ICAO 9883 PDF

FOREWORD

This manual was produced by the ICAO Air Traffic Management (ATM) Requirements and Performance Panel within the context of a performance-based global air navigation system.

The notion of a performance-based air navigation system emanated from sound industry practices external to the aviation industry. As the aviation industry has evolved into a less regulated and more corporate environment, the advantages of implementing a performance-based air navigation system are becoming increasingly apparent.

The performance-based approach (PBA) is based on the following principles:

— strong focus on desired/required results through adoption of performance objectives and targets;

— informed decision-making, driven by the desired/required results; and

— reliance on facts and data for decision-making.

Assessment of achievements is periodically checked through performance reviews, which in turn requires adequate performance measurement and data collection capabilities

Establishing a PBA requires knowledge-sharing, training and other specific expertise.

The expected result is a more efficient system through identified cost savings, reduction in the waste of resources, more equitable charging practices, and more efficient provision of services. As the work effort is challenging and requires a globally coordinated effort, the aviation community should be encouraged to follow a common approach toward the development and implementation of a performance-based air navigation system.

The PBA can be applied in economic management, transition management, safety management, security management, communications, etc. This manual is not replacing any existing ICAO guidance material in these areas, rather it is to be seen as overarching and complementary guidance, introducing a set of performance management terminology and techniques to assist the aviation community members in converging towards a globally harmonized and agreed upon approach.

One of the objectives of this manual is to promote the use of harmonized terminology among ATM community members applying the performance-based approach in their area of interest. This terminology is introduced progressively, throughout the various chapters and sections of the document. Because some readers may not read the document in its entirety or in sequential order, they may experience difficulty locating certain terminology definitions. Consequently, an abbreviations and terminology list has been provided for quick-reference purposes in the preliminary pages of this manual.
