This study aims to obtain a description of whether there is an influence between the movement of wide-body aircraft both departure and arrival on flight delays as a measure of the smooth flow of flight traffic at the Makassar Air Traffic Service Center. The research concludes that there is a positive relationship between the operation of wide-body aircraft and flight delays of 0.870. The positive correlation indicates that the more wide-body aircraft operations, the flight delay will increase, which if there is an increase in flight delays, the smooth flow of flight traffic will decrease. The coefficient of determination is 75%, which means that the effect of the operation of wide-body aircraft on flight delays is 75% and the rest is determined by other factors not included in the research section. The equation obtained from the regression test is Y = -5,679 + 1,872 X. So, if the operation of wide-body aircraft increases by 1, the flight delay will increase by 1,872 at a constant of -5,679.
Supadio International Airport is an airport that serves various types of aircraft (Boeing, Airbus, ATR, Hawk, CN259), and does not have a rapid exit taxiway, in its guidance, Perum LPPNPI Pontianak Branch Office enforces rules for Boeing and Airbus-type arrival traffic for backtrack at the end of the runway, but this rule does not apply to aircraft with other types such as ATR and Cessna. This of course creates a time difference to clear the runway for arrival traffic of the Airbus and Boeing types. This study aims to obtain a safe distance between arrival traffic and departure traffic at the Perum LPPNPI Pontianak Branch Office by applying the calculation of The Brazilian Air Navigation Management Center (CGNA) Runway Capacity Calculation by adjusting the current airport conditions. From the research results, it is found that the value of the safe distance between arrival traffic and departure traffic by considering the aircraft classification can produce a more optimal safe distance.
This research was conducted at the Jakarta Air Traffic Service Center (JATSC) starting from March 2020 to July 2020 using the quantitative associative correlation method. The research population was all departing aircraft at Soekarno-Hatta International Airport using various runways and taxiways and aprons. The samples used were all aircraft departing from Soekarno-Hatta International Airport and navigation services were provided by the Jakarta Air Traffic Service Center (JATSC) in three, namely from November 2019 to January 2020 and using cluster (area) sampling techniques. The data collection technique used is a documentation study containing data on the fulfillment of Target Take Off Time (TTOT) and data on each aircraft movement required for research (such as aircraft identification, Estimate Off Block Time, taxitime, etc.). Furthermore, the data analysis technique use disparametric statistics in the form of data assumption tests followed by relationship analysis tests.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
