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
