(a) Except as provided in paragraph (b) of this section, this part prescribes rules governing— (1) The provision of air traffic services (ATS) in the Kingdom of Saudi Arabia (KSA) as well as in the airspace over the high seas encompassed by the Jeddah Flight Information Region (FIR) by an air traffic service provider that holds or is required to hold an Air Navigation Service Certificate (ANSC) under General Authority of Civil Aviation Regulation (GACAR) Part 170; (2) Each person employed or used by an ATS provider when providing ATS under this part; (3) The requirements for, and the contents of, an air traffic services procedure (ATSP) manual; (4) The designation, classification and registration of ATS airspace and UTM airspace including information for persons who wish to request a designation and classification of airspace; and (5) The establishment and registration of routes and minimum altitudes. Note: UTM airspace is not subject to classification. (b) This part does not apply to: (1) A person who is providing air traffic services to military aircraft in the course of his duties for the Saudi Arabian military; or (2) Any air traffic services provided to military aircraft by the Saudi Arabian military. (c) Additional requirements applicable to ATS providers are prescribed under General Authority of Civil Aviation Regulation (GACAR) Part 173. (d) Additional requirements applicable to the administering authority and user agencies of certain types of special use airspace are prescribed under General Authority of Civil Aviation Regulation (GACAR) Part 71. § 171.3 Restrictions on Air Traffic Services Providers. (a) No person may provide an air traffic service (ATS) in the Kingdom of Saudi Arabia unless the person complies with the provisions of this part and they have been certificated by the President under GACAR Part 170 to provide such service. (b) Each ATS provider must provide ATS within KSA airspace in accordance with the obligations imposed by the Convention on International Civil Aviation and Regional Air Navigation Agreements GACAR Part 171 Page 9 UNCONTROLLED DOCUMENT WHEN DOWNLOADED Consult the GACA website for current version VERSION 7.0 28 June 2026 GACA العربيه العالميه للطهاره المختار General Authority of Civil Aviation [Non-Text] GACAR PART 171 – AIR TRAFFIC SERVICES unless a difference has been notified to ICAO by the Kingdom of Saudi Arabia. (c) Except as provided in GACAR Part 170, each ATS provider must comply with the limitations and provisions of their certificate, operations specifications and their manual prepared under Subpart C. § 171.5 Objectives of Air Traffic Services. (a) The objectives of ATS must be to: (1) Prevent collisions between aircraft; (2) Prevent collisions between aircraft on the maneuvering area and obstructions on that area; (3) Expedite and maintain an orderly flow of air traffic; (4) Provide advice and information useful for the safe and efficient conduct of flights; and (5) Notify appropriate organizations regarding aircraft in need of search and rescue aid, and assist such organizations as required. (b) The objectives of the Air Traffic Control (ATC) services exclude prevention of collision with terrain except when controlled flights are being vectored by radar. Note - These provisions are general statements which represent high-level safety objectives to be met when providing Air Traffic Services. § 171.7 Divisions of Air Traffic Services. (a) The air traffic services must comprise three services identified as follows: (1) The air traffic control service, to accomplish objectives (a)(1), (a)(2) and (a)(3) of §171.5, this service being divided in three parts as follows: (i) Area control service: the provision of air traffic control service for controlled flights, except for those parts of such flights described in (a)(1)(ii) and (a)(1)(iii) of this section, in order to accomplish objectives (a)(1) and (a)(3) of §171.5. (ii) Approach control service: the provision of air traffic control service for those parts of controlled flights associated with arrival or departure, in order to accomplish objectives (a)(1) and (a)(3) of §171.5. (iii) Aerodrome control service: the provision of air traffic control service for aerodrome traffic, except for those parts of flights described in §171.7 (a)(1)(ii), in order to accomplish objectives (a)(1), (a)(2) and (a)(3) of §171.5.

