ICAO CIRCULAR 335 PDF

FOREWORD

This circular provides a more detailed view of the air traffic management service delivery management (ATM SDM) component of the Global Air Traffic Management Operational Concept (GATMOC, Doc 9854) — a component that is of chief importance because of its coordinating role. Even if more detailed, this view is still at the same conceptual level as the GATMOC itself and hence an integral part of it. It is foreseen that the material in this circular will be incorporated into Doc 9854 in the future.

Readers may recall that the GATMOC is a "vision statement" — an ideal to be pursued through coordinated planning and implementation activities that are focused on satisfying the eleven ATM community expectations (otherwise known as the eleven key performance areas (KPAs)). KPAs are based on following the Manual on Global Performance of the Air Navigation System (Doc 9883) and are managed by the relevant national, regional and global plans.

The GATMOC is based on seven interdependent components, the operation of which should be integrated. However, ATM SDM plays a singular, coordinating role across the other components. Indeed, "The ATM service delivery management component will address the balance and consolidation of the decisions of the various other processes/ services, as well as the time horizon at which, and the conditions under which, these decisions are made" (GATMOC, 2.1.9).

Because of its vital importance, it became necessary to provide a more detailed view of ATM SDM, albeit a view that is still at the same conceptual level as the GATMOC.

The task was allocated to the Air Traffic Management Requirements and Performance Panel (ATMRPP), which continues the work of the Air Traffic Management Operational Concept Panel (ATMCP) that developed the GATMOC. This circular is the result of the work on expanding the concept of ATM SDM.
