Regulatory framework Implementation status and planning Analysis supporting the Network Impact Assessment 8.33kHz VCS NM implementation support 8.33VCS Implementation Support 11 Assessment Objective Evaluate the impact of local measures granting exemptions on the VHF spectrum availability As an individual (isolated) effect (State level) Global effect (EU level) Analyse the availability of frequency assignments in the future considering: The forecasted frequency demand for all States Other known constraints (e.g. frequency demand in non 8.33 States)
The Network Impact is defined by the probability of success in the process of allocating new frequency assignments, taking into account the forecasted demand. A limited Network Impact can be considered in the case in which the future frequency demand can be satisfied without significant delays. 8.33VCS Implementation Support 12 Data availability and assumptions Assessment is performed based on frequency assignment allocation data: $e Available in SAFIRE $d(DDMMYY)
VHF frequency Service Designated Operational Coverage (DOC) 8.33 planning (i.e. conversion or exemption) $es $ec $em For all states EU Member States (28+2) Non-EU Member States participating in SAFIRE Current frequency congestion & forecasted frequency demand For 25kHz assignments For 8.33kHz assignments In 3 separate areas (Area1, 2 and 3) based on current spectrum congestion 8.33VCS Implementation Support
13 Frequency demand forecast data The forecast of future demand is based on Analysis of past frequency demand evolution, Known planned developments of the ATM infrastructure as covered by the Network Operations Plan Validation and extrapolation of demand trends based on the current situation Agreed by the States
Specific distribution of the demand was considered depending on the geographical position Different trend Different demand Different ratio between 25kHz and 8.33kHz assignments demand* *Normally a 80%-20% ratio between 8.33kHz/25kHz assignments demand is considered for all services in Area 1&2, while a 20%-80% ratio is considered for Area 3. This is due to States in Area 3 not being covered by the VCS Regulation 8.33VCS Implementation Support 14 Methodology(ies) Based on frequency demand satisfaction over a period of years (up to
2036) Measured by assessing the rate of success in finding frequency assignments for the forecasted demand rate of success above 95% ct a p rate of success below 95% l im a b Glo Dependent on the number of shifts allowed Based on the number of frequencies available in a geographical location Analysing the contribution of a proposed exemption to the reduction of the number of frequency assignments available in a certain area Qualifying the impact based on the number of frequencies available at the geographical location where the loss takes place (i.e. a loss of 10 potential new assignments in a location where 100 frequencies are available has not the same impact as having a similar loss in a location where only 11 are available) for 2018 (conservative case: minimum conversions vs. maximum no of exemptions)
l dua i v i Ind act imp 8.33VCS Implementation Support 15 Frequency demand satisfaction Nominal potential implementation scenario
The forecasted frequency demand is satisfactory fulfilled (above 95% satisfaction rate) for Area 1 and 2 States A maximum of 2 frequency shifts are allowed in order to allocate a solution Until 2028 for Area 3 all the demand is satisfied above 95% 8.33VCS Implementation Support 16 Frequency Congestion - estimated for end of 2018 8.33VCS Implementation Support No. of available 8.33kHz channels based on an ACC 50NM radius/FL450 service 17 Example of exemption spectrum contribution for end 2018

time interval The satisfaction rate for the Area 3 is constantly below 95% and on a decreasing trend 8.33VCS Implementation Support 19 Frequency demand variations Nominal Frequency demand (0 shift) The satisfaction rate trend for the States in Area 1 is constantly below 95%
The satisfaction rate for the States in Area 2, while above 95% for the first 9 years of the assessment, decreases and remains below this threshold after 2027 The satisfaction rate for the Area 3 States is constantly below 95% and on a decreasing trend 8.33VCS Implementation Support 20 Frequency congestion evolution forecast Comparison of the 8.33kHz channel congestion in Europe Nominal potential implementation scenario in 2018 vs. 2025 with the forecasted demand added Note: the reduction of the frequency congestion in core Europe is due to most of the local measures granting exemptions being lifted. The increase in congestion in the East European States is due to
- the lack of complete planning information from Bulgaria, Greece, Cyprus, - numerous exemptions for State aircraft accommodation (e.g. Romania) - the demand in 25kHz assignments from the States not participating in 8.33 programme (e.g. Turkey) 8.33VCS Implementation Support 21 Frequency Congestion estimated end 2018 8.33VCS Implementation Support No. of available 8.33kHz channels based on an ACC 50NM radius/FL450 service 22 Frequency Congestion estimated 2025 8.33VCS Implementation Support No. of available 8.33kHz channels based on an ACC 50NM radius/FL450 service
