Tunnels in the Sky

Abstract: This article describes implementation of Required Navigation Performance (RNP), an approach tool for aircraft that can improve safety, minimize fuel burn and save money for airlines. To use RNP as an approach tool, an aircraft flies down a tightly contained “tunnel” in the sky using onboard equipment to maintain separation from other “tunnels.” The tool, in the making for 15 years, is in the process of being implemented at remote airports where there is less air traffic. It is more complicated to implement where air traffic is more dense and there is greater fleet mix. In addition, as it moves to areas around the world, there has been a proliferation of standards, and some airlines are uncertain whether their pilots are approved to be operating certain procedures. The article also describes its relationship to Area Navigation (RNAV).

GPS (Global Position System) RNP (Required Navigation Performance) flight program checking method

Abstract: The invention discloses a GPS (Global Position System) RNP (Required Navigation Performance) flight program checking method, belonging to the field of flight check. The flight program checking method comprises the steps: firstly, confirming a flight plan according to a flight checking task; then, inputting a waypoint code in a flight program to be checked to a checking system or a flight management system, and checking whether navigation data used in the designed flight program, the calculated distance between waypoints and direction data are correct in a cross checking way; next, forecasting the checked flight period and the GPS RAIM availability condition on a route to execute a flight mission by using a GPS RAIM (Receiver Autonomous Integrity Monitoring) availability forecasting tool; and finally, flying according to the design of the flight program, wherein the flight height is executed according to the minimum value designed by the flight program. The flight checking is finished according to the concrete checking items, and a checking report is generated. The method is designed according to the international civil aviation organization standard, meets relevant requirements and provides a reference method for checking the GPS RNP flight program.

The impact of advanced technology on Next Generation Air Transportation: A case study of Required Navigation Performance (RNP)

Abstract: This paper presents an overview and case studies of Performance -based System capability of Next Generation Aviation Transportation System (NGATS), specifically the case of Required Navigation Performance. The Required Navi gation Performance (RNP), one of the key capabilities of Performance -based system, defines lateral navigational precision level, which provides the opportunity to reduce fuel, negative environmental effect, airline operation disruptions, and to increase ru nway utilization and safety. In the early U.S. cases, airlines took a leading role in development of RNP, based on the strong economical motivation and clear business objectives. Reduction in diversions, cancellation, and fuel consumption translated int o significant cost saving and better service quality. There are also cases that RNP increased payload and runway utilization rate. Selective decision process to deploy RNP at the locations where most suitable, showed a great potential of Performance Base d Navigation, yet the implementation process was still limited by system provider ’s capability and the authorization process . In this paper, we will present three early RNP cases in US, including Alaska Airlines, Jetblue Airway, Continental Airlines, and discuss what RNP and Performance Based Navigation can truly deliver and how future development should be carried out.

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.

Preliminary two-dimensional area navigation terminal simulation

Abstract: : The simulation study analyzed selected controller workload and system performance measures for two route configurations representing two time frames and various percentage mixes of area navigation (RNAV) and non-RNAV operations, referred to in this report as participation levels. Results indicated that controllers could use RNAV maneuvers in the control of traffic in lieu of radar vector techniques and that controller workload decreased as the RNAV participation level increased. Controller acceptance of RNAV principles and techniques in terminal ATC increased as familiarity and experience with the various RNAV functions were gained. Subjective results pointed out that in order that RNAV be an effective tool within the terminal air traffic system, adequate training and a thorough familiarization with RNAV procedures, capabilities, and limitations would be a requirement for both controllers and pilots.
