EANPG

• Endorsed assembly resolution A36-27 related to the provision of resources

• EANPG Conclusion 51/6 – Preparation for WRC-12– That the ICAO Regional Director, Europe and North Atlantic:

• a) urge States to:– i) ensure, via their National Telecommunication Agencies, that the ICAO position is taken

into account in the national and regional preparatory activities for World Radiocommunication Conference 2012 (WRC-12) ; and

– ii) provide civil aviation experts to assist in various national and regional WRC-12 preparatory activities.

• b) invite International Organisations (IATA, NATO, EC, ECAC, EUROCONTROL) and other organisations to ensure coherence with the ICAO position and support ICAO during various regional WRC-12 preparatory activities

• EANPG Conclusion 51/7 – ICAO EUR/NAT Support to WRC-12 Preparation– That the ICAO Regional Director, Europe and North Atlantic, make necessary

arrangements to ensure the participation of the EUR/NAT Office in the regional WRC-12 preparatory activities at the level of the Conférence Européenne des Administrations des Postes et des Télécommunications (CEPT) Conference Preparatory Group (CPG).

Other Issues: EANPG

• EANPG Conclusion 52/25 - Addressing aeronautical frequency spectrum congestion– That the ICAO Regional Director, Europe and North Atlantic:

• recognising the progress and applicability area of the currently being reviewed European Commission (EC) Regulation 1265/2007 on Air-Ground Voice Channel Spacing (A-VCS), urge States to proceed with the full implementation of 8.33 kHz channel spacing by 2018 with an intermediate phase by 2014;

• recognising the continued congestion in the aeronautical VHF voice band in the European Region, initiate development of the future operational requirements for VHF voice communications with the goal to reorient the ICAO work on future communication systems in order to address the future operational needs with regards to aeronautical VHF voice communications; and

• remind States to adhere to the provisions of the ICAO EUR Air Navigation Plan with regards to the gradual removal of VORs and NDBs from service by 2020.

Note 1 Additional HF allocations and data link implementation is anticipated to gradually reduce congestion (NAT Region)Note 2 With gradual removal of VORs the congestion is anticipated to ease.However, implementation and associated transition period for the deployement of future comm systems will exacerbate congestionNote 3 Under assumption that 8.33 kHz is not implemented below FL195. In the long run there is a need to speed up the roll out of future comm systems to carry digital voiceNote 4 Growing number of SSRs, implementation of Mode-S, ADS-B, MLAT increases the spectrum useNote 5 Problems in getting more access due to non aviation users operating in the bandNote 6 Congestion will grow with implementation of future AMRS and UAS in the band

EUR Frequency planning and coordination tools

• The planning and coordination process is supported by the following tools(provided by Eurocontrol upon EANPG request for all EUR):

– MANIF – voluntary for planning

– SAFIRE – mandatory means for coordination in the EUR for VHF assignments

• Transition for navaids assignments to SAFIRE is ongoing

• The outcome of this coordination is registered in the EUR central ICAO register, Supplement Tables COM2. 3 and 4 of the ICAO EUR Air Navigation Plan.

• Currently coordination of navaids assignment requests is done via AFTN/e-mail/fax using dedicated templates and the outcome is registered in the ODETE database
