            COMMISSION IMPLEMENTING REGULATION (EU) 2020/469
of 14 February 2020
         
amending Regulation (EU) No 923/2012, Regulation (EU) No 139/2014 and Regulation (EU) 2017/373 as regards requirements for air traffic management/air navigation services, design of airspace structures and data quality, runway safety and repealing Regulation (EC) No 73/2010
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EU) 2018/1139 of the European Parliament and of the Council of 4 July 2018 on common rules in the field of civil aviation and establishing a European Union Aviation Safety Agency, and amending Regulations (EC) No 2111/2005, (EC) No 1008/2008, (EU) No 996/2010, (EU) No 376/2014 and Directives 2014/30/EU and 2014/53/EU of the European Parliament and of the Council, and repealing Regulations (EC) No 552/2004 and (EC) No 216/2008 of the European Parliament and of the Council and Council Regulation (EEC) No 3922/91 (1), and in particular points (c) and (g) of Article 36(1), points (a) and (f) of Article 43(1) and Article 44(1) thereof,

Whereas:







(1)


Commission Regulation (EU) No 923/2012 (2) lays down the common rules of the air and operational provisions regarding services and procedures in air navigation applicable to general air traffic (the so called ‘rules of the air’).












(2)


Commission Regulation (EU) No 139/2014 (3) lays down requirements and administrative procedures related to aerodromes, including their management, operation, certification and oversight.












(3)


Commission Regulation (EU) 2017/373 (4) lays down common requirements for providers of air traffic management/air navigation services (‘ATM/ANS’) and other air traffic management network functions (‘ATM network functions’) for general air traffic and their oversight.












(4)


In order to ensure a high level of civil aviation safety in the Union, flight crews should be required to report to the air traffic service units, when the runway braking action they encounter is not as good as reported to them. Those reporting obligations should be set out in Implementing Regulation (EU) No 923/2012.












(5)


On 31 March 2016 the International Civil Aviation Organisation (‘the ICAO’) adopted Amendment 77-A to Annex 3 to the Convention on International Civil Aviation, signed on 7 December 1944 in Chicago (the ‘Chicago Convention’) aiming at improving the provision of information on hazardous meteorological conditions, enhancing situational awareness and contributing to a more efficient routing, including circumvention of hazardous meteorological conditions. That amendment is applicable in ICAO Contracting States as of 10 November 2016 and it should be reflected in Regulation (EU) 2017/373, in particular in the provisions on meteorological services (Annex V – Part-MET).












(6)


Regulation (EU) 2017/373 should reflect the state of the art in aviation safety, as well as best practices and scientific and technical progress in aeronautical information services (‘AIS’). Therefore, amendments to Regulation (EU) 2017/373 should be based on the applicable ICAO Standards and recommended practices (‘SARPs’), in particular on the Sixteenth Edition of Annex 15 ‘Aeronautical Information Services’ to the Chicago Convention, while drawing on the experience of the Union in AIS provision and ensuring proportionality according to the size, type and complexity of the AIS provider (‘AISP’).












(7)


On 31 March 2016 ICAO adopted also Amendment 77-B to Annex 3 to the Chicago Convention which aims at reducing runway excursion incidents and accidents. That Amendment 77-B to Annex 3 will be applicable in the ICAO Contracting States as of 5 November 2020. That amendment should also be reflected in Regulation (EU) 2017/373, in particular in the requirements laid down in Annex V as regards the provision of meteorological services and in Annex VI as regards the provision of aeronautical information services.












(8)


Pilots should be informed through notices to airmen when a runway is temporarily unavailable due to marking works. In order to increase runway safety, pilots intending to operate on a specially prepared winter runway or on a slippery wet runway should be appropriately informed. The dissemination of friction measurements to pilots should not be allowed because friction measurements are not correlated with aeroplane performance.












(9)


Common technical rules for the design of airspace structures as well as common requirements for service providers of flight procedure design (‘FPD’) should be established in Regulation (EU) 2017/373 to ensure that the airspace structures and flight procedures are properly designed, surveyed and validated before they can be deployed and used by aircraft.












