This Civil Aviation Regulation was developed based on the Standards and Recommended Practices prescribed by the International Civil Aviation Organization (ICAO) as contained in Annex 15 which was first adopted by the Council on 15 May 1953 pursuant to the provisions of Article 37 of the Convention of International Civil Aviation (Chicago 1944), and consequently became applicable on 1 April 1954. Correspondingly, Article 38 of the Convention imposed an obligation to the CAAP to notify ICAO of any differences between its national regulations and practices and the International Standards contained in Annex 15 and any amendments thereto, especially when such differences are important for the safety of air navigation. Further, CAAP is encouraged to inform the ICAO of any differences which may subsequently occur, or of withdrawal of any differences previously notified.

Consequently, published aeronautical geographical coordinates (indicating latitude and longitude) shall be expressed in terms of the WGS-84 geodetic reference datum. Note.— Comprehensive guidance material concerning WGS-84 is contained in the World Geodetic System — 1984 (WGS-84) Manual (ICAO Document 9674). 15.1.2.1.2 In precise geodetic applications and some air navigation applications, temporal changes in the tectonic plate motion and tidal effects on the Earth’s crust should be modelled and estimated. To reflect the temporal effect, an epoch should be included with any set of absolute station coordinates. Note 1.— The epoch of the WGS-84 (G873) reference frame is 1997.0 while the epoch of the latest updated WGS-84 (G1150) reference frame, which includes a plate motion model, is 2001.0. (G indicates that the coordinates were obtained through Global Positioning System (GPS) techniques, and the number following G indicates the GPS week when these coordinates were implemented 2nd Edition 15.1-12 July 2023 CAR-ANS PART 15 in the United States’ National Geospatial- Intelligence Agency’s precise ephemeris estimation process.). Note 2.— The set of geodetic coordinates of globally distributed permanent GPS tracking stations for the most recent realization of the WGS-84 reference frame (WGS-84 (G1150)) is provided in ICAO Document 9674. For each permanent GPS tracking station, the accuracy of an individually estimated position in WGS-84 (G1150) has been in the order of 1 cm (1σ). Note 3.— Another precise worldwide terrestrial coordinate system is the International Earth Rotation Service (IERS) Terrestrial Reference System (ITRS), and the realization of ITRS is the IERS Terrestrial Reference Frame (ITRF). Guidance material regarding the ITRS is provided in Appendix C of ICAO Document 9674. The most current realization of the WGS-84 (G1150) is referenced to the ITRF 2000 epoch. The WGS-84 (G1150) is consistent with the ITRF 2000 and in practical realization the difference between these two systems is in the one to two centimeter range worldwide, meaning WGS-84 (G1150) and ITRF 2000 are essentially identical. 15.1.2.2 Vertical reference system 15.1.2.2.1 Mean sea level (MSL) datum shall be used as the vertical reference system for international air navigation. Note 1.— The geoid globally most closely approximates MSL. It is defined as the equipotential surface in the gravity field of the Earth which coincides with the undisturbed MSL extended continuously through the continents. Note 2.— Gravity-related heights (elevations) are also referred to as orthometric heights while distances of points above the ellipsoid are referred to as ellipsoidal heights. 15.1.2.2.2 The Earth Gravitational Model — (EGM-96) shall be used as the global gravity 1996 model for international air navigation. 15.1.2.2.3 At those geographical positions where the accuracy of EGM-96 does not meet the accuracy requirements for elevation and geoid undulation on the basis of EGM-96 data, regional, national or local geoid models containing high resolution (short wavelength) gravity field data shall be developed and used. When a geoid model other than the EGM-96 model is used, a description of the model used, including the parameters required for height transformation between the model and EGM-96, shall be provided in the Aeronautical Information Publication (AIP). Note.— Specifications concerning determination and reporting (accuracy of field work and data integrity) of elevation and geoid undulation at specific positions at aerodromes/heliports are given in the MOS AIS, Appendix 1.

Note 1.— A value in the time domain is a temporal position measured relative to a temporal reference system. Note 2.— Coordinated Universal Time (UTC) is a time scale maintained by the Bureau International de l’Heure (BIH) and the IERS and forms the basis of a coordinated dissemination of standard frequencies and time signals. Note 3.— See CAR-ANS Part 5, for guidance material relating to UTC. Note 4.— ISO Standard 8601 specifies the use of the Gregorian calendar and 24-hour local or UTC for information interchange while ISO Standard 19108 prescribes the Gregorian calendar and UTC as the primary temporal reference system for use with geographic information. 15.1.2.3.2 When a different temporal reference system is used for some applications, the feature catalogue, or the metadata associated with an application schema or a data set, as appropriate, shall include either a description of that system or a citation for a document that describes that temporal reference system.

Note 2.— Requirements for terrain and obstacle data collection surfaces are contained in the MOS-AIS, Appendix 8. 15.5.3.3.1 The coverage areas for terrain and obstacle data sets shall be specified as: — Area 1: the entire territory of the Philippines; — Area 2: within the vicinity of an aerodrome, subdivided as follows: — Area 2a: a rectangular area around a runway that comprises the runway strip plus any clearway that exists; Note.— See MOS for Aerodromes Chapter 6 for dimensions for runway strips. — Area 2b: an area extending from the ends of Area 2a in the direction of departure, with a length of 10 km and a splay of 15 per cent to each side; — Area 2c: an area extending outside Area 2a and Area 2b at a distance of not more than 10 km from the boundary 2nd Edition 15.5-4 July 2023 CAR-ANS PART 15 of Area 2a; and — Area 2d: an area outside Areas 2a, 2b and 2c up to a distance of 45 km from the aerodrome reference point, or to an existing terminal control area (TMA) boundary, whichever is nearest; — Area 3: the area bordering an aerodrome movement area that extends horizontally from the edge of a runway to 90 m from the runway center line and 50 m from the edge of all other parts of the aerodrome movement area; and — Area 4: the area extending 900 m prior to the runway threshold and 60 m each side of the extended runway center line in the direction of the approach on a precision approach runway, Category II or III. 15.5.3.3.2 Where the terrain at a distance greater than 900 m (3 000 ft) from the runway threshold is mountainous or otherwise significant, the length of Area 4 should be extended to a distance not exceeding 2 000 m (6 500 ft) from the runway threshold. 15.5.3.3.3 Terrain data sets 15.5.3.3.3.1 Terrain data sets shall contain the digital representation of the terrain surface in the form of continuous elevation values at all intersections (points) of a defined grid, referenced to common datum. 15.5.3.3.3.2 Terrain data shall be provided for Area 1. 15.5.3.3.3.3 For aerodromes regularly used by international civil aviation, terrain data shall be provided for: a) Area 2a; b) the take-off flight path area; and c) an area bounded by the lateral extent of the aerodrome obstacle limitation surfaces. 15.5.3.3.3.4 For aerodromes regularly used by international civil aviation, additional terrain data should be provided within Area 2 as follows: a) in the area extending to a 10-km radius from the ARP; and b) within the area between 10 km and the TMA boundary or a 45-km radius (whichever is smaller), where terrain penetrates a horizontal terrain data collection surface specified as 120 m above the lowest runway elevation. 15.5.3.3.3.5 Arrangements should be made for coordinating the provision of terrain data for adjacent aerodromes where their respective coverage areas overlap to assure that the data for the same terrain is correct. 15.5.3.3.3.6 For those aerodromes located near territorial boundaries, arrangements should be made among States concerned to share terrain data.
