Abstract

The implementation of the Integrated Operations Control Center (IOCC) is an airline operational innovation to create a more integrated and responsive system. In this context, the Flight Operation Officer (FOO) plays a strategic role in designing and overseeing flight operations. The purpose of this study was to determine the extent to which the FOO's perceptions influence the effectiveness of the IOCC in supporting airline operations. Using a descriptive quantitative approach, data were obtained through a survey of 20 active FOOs using a Likert-based questionnaire, then analyzed using descriptive statistics and simple linear regression. The results showed that the FOO's perceptions of the IOCC tended to be positive, with the coordination aspect receiving the highest rating. Regression tests revealed a significant influence between the FOO's perceptions and system effectiveness (p < 0.05; R² = 0.62). These findings indicate that the effectiveness of the IOCC depends not only on the technological aspect, but also on user involvement and perspectives. Therefore, strengthening cross-functional training and improving the internal communication system are important steps to support the FOO's role in optimally implementing integrated operations.

Abstract

Aerodynamic principles are crucial for improving both efficiency and safety in commercial aircraft operations. This study compares three gliding strategies: (1) iterative calculation at a fixed 3° glide angle, (2) analysis of actual flight data from FlightRadar24, and (3) aerodynamic optimization using the drag polar method. The iterative approach produced relatively low descent rates 4.6–5.5 m/s and the longest glide times 1,100–1,323 s, offering safety benefits by enabling aircraft to reach more distant landing sites during emergencies. Actual flight data showed wider variations in descent rates 4.8–17.88 m/s and glide times 340–1,270 s due to operational requirements and ATC instructions. In contrast, aerodynamic optimization identified an ideal glide angle of 3.1°–4.1°, with higher descent rates 10.56–16.65 m/s but shorter glide times 366–577 s, representing the most efficient aerodynamic condition at maximum lift-to-drag ratio. Comparative analysis revealed that optimization median 512 s and actual data median 590 s yield greater aerodynamic efficiency, while the 3° fixed-angle approach median 1,186 s enhances safety margins. These results emphasize that glide strategy selection must balance efficiency and safety, integrating aerodynamic analysis with real operational data to support decision-making in commercial aviation

Abstract

This study evaluates the impact of the operational transfer from Husein Sastranegara Airport to Kertajati International Airport, focusing on airline On-Time Performance (OTP) before and after the transition. The research utilizes real-time flight data from Flightradar24 and secondary data from Angkasa Pura II to analyze daily flight schedules for one month prior to (October 2023) and after (April 2024) the transfer. The data is processed to determine percentages of on-time performance, delays, and flight cancellations at both airports. Findings reveal that post-transfer, the total number of flights decreased by 5.20%, while on-time performance improved by 8.81%, from 55.78% at Husein Sastranegara Airport to 64.02% at Kertajati International Airport. Additionally, flight delays reduced by 38.56%, suggesting enhanced operational efficiency. However, the number of flight cancellations rose from 0 at Husein Sastranegara Airport to 24 at Kertajati International Airport, indicating challenges in operational adjustment at the new facility. Key factors influencing delays include military aircraft movements, weather conditions, and the operational adjustments required following the airport transfer.

Abstract

An airplane is a means of air transportation used to transport passengers and goods from one place to another. Just like other transportation in general, aircraft also require maintenance. One of the aircraft maintenance activities is maintenance on the Main Wheel and Brake of the aircraft which has an important role on the aircraft. In Wheel and Brake maintenance is examined in detail with various methods, one of the methods used in Wheel and Brake maintenance is the Non-Destructive Test (NDT) method. In this case, to carry out the Non-Destructive Test inspection the company must be able to distribute Manpower needs with a good and appropriate Manhour. This study aims to optimize the allocation of manpower and time (manhour) in the implementation of Non-Destructive Test (NDT) inspections at the Wheel and Brake Shop using the Vogel Approximation Method (VAM), resulting in savings in human resources and increased efficiency in the implementation of Non-Destructive Test (NDT) inspections at the Wheel and Brake Shop. From the results of the analysis, it can be seen the distribution of manhour on various NDT component jobs and it is found that using the Vogel's approximation method (VAM) calculation results in 588.3 manhours. it is known that by using the VAM method the difference obtained is 47.7 manhours faster than the actual data which is 636 manhours with a percentage of 13.2% faster.

Abstract

Regional flights in Indonesia, particularly in Kalimantan, play a crucial role in connecting remote areas and supporting local economic activities. This analysis focuses on the maximum number of flight cycles that can be operated by the Cessna 208B turboprop aircraft using various strategies within the commuter route network in Kalimantan. The objective of this research is to calculate the maximum number of flight cycles based on differences in payload influenced by several flight strategies, utilizing the Cessna 208B Information Manual. The research process begins with identifying commuter routes in Kalimantan, collecting data from the Pilot Operating Handbook for the aircraft, fuel consumption, and flight performance at specific altitudes. Among the three strategies identified, the full tank strategy allows the aircraft to carry 1,018 kg of fuel at the start of the flight, with remaining passenger weight from the Maximum Take-Off Weight, resulting in 4 flight cycles. The full passenger strategy, with 11 passengers, allows the aircraft to carry 589 kg of fuel without refueling, yielding 2 flight cycles. By employing a refueling strategy at each airport, the aircraft can carry varying amounts of fuel, resulting in 8 flight cycles. It can be concluded that the refueling strategy is the most optimal, as it generates a higher number of flight cycles. The findings from this study are expected to serve as a foundation for further research on regional aviation in Indonesia, particularly in Kalimantan

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