(10)


Flight procedures and any changes thereto can affect the safety of flight operations at the aerodrome. Consequently, a clear link between the existing Regulation (EU) No 139/2014 and Regulation (EU) 2017/373 should be introduced.












(11)


With the adoption of the Seventh Edition of Annex 10 to the Chicago Convention on ‘Aeronautical Telecommunications’ (Volume II) published in July 2016, the Fifteenth Edition of Annex 11 to the Chicago Convention on ‘Air Traffic Services’ and the Sixteenth Edition of Doc 4444 ‘Procedures for Air Navigation Services – Air Traffic Management (PANS ATM)’, the ICAO adopted new ICAO SARPs on aviation safety in the provision of air traffic services (‘ATS’).












(12)


For those reasons, and in order to ensure the uniform implementation and compliance with the essential requirements set out in point 2.3 of Annex VIII to Regulation (EU) 2018/1139, Regulation (EU) 2017/373 should be amended accordingly.












(13)


Regulation (EU) No 923/2012 and Regulation (EU) 2017/373 should also include detailed provisions with regard to the availability and the conditions for the use of the Very-high frequency (VHF) emergency channel.












(14)


Additionally, taking into account the impact of ATM/ANS on pilot actions and aerodrome operations, those new measures should also be reflected in the relevant provisions of Regulation (EU) No 923/2012.












(15)


Those new measures include also detailed provisions on the quality of aeronautical data and aeronautical information and therefore Regulation (EU) No 73/2010 (5) should be repealed.












(16)


The industry and the competent authorities of the Мember States should be given sufficient time to adapt to the measures introduced by this Regulation.












(17)


The measures provided for in this Regulation are based on Opinion, 02/2018, Opinion 03/2018 and Opinion 03/2019 of the European Union Aviation Safety Agency in accordance with point (b) and (c) of Article 75(2) and Article 76(1) of Regulation (EU) 2018/1139.












(18)


The measures provided for in this Regulation are in accordance with the opinion of the committee established by Article 127 of Regulation (EU) 2018/1139.

‘Appendix 1

AERONAUTICAL DATA CATALOGUE


Introduction







(a)


The aeronautical data catalogue is a reference to the aeronautical data subjects, properties and sub-properties organised in:






(1)


aerodrome data;










(2)


airspace data;










(3)


ATS and other routes data;










(4)


instrument flight procedure data;










(5)


radio navigation aids/systems data;










(6)


obstacle data;










(7)


geographical position data.














(b)


The tables of the aeronautical data catalogue are composed of the following columns:






(1)


subject for which data can be collected;










(2)


property: an identifiable characteristic of a subject which may be further defined into sub-properties;










(3)


same as 2;










(4)


types: the data is classified into different types;










(5)


description: a description of the data item;










(6)


notes: containing additional information or conditions for the provision of the data;










(7)


accuracy: requirements for aeronautical data are based on a 95 % confidence level;










(8)


integrity classification;










(9)


origination type: data is identified as surveyed, calculated or declared;










(10)


publication resolution;










(11)


chart resolution.









Note for items 2 and 3 under point (b): the classification of a catalogue element as subject, property or sub-property does not impose a certain data model.


Note for item 7 under point (b): for those fixes and points that serve a dual purpose, e.g. holding point and missed approach point, the higher accuracy applies. Accuracy requirements for obstacle and terrain data are based on a 90 % confidence level.


Note for item 10 under point (b): the publication resolutions for geographical position data (latitude and longitude) are applicable to coordinates formatted in degrees, minutes, seconds. When a different format is used (such as degrees with decimals for digital data sets) or when the location is significantly further to the north/south, the publication resolution needs to be commensurate with the accuracy requirements.

Control areas shall be delineated so as to encompass sufficient airspace to contain the flight paths of those instrument flight rules (IFR) flights or portions thereof to which the applicable parts of the air traffic control (ATC) service are provided, taking into account the capabilities of the navigation aids normally used in that area.










(2)


A lower limit of a control area shall be established at a height above the ground or water of not less than 200 m (700 ft), unless otherwise prescribed by the competent authority.










(3)


An upper limit of a control area shall be established when either:






(i)


ATC service will not be provided above such upper limit; or










(ii)


the control area is situated below an upper control area, in which case, the upper limit shall coincide with the lower limit of the upper control area.


















