One effort to reduce the risk is to minimize the controller’s workload when affected by air traffic complexity. This research uses a simulation model to measure air traffic complexity in terminal control areas. The aircraft performance model has been constructed from ADS-B data and represents the aircraft movement in the terminal control area of Soekarno-Hatta International Airport. The simulation model can detect and resolve conflicts to keep separations between aircraft at a specified minimum separation limit. Air traffic complexity measurement uses several indicators, i.e., aircraft density, number of climbing and descending aircraft, aircraft type mixing, conflict control, aircraft speed difference, and controller communication. The weighting factor for each indicator has been obtained from Jakarta Air Traffic Service Center (JATSC) controller perception using an analytic hierarchy process. The simul...

CROPA merupakan metode pengaturan jadwal kerja crew. Tujuan utama pembuatan CROPA adalah memaksimalkan waktu kerja crew, sehingga rute perjalan suatu crew dapat bertambah. Penambahan rute untuk suatu crew dapat menyebabkan jumlah kebutuhan crew pada suatu airline berkurang. Sebagai contoh, saat seorang crew maksimal melakukan 4 rute perjalanan, dan airline mempunyai 40 rute perjalanan, maka airline membutuhkan minimal 10 orang crew. Namun dengan bertambahnya rute perjalanan seorang crew menjadi 5 rute perjalanan, maka airline dapat mengurangi kebutuhan crew menjadi 8 orang crew. Pengurangan kebutuhan crew ini menyebabkan biaya operasional yang dikeluarkan perusahaan dapat menjadi lebih kecil. Selain itu, pembuatan CROPA juga mempertimbangkan masalah kemanusiaan seperti waktu kerja dan waktu istirahat crew yang cukup, sehingga dapat meningkatkan kepuasan crew.

ADS-B data processing to develop aircraft kinematics model parameters

One method used to determine the aircraft kinematics model parameters is to extract flight performance parameter data obtained from the Automatic Dependent Surveillance-Broadcast (ADS-B) data. The ADS-B data can be collected from ADS-B open source databases such as FlightRadar24. The flight performance parameters model is developed for takeoff , initial climb, climb, descent, and final approach phases for the aircraft kinematics model. This data will then go through data collecting, data pre-processing, and data processing to obtain the best-estimated flight performance parameters to be applied to the ATM simulator aircraft kinematics model. In this paper, the ADS-B data processing step is explained to get the flight parameters for a specific flight phase.

This study aims to obtain flight parameters for aircraft operating in the terminal control area of Soekarno-Hatta International Airport using Automatic Dependent Surveillance-Broadcast (ADS-B) data, which is openly available on FlightRadar24. Flight parameters were measured for several flight phases, such as takeoff , initial climb, climb, cruise, descend, and final approach. In addition to these flight phases, flight parameters at waypoints on the arrival and departure were also measured. Furthermore, all flight parameters are modeled stochastically through the probability distribution function (PDF) approach. The best model for each parameter is obtained using the Maximum Likelihood method (MLE) with some relevant Kosmolgrove Smirnov Test criteria. The use of ADS-B data along with the stochastic model presented in this paper provides comprehensive information on flight behavior, which can be further utilized for an aircraft simulation model of an Air Traffic Management system.

In this situation, a fighter can attack the opponent before direct encounter. Its complexity arises due to the necessity to take into account the information of target’s maneuver, the specification of the missile, and the advantage of fighter position. In this paper, a simple BVR air combat system has been developed to give a fight strategy for pilot. Some important parameters are considered, such as the distance and the azimuth position of the target’s as well as the range and the energy of missile to reach the target. The information is processed to determine the fighter supremacy and the opponent’s threat factor. The result of the processing is used as an input of fuzzy logic algorithm to determine the optimal fighting strategy. The feasibility of the model and validity of the algorithm are verified by simulation under two typical situations

The isothermal flow was examined to predict the combustion stability. The simulations indicate different flow-field characteristics can be achieved under the same swirl number. In addition to swirl number, swirl velocity induces the existence of centrifugal force. This force affect velocity profile peak, static pressure profile, radially; and recirculation zone, axially.

Perhitungan Kapasitas Runway Dan Strategi Perubahan Jadwal Penerbangan Bandara Untuk Mengurangi Waktu Holding (Studi Kasus 6 Bandara Yaitu : Soekarno Hatta Jakarta, Juanda Surabaya, I Gusti Ngurah Rai Denpasar, Polonia Medan, Sepinggan Balikpapan, Hasanudin Ujung Pandang)

Kepadatan tersebut terutama terjadi karena pihak maskapai penerbangan berlomba untuk mendapatkan golden time, yakni waktu dimana demand yang terjadi saat itu sangat tinggi. Untuk mengurangi terjadinya congestion dan kepadatan yang terjadi, pihak ATC menerapkan kebijakan holding. Kebijakan holding menjadi masalah serius saat diberlakukan di udara (airborne holding), karena akan menghabiskan lebih banyak bahan bakar dan rentan terhadap terjadinya kecelakaan. Tugas akhir ini mengkaji salah satu solusi untuk mengatasi hal tersebut melalui pemodelan Multi Â– Airport Air Traffic Control untuk meminimumkan waktu holding. Konsep pemodelan tersebut diterapkan dengan menunda pesawat di bandara keberangkatan sehingga saat akan sampai di bandara tujuan, pesawat tersebut tidak pe...

They can make aggressive product differentiation using common product platforms and design commonalities. Airplane configurations can be rapidly modified to meet market demand in time with minimum development cost. This paper outlines an analysis of various airplanes designed based upon common design concepts. The designs maintain the same geometry of wing and tailplane, the same number and type of exits, and the same number and type of engines. Fuselage is extended by adding frames in front and aft of wing while maintaining the same cross section. For the baseline airplanes, the size of wing and tailplane geometry is optimized for specific seating capacities under the same set of design contraints. Derivative airplanes are modified from the baseline airplane in which fuselage frames are removed or inserted to obtain the final size of the fuselage, while maintaining the same wing and tailplane geometry as that of the baseline airplane. Analysis would then be carried out on the flight performance, stability and control characteristics of the aircraft. Based on the analysis, design constraints and limitations can be applied to the geometry and design of the derivative airplane.
