((14)) ‘standard instrument arrival (STAR) route’ means a designated instrument flight rule arrival route linking a significant point, normally on an air traffic service (ATS) route, with a point at which a published instrument approach procedure can be commenced;
((15)) ‘standard instrument departure (SID) route’ means a designated instrument flight rule departure route linking the aerodrome with a specified significant point, normally on a designated ATS route, at which the en route phase of a flight commences;
((16)) ‘navigation functionality’ means the detailed capability of the navigation system required to meet the needs of the proposed operations in the airspace.
Article 3 
Providers of ATM/ANS shall comply with the requirements for the implementation of performance-based navigation set out in Subpart PBN of the Annex.
Article 4 

1. Providers of ATM/ANS shall take the necessary measures to ensure a smooth and safe transition to the provision of their services using performance-based navigation in accordance with Article 3.Those measures shall include the establishment and implementation of a transition plan. Providers of ATM/ANS shall keep their transition plan up-to-date.The transition plan shall be consistent with  any regulations made by the Secretary of State under Article 15a of Regulation 550/2004  of the European Parliament and of the Council.
2. Providers of ATM/ANS shall consult all of the following parties on the draft transition plan and the draft of any significant updates thereof and take account of their views where appropriate:
(a) aerodrome operators, airspace users and representative organisations of such airspace users affected by the provision of their services;
(b) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
(c) providers of ATM/ANS that provide their services in adjacent airspace blocks.
3. After having carried out the consultation referred to in paragraph 2, providers of ATM/ANS shall submit the results of the consultation, as well as the draft transition plan, or the draft significant update thereof, for approval to the  Civil Aviation Authority.The Civil Aviation Authority  shall verify whether the draft transition plan, or the draft significant update thereof, complies with the requirements of this Regulation and in particular whether it takes account of the views of airspace users where appropriate, including those operating State aircraft. ...The Civil Aviation Authority  shall inform the providers of ATM/ANS of the outcome of that verification without undue delay. Providers of ATM/ANS shall not establish or implement the transition plan, or the significant update thereof, before having been informed by  the Civil Aviation Authority  that it has approved the draft transition plan or draft significant update thereof.
Article 5 

1. Providers of ATM/ANS shall not provide their services using conventional navigation procedures, or using performance-based navigation which is not in accordance with the requirements of point AUR.PBN.2005 of the Annex.
2. Paragraph 1 shall be without prejudice to Article 6 and to the possibility of providers of ATM/ANS to provide their services using landing systems enabling CAT II, CAT IIIA or CAT IIIB operations within the meaning of points 14, 15 and 16, respectively, of Annex I to Regulation (EU) No 965/2012.
Article 6 
Providers of ATM/ANS shall take the necessary measures to ensure that they remain capable of providing their services through other means where, for unexpected reasons beyond their control, GNSS or other methods used for performance-based navigation are no longer available, making it impossible for them to provide their services in accordance with Article 3. Those measures shall include, in particular, retaining a network of conventional navigation aids and related surveillance and communications infrastructure.

ANNEX
AUR.PBN.1005 
In accordance with Article 3, this Subpart sets out the requirements for the implementation of performance-based navigation (PBN) to be complied with by providers of ATM/ANS.

AUR.PBN.2005  (1) Providers of ATM/ANS shall implement, at all instrument runway ends,  other than for aerodromes listed in point 1.2.1 of the Annex to Implementing Regulation (EU) No 716/2014 and instrument runway ends served by precision approach procedures at other aerodromes, approach procedures in accordance with the requirements of the RNP approach (RNP APCH) specification, including LNAV, LNAV/VNAV and LPV minima and, where required due to traffic density or traffic complexity, radius to fix (RF) legs.
 (2) By way of derogation from point (1), at instrument runway ends where, due to terrain, obstacles or air traffic separation conditions, the implementation of 3D approach procedures is excessively difficult, providers of ATM/ANS shall implement 2D approach procedures in accordance with the requirements of the RNP approach (RNP APCH) specification. In that case, they may also, in addition to the implementation of those 2D approach procedures, implement 3D approach procedures in accordance with the requirements of the RNP authorisation required (RNP AR APCH) specification.
 (3) By way of derogation from point (1) at instrument runway ends without an appropriate SBAS coverage, providers of ATM/ANS shall implement RNP APCH procedures, including LNAV and LNAV/VNAV minima. Providers of ATM/ANS shall also implement LPV minima at those instrument runway ends, no later than 18 months from the date at which such appropriate SBAS coverage is available.
 (4) ...
 (5)  (6) Where providers of ATM/ANS have established ATS routes for en route operations, for ATS routes at or above FL150,  they shall implement those routes in accordance with the requirements of the RNAV 5 specification.
 (7) By way of derogation from  point (6), where providers of ATM/ANS have established ATS routes, SID routes or STAR routes for rotorcraft operations, they shall implement those routes in accordance with the requirements of the RNP 0.3, RNAV 1 or RNP 1 specifications. In that case, they shall be entitled to decide which of those three sets of requirements they comply with.
