ICAO 9426 PDF

PURPOSE AND SCOPE

The manual not only contains information which can, or should, be taken into account in the formulation of development programmes within States or regions, but also material which can, or should, be applied directly to the planning and operation of the ATS system.

To this extent, the manual consists of the guidance material previously contained in various attachments to Annex 11 - Air Traffic Services and the Procedures for Air Navigation Services - Rules of the Air and Air Traffic Services (PANS-RAC, Doc 4444), updated as necessary to reflect latest developments, and also new material concerning important aspects of ATS planning which had not been covered until now. Such new material has, for the greater part, been extracted from various sources; however, this was done only once it had been established that the material was of general interest and that its application was not limited to specific circumstances only.

The material in this manual is intended to supplement the provisions governing ATS as specified in Annexes 2 and 11 and the PANS-RAC and it should therefore be used in conjunction with these documents. As a consequence, provisions contained in these documents are not reiterated in this manual but, where found useful, have been expanded to indicate their most practical application.
