Definitions
Article 2
For the purposes of this Regulation, the following definitions shall apply: (1) ‘performance based navigation (PBN)’ means performance based navigation as defined in Article 2(5) of Regulation (EU) No 965/2012; (2) ‘ATS route’ means ATS route as defined in Article 2(46) of Implementing Regulation (EU) No 923/2012; (3) ‘instrument approach procedure’ means instrument approach procedure as defined in Article 2(90) of Implementing Regulation (EU) No 923/2012; (4) ‘conventional navigation procedures’ means ATS routes and instrument approach procedures predicated on the use of ground-based navigation aids that do not enable compliance with the PBN requirements set out in this Regulation; (5) ‘instrument runway’ means instrument runway as defined in Annex I, point 22 of Commission Regulation (EU) No 139/2014 ( 11 ) ; (6) ‘navigation specification’ means a set of requirements for aircraft and aircrew needed to support performance-based navigation operations within a defined airspace; (7) ‘required navigation performance (RNP) X specification’ means a navigation specification based on area navigation that includes the requirement for on-board performance monitoring and alerting, whereby ‘X’ refers to the lateral navigation accuracy in nautical miles or the operation type and required functionalities; (8) ‘lateral navigation (LNAV)’, ‘lateral navigation/vertical navigation (LNAV/VNAV)’ and ‘localizer performance with vertical guidance (LPV)’ mean the labels to identify the different types of operating minima on approach charts depicting approach procedures based on Global Navigation Satellite Systems (GNSS) which are classified as RNP approaches (RNP APCH); (9) ‘radius to fix (RF)’ means a constant radius circular path about a defined turn centre that terminates at a fixed point; (10) ‘2D approach’ means an instrument approach procedure, classified as an non-precision approach procedure, as defined in Article 2(90) of Implementing Regulation (EU) No 923/2012; (11) ‘3D approach’ means an instrument approach procedure, classified as an approach with vertical guidance or a precision approach, as defined in Article 2(90) of Implementing Regulation (EU) No 923/2012; (12) ‘satellite-based augmentation system (SBAS)’ means a wide-coverage augmentation system in which the user of a GNSS receives augmentation information from a satellite-based transmitter; (13) ‘area navigation (RNAV) X specification’ means a navigation specification based on area navigation that does not include the requirement for on-board performance monitoring and alerting, whereby ‘X’ refers to the lateral navigation accuracy in nautical miles; (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.
