PLAN


• As an interface country between ECAC and AFI Regions, TUNISIA isasked to follow the European Navigation Strategy and regional implementation plans (CNS/ATM and GNSS Implementation)

INTERNATIONAL COOPERATION• Signed Agreements

• July 1997 : Tunisia – Italy• June 1998 : Tunisia – France• September 1998 : Tunisia – EUROCONTROL• April 2003 : Tunisia – ESA

• Ongoing projects • EUROMED : The EuroMed Transport Project aims to facilitate

cooperation between the 12 Mediterranean Partner Countries with the goal of supporting the development of the future Euro-Mediterranean Free Trade Area and promoting regional economic integration.

• BLUE MED : The BLUE MED project is pursuing the implementation of a Functional Airspace Block (FAB) in the South– East Mediterranean Area, in accordance with the requirements of the Single European Sky, to be put in operation within 2012 and with 2015 as target date for full FAB operations


• All the reporting points of the Tunisian airports have been surveyed in WGS-84 referential in accordance to the specifications of ICAO Doc 9674.

• The agreement on the Reporting Points located on the FIR limits has been coordinated with the edging FIRs.

IMPLEMENTATION OF THE WGS 84 REFERENTIAL


• The use of GNSS in Tunisian airspace is currently based on GPS only,

• The use of GPS is ruled by the decision of the minister of transport n° 574 dated on the 4th of November 2004,

TUNISIA TODAY :GNSS BASED ON GPS


• FIRST STAGE– JANUARY 2004 : (AIC NR 07/03) TUNISIAN

AIRSPACE IS B-RNAV (FL 245 AND ABOVE)• SECOND STAGE

– JANUARY 2006 : (AIC NR 12/05) TUNISIAN AIRSPACE IS B-RNAV (FL 155 AND ABOVE) ONLY IN AIRSPACES 2,3 AND 4

• THIRD STAGE– PLAN FOR THE INTRODUCTION OF PBN.

THE DRAFT NATIONAL PLAN IS ALREADY ESTABLISHED, THE FINAL DRAFT WILL BE ACHIEVED BY THE END OF 2009.

RNAV STATUS IN TUNISIA

• B-RNAV based on :• VOR/DME• DME/DME• GPS


GPS Procedures for Tunisian Airports designed in conformance with ICAO criteria (Doc 8186) and optimized after flight check have been published in AIRAC on December 2000.

Airport Number and type of procedure Implementation date


Tunisia is a hosting entity of a RIMS station installed in Djerba airport since 2003.

Djerba RIMS is the first operational station out the European region.

OACA is providing facility and assuming local maintenance activities of Djerba RIMS.

TUNISIA EVOLVING IN EGNOS PROJECT


TUNISIA EVOLVING IN EGNOS PROJECT

TUNISIA has expressed its intention to :

• Verify the navigation performances over selected areas and airports in Tunisia,

• Evaluate critical issues (telecommunication network, expansion mode, airborne receivers performances,…)

• Validate the EGNOS simulation model outside Europe,• Evaluate APV1 procedure design, constraints and

operations• Sensitise potential services providers and users,


CONCLUSION

• As an interface country Tunisia is called to follow the technical enhancement in the field of the air navigation and the implementation of GNSS.

• Success conditions of GNSS implementation:very wide international and regional cooperation and the adhesion of all partners (countries, organisations, air space agencies, regional work groups…).
