In 1995 Estonia became a full member of the European Civil Aviation Conference ECAC and expressed the intention to integrate and harmonise national ATC system with European Air Traffic Management. For achieving this target Estonia participates in the realisation of Convergence and Implementation Plan (CIP) coordinated by EUROCONTROL. This action plan covers entire European air traffic management network and it is reviewed regularly in order to  monitor the implementation status  and progress. CIP document is prepared for the period of five years; it is updated annually.

In the year 2009 the CIP document changed its name to Single Sky Implementation document.  There are two types of SSIP document: European Single Sky Implementation (ESSIP) and Local Single Sky Implementation (LSSIP).

The European document provides basic information needed by the States, Military Authorities and other aviation stakeholders to define and plan their own local implementation actions and to detail these in Local SSIP Documents.

The Local SSIP Documents set out national medium term plans and implementation activities required for the implementation of ESSIP  objectives. As such, they reflect the intent of each national stakeholder to contribute  to these plans and take agreed actions in achieving  ATM Performance Targets.

According to their scope there are three types of Implementation Objectives:

• ECAC or Pan-European – to be applied in all ECAC States within a specified common timescale
• EU+  –  to be applied in the Member States of the European Union , plus Norway and Switzerland
• Multi-N or MN ‘Multi-N’ – Multi-National - to be applied in some ECAC States
• Harmonisation – an extra objective to be applied by Individual States or at ATC unit level where the State concerned chooses to apply the objective to meet its local ATM Performance Targets

The four major national stakeholders - Estonian ANS, Estonian Civil Aviation Administration, Tallinn Airport and Estonian Air Force - are appointed by the State to develop LSSIP objectives.

The Estonian SSIP document for 2010-2014 covers the following areas:

• Airspace Organisation and Management (AOM)
• Airports Operations (AOP)
• Air Traffic Control (ATC)
• Communications & Spectrum Management (COM/SPC)
• Environment (ENV)
• Flow and Capacity Management Objectives (FCM)
• Human Factors  (HUM)
• Interoperability (ITY)
• Aeronautical Information Management (INF)
• Navigation (NAV)
• Safety Management (SAF)
• Surveillance (SUR)

The main implementation objectives for Estonia in 2010-2014 are:

Pan-European objectives:

·      Apply a common flight message transfer protocol (FMTP). December 2011.

·      Migrate from AFTN/CIDIN to AMHS for international communications. December 2011.

·      Implement enhanced tactical flow management services. December 2011.

·      Implement collaborative flight planning. December 2011.

·      Implement measures to prevent air/ground communications induced safety occurrences. January 2010.

·         Develop, facilitate and implement a `Just Culture' environment for supporting incident reporting and data sharing in ATM.

Multi-national objectives:

• Implement Advanced Surface Movement Guidance and Control System (A-SMGCS) Level I and II.  October 2010
• Rationalise the navigation infrastructure. December 2015
• Implement Continuous Descent Approach (CDA) techniques for environmental improvements. December 2013
• Implement measures to reduce the risk to aircraft operations caused by airspace infringements. December 2011.

Harmonisation objectives:

• Implementation of Precision Area Navigation RNAV. December 2012
