Description

The need for practical application of air navigation services and facilities and their co-ordinated implementation in specific areas where operating conditions and other relevant parameters were comparable lead to the decision to sub-divide the surface of the earth into a number of "regions" within which distinct and specific air navigation problems of a similar nature existed.

For each of those regions, Regional Supplementary Procedures (SUPPS) are developed and published in ICAO Doc 7030: Regional Supplementary Procedures. These Procedures must not be in conflict with the provisions contained in the ICAO Annexes or PANS.

The SUPPS do not have the same status as SARPS. The latter are recommended to Contracting States for worldwide use, whilst the former are recommended to Contracting States for application in the groups of flight information regions to which they are relevant.
