PBN operation advantage analysis over conventional navigation

Abstract: With the development of global economy and the rapid growth of people's material demand, the sustainable development of air industry needs more and more airspace capacity, so the importance of optimizing available airspace is prominent. Under the background of world aviation industry, after more than 60 years development, the safety level has steadily improved, the total amount of transportation has increased rapidly, the air routes have been enriched and the air traffic capacity has gradually improved. PBN, the performance-based navigation technology is one of the most essential topics in China’s aviation development. Compared to conventional navigation, it has witnessed significant benefit in PBN operation, such as less fuel cost, shorter route range and lighter workload of the controllers. This paper introduces the basic concept of PBN, and then selects three typical routes through simulation software, compares the characteristics of PBN and traditional navigation in practice, and illustrates the advantages of PBN procedures by means of data and charts.

Benefits for Greek Regional Airports Through Innovative Approach Technology Using an LPV to GLS Converter: A Case Study for Corfu and Thessaloniki

Abstract: Required navigation performance procedures are a cost-effective and accurate solution for aircraft instrument approaches, especially when combined with a final approach segment utilizing satellite based augmentation. However, transport category aircraft are currently not equipped with the satellite based augmentation for precision guidance. An existing converter technology can provide this final approach segment to aircraft equipped with the GPS landing system. Then, as an added bonus, an automatic landing at pilots discretion is possible after the presented approach. Here, we study Thessaloniki and Corfu airports, both accommodating a large number of transport category aircraft, with many ground infrastructure constraints. Both were recently equipped by the Hellenic air navigation service provider with RNP approaches. We successfully flight tested the satellite based augmentation to GPS landing system converter and show that both airports could benefit from a permanent installation of such a system by having fewer diversions.

Performance-Based Navigation Flight Path Analysis Using Fast-Time Simulation

Abstract: The growing demand for air transportation has led to an increase in worldwide air traffic inefficiency due to capacity constraints. The impacts associated with this situation can be reduced through operational changes. To better handle the problem, the Single European Sky ATM Research (SESAR) and the Next Generation Air Transportation System (NextGen) program suggest Performance-Based Navigation (PBN) as a solution. The Area Navigation (RNAV) and Required Navigation Performance (RNP) approaches belong to the group of PBN procedures. These procedures allow for a more efficient use of airspace by reducing route distances, fuel consumption and perceived aircraft noise. This article quantifies the benefits of PBN systems for two indicator parameters—fuel burn and flight time—and compares PBN systems to conventional instrument navigation procedures. The case studies use five airports in Brazil. The results of this analysis show that the benefits of the PBN approach vary with aircraft type and individual route characteristics.
