Princípios sob os acordos da ICAO
A delegação de serviços de ATC é contratada entre os membros da ICAO usando cartas de acordo bilaterais ou multilaterais. Casos de tal delegação existem tipicamente para cobrir grandes espaços aéreos remotos (por exemplo, acordo do Ártico entre vários países), ou pequenas áreas (por exemplo, ilhas).
Os membros da ICAO estão comprometidos em cumprir as decisões de seu ato constituinte, a Convenção de Chicago assinada em 1944 Entre os anexos da Convenção, o anexo 15 está relacionado à prestação de serviços de informação aeronáutica ( AIS):
Annex 15 defines how an aeronautical information service shall receive and/or originate, collate or assemble, edit, format, publish/store and distribute specified aeronautical information/data. The goal is to satisfy the need for uniformity and consistency in the provision of aeronautical information/data that is required for the operational use by international civil aviation.
Impacto no AIP
O Anexo 15 inclui estes artigos genéricos:
3.1.1.2 Each Contracting State shall take all necessary measures to ensure that the aeronautical information/data it provides relating to its own territory, as well as areas in which the State is responsible for air traffic services outside its territory, is adequate, of required quality and timely. This shall include arrangements for the timely provision of required information/data to the aeronautical information service by each of the State services associated with aircraft operations.
e
3.1.7 An aeronautical information service shall receive and/or originate, collate or assemble, edit, format, publish/store and distribute aeronautical information/data concerning the entire territory of the State as well as areas in which the State is responsible for air traffic services outside its territory. Aeronautical information shall be published as an Integrated Aeronautical Information Package.
Não consegui encontrar a decisão de usar o AIP ENR 2.2 (outro espaço aéreo regulamentado), mas, na verdade, a informação é encontrada aqui, por ex. na Noruega AIP :
5: Delegation of Responsibility for Provision of ATS
5.1: General Denmark, Norway, Sweden and the United Kingdom have arranged through the exchange of bilateral Letters of Agreement to transfer the responsibility for provision of ATS within parts of their own area of responsibility, to their neighbouring State.
Procedures and communication within the said areas will be as if the airspace was an integral part of the FIR for which the nation mentioned is responsible.
Escopo bidirecional
Um efeito desses artigos é tanto a delegação quanto os estados fornecedores publicam informações sobre áreas relacionadas. Por exemplo, no AIP espanhola , são descritos dois casos.
Espanha a delegar em Portugal:
By agreement between Sevilla ACC and Lisboa ACC, the air traffic service is provided by Lisboa ACC within the airspace defined by [...]