(c)


CONTROL ZONES






(1)


The horizontal limits of a control zone shall encompass at least those portions of the airspace, which are not within control areas that contain the paths of IFR flights arriving at and departing from aerodromes to be used under instrument meteorological conditions (IMC).










(2)


If located within the horizontal limits of a control area, the control zone shall extend upwards from the surface of the earth to at least the lower limit of the control area.














(d)


FLIGHT INFORMATION ZONES






(1)


The horizontal limits of a flight information zone shall encompass at least those portions of the airspace, which are neither within control areas nor within control zone, that contain the paths of IFR and/or VFR flights arriving at and departing from aerodromes.










(2)


If located within the horizontal limits of a control area, the flight information zone shall extend upwards from the surface of the earth to at least the lower limit of the control area.









SECTION II


Identification of ATS routes other than standard departure and arrival routes







(a)


When ATS routes are established, a protected airspace along each ATS route and a safe spacing between adjacent ATS routes shall be provided.










(b)


ATS routes shall be identified through designators.










(c)


When identifying ATS routes other than standard departure and arrival routes, the designation system used shall:






(1)


permit the identification of any ATS route in a simple and unique manner;










(2)


avoid redundancy;










(3)


be usable by both ground and airborne automation systems;










(4)


permit utmost brevity in operational use; and










(5)


provide for a sufficient possibility of extension to cater for any future requirements without the need for fundamental changes;














(d)


Basic ATS route designators shall be assigned in accordance with the following principles:






(1)


the same basic designator shall be assigned to a main trunk route throughout its entire length, irrespective of terminal control areas, States or regions traversed;










(2)


where two or more trunk routes have a common segment, the segment in question shall be assigned each of the designators of the routes concerned, except where this would introduce difficulties in the provision of air traffic services (ATS), in which case, by common agreement, one designator only shall be assigned; and










(3)


a basic designator assigned to one route shall not be assigned to any other route.









SECTION III


Identification of standard departure and standard arrival routes and associated procedures







(a)


When identifying standard departure and standard arrival routes and associated procedures, it shall be ensured that:






(1)


the system of designators shall permit the identification of each route in a simple and unambiguous manner;










(2)


each route shall be identified by a plain language designator and a corresponding coded designator; and










(3)


in voice communications, the designators shall be easily recognisable as relating to a standard departure or standard arrival route and shall not create any difficulties in pronunciation for pilots and ATS personnel.














(b)


When composing designators for standard departure and standard arrival routes and associated procedures, the following shall be used:






(1)


a plain language designator;










(2)


a basic indicator;










(3)


a validity indicator that shall be a number from 1 to 9;










(4)


a route indicator that shall be one letter of the alphabet; the letters ‘I’ and ‘O’ shall not be used; and










(5)


a coded designator of a standard departure or standard arrival route, instrument or visual.














(c)


Assignment of designators






(1)


Each route shall be assigned a separate designator.










(2)


To distinguish between two or more routes that relate to the same significant point (and are therefore assigned the same basic indicator), a separate route indicator as described in point (b)(4) shall be assigned to each route.














(d)


Assignment of validity indicators






(1)


A validity indicator shall be assigned to each route to identify the route that is currently in effect.










(2)


The first validity indicator to be assigned shall be the number ‘1’.










(3)


Whenever a route is amended, a new validity indicator, which consists of the next higher number, shall be assigned. The number ‘9’ shall be followed by the number ‘1’.









SECTION IV


Establishment and identification of significant points







(a)


Significant points shall be established for the purpose of defining an ATS route or flight procedure and/or in relation to the ATS requirements for information on the progress of aircraft in flight.










(b)


Significant points shall be identified by designators.





SECTION V


Minimum flight altitudes

Minimum flight altitudes shall be determined for each ATS route and control area and shall be provided for promulgation. These minimum flight altitudes shall provide a minimum obstacle clearance within the areas concerned.

SECTION VI


Identification and delineation of prohibited, restricted and danger areas

When prohibited areas, restricted areas or danger areas are established, upon initial establishment, they shall be given an identification, and full details shall be provided for promulgation.
