Abstract

In aircraft operations, to determine the amount of fuel consumption on the aircraft, it is necessary to know the time used for holding. Holding time is influenced by the number of aircraft using runway facilities and can be calculated using queuing theory. This study aims to determine the calculation of fuel consumption on aircraft when holding at Halim Perdanakusuma International Airport using queuing theory. Data for queue calculation is based on observations on flightradar24. Fuel consumption is estimated using aircraft maximum landing weight data, turning flight performance theory and aircraft manuals. From the results of the calculation, it was found that it took 6 minutes for the aircraft to queue during holding, from this time the fuel consumption calculation was carried out on the holding pattern and obtained the most fuel consumption results on the KOMIT holding pattern, which was 241,8 kg based on queuing theory and 554,8 kg based on actual data calculations. The difference in fuel consumption results is far due to the difference in time used. The time obtained based on queuing theory is 6 minutes and is equal for each holding pattern, while the time obtained based on actual data varies from one aircraft to another. For turning flight performance capabilities, the A320 aircraft can maneuver 180º within 1 minute with the largest radius of 9.204 m in 61 seconds or 1 minute 1 second on the IMU holding pattern and a radius of 2.327 m in 60,6 seconds or 1 minute 6 seconds on the COMMIT holding pattern.

Abstract

This research investigates the correlation between cruise speed, fuel consumption, and propeller efficiency in the Cessna 172 aircraft during actual flight conditions. The study involved five test flights conducted at different cruise speeds: 87.7, 90.8, 98.4, 105.3, and 113.5 knots, each flown over 100 nautical miles at 5,000 feet altitude. Fuel consumption was calculated by comparing initial and final fuel levels, revealing that actual usage consistently exceeded the Pilot Operating Handbook (POH) estimates. For instance, at 87.7 knots, actual fuel consumption was 39.61 L/hr, significantly higher than the POH value of 21.26 L/hr. Propeller efficiency peaked at lower speeds (0.828 at 87.7 knots) and declined at higher speeds (0.628 at 113.5 knots), indicating reduced aerodynamic performance. These findings underscore the importance of selecting optimal cruise speeds to enhance fuel efficiency, reduce operational costs, and extend aircraft lifespan. The study provides practical insights for pilots and operators aiming to optimize light aircraft performance in real-world operations

Abstract

The aviation industry faces increasing pressure to improve operational efficiency and reduce carbon emissions. This study investigates the potential fuel savings and CO₂ emission reductions resulting from the implementation of Single Engine Taxi-Out (SETO) procedures for Airbus A320 aircraft operating at Soekarno-Hatta International Airport (CGK), Jakarta. Using flight operational data and taxi-out duration observations via FlightRadar24, fuel savings were estimated by comparing conventional dual-engine taxi operations to SETO procedures. Results show that adopting SETO for all A320 departures at CGK could yield annual fuel savings of approximately 8,870,960 kg, equivalent to 28,032,233 kg of CO₂ reduction. These findings demonstrate that SETO offers substantial environmental and economic benefits while aligning with ICAO’s net-zero emission targets. However, successful implementation depends on rigorous safety assessments, proper crew training, and regulatory approval.