(3) Alerting service to notify appropriate organizations regarding aircraft in need of search and rescue aid, and assist such organizations as required; and (b) Where air traffic services are established, the certified ATS provider must publish information as necessary to permit the utilization of such services. § 171.9 Determination of the Need for Air Traffic Services. (a) The need for the provision of ATS must be determined by the General Manager of Air Traffic Services (GM-ATS) as defined under GACAR Part 171, §171.43(a)(3), and must be accepted by the President. The factors that must be considered in determining the need for the provision of ATS include: (1) The types of air traffic involved; (2) The density of air traffic; (3) The meteorological conditions; (4) Such other factors as may be relevant. Note. — Due to the number of elements involved, it has not been possible to develop specific data to determine the need for air traffic services in a given area or at a given location. For example: (i) a mixture of different types of air traffic with aircraft of varying speeds (conventional jet, etc.) might necessitate the provision of air traffic services, whereas a relatively greater density of traffic where only one type of operation is involved would not; (ii) meteorological conditions might have considerable effect in areas where there is a constant flow of air traffic (e.g., scheduled traffic), whereas similar or worse meteorological conditions might be relatively unimportant in an area where air traffic would be discontinued in such conditions (e.g. local VFR flights); (iii) open stretches of water, mountainous, uninhabited or desert areas might necessitate the provision of air traffic services even though the frequency of operations is extremely low. (b) The carriage of airborne collision avoidance systems (ACAS) by aircraft in a given area must not be a factor in determining the need for ATS in that area. § 171.11 Designation of the Portions of the Airspace and Controlled Aerodromes Where Air Traffic Services Will be Provided. (a) When it has been determined that ATS will be provided in particular portions of the airspace or at particular aerodromes, then those portions of the airspace or those aerodromes must be designated in GACAR Part 171 Page 11 UNCONTROLLED DOCUMENT WHEN DOWNLOADED Consult the GACA website for current version VERSION 7.0 28 June 2026 GACA الطبيه العامه للطيران المضني General Authority of Civil Aviation GACAR PART 171 – AIR TRAFFIC SERVICES relation to the ATS that are to be provided. (b) The designation of the particular portions of the airspace or the particular aerodromes must be as follows: (1) Flight information regions (FIR). Those portions of the airspace where it is determined that flight information service and alerting service will be provided must be designated as Flight Information Regions (FIRs). (2) Control areas and control zones. (i) Those portions of the airspace where it is determined that air traffic control service will be provided to IFR flights must be designated as control areas or control zones. (ii) Those portions of controlled airspace wherein it is determined that air traffic control service will only be provided to IFR flights must be designated as Class A airspace. (iii) Those portions of controlled airspace wherein it is determined that air traffic control service will also be provided to VFR flights must be designated as Classes B, C, or D airspace. (iv) Where designated within a flight information region (FIR), control areas and control zones must form part of that FIR. (3) Controlled aerodromes. Those aerodromes where it is determined that air traffic control service will be provided to aerodrome traffic must be designated as controlled aerodromes. § 171.13 Establishment and Designation of the Units Providing Air Traffic Services. The air traffic services must be provided by units established and designated as follows: (a) Flight information centers (FIC) must be established to provide flight information service and alerting service within flight information regions, unless the responsibility of providing such services within a flight information region is assigned to an air traffic control unit having adequate facilities for the discharge of such responsibility. Note. — This does not preclude delegating to other units the function of providing certain elements of the flight information service. (b) Air traffic control units (ATCU) must be established to provide air traffic control service, flight information service and alerting service within control areas, control zones and at controlled aerodromes. (c) The following types of ATCU may be established to provide air traffic control services: GACAR Part 171 Page 12 UNCONTROLLED DOCUMENT WHEN DOWNLOADED Consult the GACA website for current version VERSION 7.0 28 June 2026 GACA العربيه العامه للطيران المدني General Authority of Civil Aviation GACAR PART 171 – AIR TRAFFIC SERVICES (1) Area Control Centers (ACC); (2) Approach Control Units (APP); and (3) Aerodrome Control Towers (TWR). (d) Where air traffic services are established, the certified ATS provider must publish information as necessary to permit the utilization of such services. § 171.15 Specifications for Flight Information Regions, Control Areas and Control Zones. (a) General. The delineation of airspace, wherein ATS are to be provided, must be related to the nature of the route structure and the need for efficient service rather than to national boundaries. Note 1. — Agreements to permit the delineation of airspace lying across national boundaries are necessary when such action will facilitate the provision of air traffic services. Agreements which permit delineation of airspace boundaries by straight lines will, for example, be most convenient where data processing techniques are used by air traffic services units. Note 2. — Where delineation of airspace is made by reference to national boundaries there is a need for suitably sited transfer points to be mutually agreed upon with ATS provider(s) in the adjacent States. (b) Flight information regions (FIRs). (1) Flight information regions must be delineated to cover the whole of the air route structure to be served by such regions. (2) A flight information region must include all airspace within its lateral limits, except as limited by an upper FIR. (3) Where a FIR is limited by an upper FIR, the lower limit specified for the upper FIR must constitute the upper vertical limit of the FIR and must coincide with a VFR cruising level as prescribed in GACAR § 91.169. (4) When an ATS provider proposes to re-organize the airspace, this re-organization must not affect the boundaries of Jeddah Flight Information Region and the proposed structure must limit the number of control areas. Each control area must be delineated to include an upper airspace within the lateral limits of Jeddah FIR and consider the lower limits of other or adjacent control areas. Note. — In cases where an upper flight information region is established the procedures applicable therein need not be identical with those applicable in the underlying flight information region. (c) Control areas.
