienced rapid development, taking 2006–2015 as an example, the average annual growth rate of China's civil aviation transport fleet is about 10.3% and the average annual growth rate of total transportation turnover was about 10.8%, the average annual growth rate of total aircraft movements is about 9.4% [ 3 ], but the transportation and general aviation accidents almost always exist every decade between 1950 and 2019 ( Table 1 ).…”

Seasonal climate influences on the timing of the Australian monsoon onset

“…The monsoon is generally understood to be the seasonal change from dry to wet along with a reversal of the prevailing winds (Ramage, 1971). Monsoonal climates are characterised by dry winters followed by very wet summers when, by at least one definition, over 70 % of the annual rainfall accumulates (CLIVAR, 2015;Qian et al, 2002;Zhang and Wang, 2008). With all regional monsoon systems, the seasonal monsoon onset, or the first burst of monsoon rains of the season, is a much-anticipated event with documented temporal variability (Ali et al, 2020;Fitzpatrick et al, 2015;Lisonbee et al, 2020;Parija, 2018;Pradhan et al, 2017).…”