Abstract

Bandar udara berperan penting sebagai pusat aktivitas transportasi dan ekonomi, namun peningkatan intensitas operasional penerbangan dapat menimbulkan permasalahan kebisingan yang berdampak pada kenyamanan dan kesehatan masyarakat di kawasan sekitarnya. Salah satu fase penerbangan yang berkontribusi signifikan terhadap kebisingan adalah fase pendekatan (approach), khususnya pada lintasan Instrument Landing System (ILS). Penelitian ini bertujuan untuk menganalisis jarak aman kawasan permukiman terhadap paparan kebisingan pesawat pada lintasan approach ILS Runway 24 Bandar Udara Halim Perdanakusuma. Metode yang digunakan berupa analisis teoritis tingkat kebisingan berbasis data sertifikasi kebisingan pesawat dari Federal Aviation Administration (FAA), dengan pendekatan perhitungan Sound Pressure Level (SPL) dan asumsi perambatan kebisingan di ruang bebas. Analisis dilakukan pada tiga titik lintasan approach, yaitu 1,8 nm, 3 nm, dan 6 nm, untuk beberapa tipe pesawat yang umum beroperasi. Hasil penelitian menunjukkan bahwa setiap tipe pesawat menghasilkan jarak paparan kebisingan yang berbeda, dengan jarak terjauh dihasilkan oleh Boeing 737-300 (±7,07 km), diikuti Airbus A320-214 (±4,07 km), Dassault Falcon 7X (±3,38 km), dan ATR 72-200 (±2,95 km). Evaluasi pada seluruh titik lintasan menunjukkan bahwa tingkat kebisingan yang dihasilkan masih melampaui ambang batas 55 dBA untuk kawasan permukiman. Hasil penelitian ini diharapkan dapat menjadi referensi awal dalam perencanaan tata ruang kawasan sekitar bandara serta sebagai dasar pengendalian dampak kebisingan penerbangan.   Airports play a vital role as centers of transportation and economic activity; however, increasing flight operations can generate noise issues that adversely affect the comfort and health of surrounding communities. One of the flight phases that significantly contributes to aircraft noise is the approach phase, particularly along the Instrument Landing System (ILS) flight path. This study aims to analyze the safe distance of residential areas from aircraft noise exposure along the ILS approach path of Runway 24 at Halim Perdanakusuma Airport. The research employs a theoretical noise analysis based on aircraft noise certification data issued by the Federal Aviation Administration (FAA), using a Sound Pressure Level (SPL) calculation approach with the assumption of free-field noise propagation. The analysis is conducted at three approach points, namely 1.8 nm, 3 nm, and 6 nm, for several aircraft types commonly operating at the airport. The results indicate that each aircraft type produces a different noise exposure distance, with the Boeing 737-300 generating the longest distance (approximately 7.07 km), followed by the Airbus A320-214 (approximately 4.07 km), the Dassault Falcon 7X (approximately 3.38 km), and the ATR 72-200 (approximately 2.95 km). Evaluation at all approach points shows that the noise levels exceed the 55 dBA threshold for residential areas. The findings of this study are expected to serve as an initial reference for spatial planning in airport surrounding areas and as a basis for mitigating the impact of aircraft noise.

Abstract

Penelitian ini bertujuan menganalisis respons dan umur fatigue struktur float pesawat amfibi berkapasitas 19 penumpang akibat beban pendaratan air. Struktur float aluminium 6061-T6 dimodelkan menggunakan elemen shell pada perangkat lunak Abaqus dengan analisis statik. Beban pendaratan direpresentasikan sebagai distribusi tekanan hidrodinamika sesuai CASR Part 23.533(c), sedangkan keandalan model dievaluasi melalui studi konvergensi mesh. Respons tegangan dan perpindahan dianalisis pada beban limit, beban ultimate, serta variasi kecepatan 0,95Vs0 dan 0,9Vs0. Umur fatigue dihitung menggunakan kurva S-N aluminium 6061-T6 dan koreksi Goodman berdasarkan tegangan principal maksimum. Hasil menunjukkan bahwa mesh 20 mm memberikan hasil konvergen. Pada beban limit diperoleh tegangan principal maksimum 137,42 MPa dan perpindahan 13,47 mm, sedangkan beban ultimate menghasilkan 304,8 MPa dan 29,43 mm sehingga melampaui tegangan luluh material. Penurunan kecepatan menjadi 0,95Vs0 dan 0,9Vs0 menurunkan tegangan menjadi 111 MPa dan 88,46 MPa. Estimasi umur fatigue meningkat dari 3,27x104 pendaratan pada beban limit menjadi 6,22x104 dan 1,12x105 pendaratan. Area bow-skin bawah teridentifikasi sebagai lokasi kritis pada seluruh kondisi.
