Abstract

National libraries have recently adopted a quality assessment culture using performance indicators. The project for devising Technical Report ISO/TR 28118 regarding performance indicators for national libraries is explained from its beginnings. This is a specific common standard that permit benchmarking among similar institutions at the international level. The involvement of the international bodies IFLA, ISO and CENL in this initiative is described based on observation of the situations common to all national libraries. The technical process of drawing up the report is likewise described, along with its structure and contents. Also dealt with is the recent experience of the National Library of Spain in incorporating performance indicators to its evaluation processes and applying the ISO report indicators.

Abstract

Free Route Airspace is an operational concept for the modernization of the airspace, addressed to improving the efficiency of the flights. It also aims at the environmental friendly performance area by reducing the emissions from fuel burnt. But these benefits should not derive in a loss of safety. Several areas are introducing free route as part of the Single European Sky Airspace Research programme (SESAR). This paper assesses the Northern Europe Free Route Airspace deployment, where two SESAR solutions are combined: the Free Route Airspace and the Functional Airspace Blocks. This assessment is produced using fast-time simulations and presented from a safety perspective using two indicator sets: the aircraft loss of separation and the airspace complexity. The number of potential separation losses, together with complexity metrics, such as adjusted density, potential horizontal, vertical and/or speed interactions, are presented for different free route deployment status. Results reflect that from the safety perspective the free route deployment in North Europe did not present notable changes in terms of the selected indicators, despite of the increase of traffic of last years.
