Abstract

Maintenance management is a series of activities that include planning, organizing, program implementation, and control methods for maintenance activities. This study aims to determine whether maintenance management practices can be implemented effectively through a hybrid training method (virtual and offline) that utilizes a maintenance management laboratory. The research stages include understanding the data that must be inputted by technical records, how to read and fill out maintenance logs, and designing virtual tutorials which are then tested on aviation engineering students. In using the virtual tutorial, students input data, calculate aircraft life utilization based on Time Since New (TSN) or Cycle Since New (CSN), and calculate the life of aircraft components with the same parameters. Based on the results of testing the AFML tutorial on 10 aviation engineering students, it was found that 96% of them were able to answer the evaluation questions correctly, with 8 students answering perfectly and 2 students reaching 80% success rate. These results show that the virtual tutorial developed is quite effective and useful in improving students' understanding of maintenance management, especially in the use and analysis of AFML data.

Abstract

Spoiler is one of the components that has an important role in an airplane. This component serves to slow down the speed of an aircraft both in the air and on the ground. However, due to its classification as part of secondary flight control, its understanding is often limited to the general public as a braking device on an aircraft without paying attention to the complexity of its functions and mechanisms. Therefore, the design of this spoiler simulation is expected to help in understanding the work simulation of a spoiler on an aircraft. This tool is designed with a simple working system using a syringe and hose as a simple depiction of the hydraulic system performance on the aircraft, which is also equipped with a series of electrical systems consisting of arduino, servo and microswitch as a support system for this tool so that it can describe the difference in performance between flight spoiler (speed brake) and ground spoiler. The wing structure of this tool is made of thermoplastic material (PLA) and mica plastic, so that it can make it easier to see how this tool can work. This tool is also equipped with a lever that is duplicated as the original according to the aircraft. Based on the design and assembly that has been done, this tool is proven to work successfully in accordance with its respective functions.

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
