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.
