Present and Future of Air Navigation: PBN Operations and Supporting Technologies

The present work reviews the new concept of operation that will be soon implemented in SESAR and NextGen (January 2020) using new state-of-the-art technology mainly based on onboard avionics: data link equipment, broadcast and surveillance systems, and Global Navigation Satellite System (GNSS) area augmentation. One of the main improvements of Performance-Based Navigation (PBN) is the use of satellites and more precise and accurate onboard instruments than current standard avionics related to ground-based navigation aids (VOR, NDB, DME, etc.). Air navigation systems have been without mayor updates for nearly 40 years, when most Very High Frequency Omnidirectional Range (VOR) and Tactical Air Navigation (TACAN) systems were implemented worldwide in the civil and military fields, respectively. These standard navigation systems lack new required performance navigation and required big deal of maintenance, especially in redundant systems. Recently, the development of new and precise GNSS and communication systems has allowed their use on different scenarios: Instrumental Flight Rules (IFR) departures, initial and final approaches, etc. Additionally, in several international airports, Ground Based Augmentation System (GBAS) approaches have been already successfully tested and implemented. Related to GBAS, the Automatic Dependent Surveillance Broadcast (ADS-B) is a cooperative technology that enhances pilots and controllers’ situation awareness, since ADS-B broadcasts own and other aircraft position. Controller Pilot Data Link Communications (CPDLC) may be another key element of the PBN concept of operations (CONOPS), since it provides air–ground data communications for the air traffic control (ATC) service and the aircrew, reducing risks associated to human factor: poor speaking, radio congestion, message confusion, standardization, etc. The main goal of this review is to present the PBN concept and the potentially supporting Communication, Navigation and Surveillance (CNS) systems, in the context of the NextGen and SESAR Air Traffic Management (ATM) modernization programmes.

GNSS Navigation for Enabling More Efficient and Effective Air Traffic Management

Abstract Area navigation (RNAV) and other appropriate navigation specifications of the ICAO Performance Based Navigation concept represents a significant shift from conventional radio navigation to navigation primarily based on the Global Navigation Satellite System (GNSS), which is poised to become the primary, and potentially only, means of air navigation. Here we demonstrate that using RNAV to define routes in one airspace sector over Croatia can reduce the number of potential conflicts between aircraft and thereby increase flight efficiency. At the same time, this can reduce the costs associated with air traffic management, thereby increasing effectiveness.

EUROPEAN AIR TRAFFIC MANAGEMENT MASTER PLAN

Abstract. In the article the issue of prospects development of airspace and air traffic of Europe isconsidered. Main problems of the existed air navigation system have been reviewed. Some actions to beundertaken in Ukraine to improve its airspace indicators and increase the number of aircraft served by ATSunits have been proposed. A performance based navigation concept is used by authors as a method to solvethe problem. The concept is based on the principal of strict focus on desired results and well informeddecision making process. The structure of the Master Plan and its stepwise implementation in the Europeairspace is described. The methods proposed to follow the plan structure appropriately have been reviewed.The performance based navigation concept can serve a key point in researches aimed at finding efficientways to develop airspace and air traffic in Europe. The role and functions of ATS units within the frameworkof the performance based navigation concept are considered. In future more research of this issue will beconducted and new results will be published.
