Abstract

The autoflight servo system plays a critical role in maintaining aircraft stability during automated flight operations, where sustained manual control by the pilot is impractical. Due to its integration with multiple aircraft systems, servo failures may propagate and affect overall flight control performance. This study investigates the failure characteristics, root causes, and mitigation strategies of the autoflight servo system in the Airbus A330-300 operated by International Airline X. A descriptive quantitative approach was adopted using a case study methodology. Primary data were obtained from maintenance records, technical documentation, and interviews with relevant personnel, while secondary data included historical failure reports and repair procedures. Risk Priority Number and fishbone diagram was employed to identify dominant failure mechanisms. The results indicate that failures were primarily electrical (27.91%), followed by mechanical (20.93%), hydraulic (17.44%), and human error (6.98%). Electrical failures represent the highest risk category. In response to servo failure, the system automatically transitions to Secondary Flight Control Computer (SEC) or alternate law mode, allowing pilot control via sidestick input. Preventive measures include periodic connector cleaning (1–2 years) and actuator seal monitoring through hydraulic oil particle analysis to detect early wear.

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.
