2.1.10 Runways Used for Special Authorisation Category I instrument Approach Operations
Note: Special Authorisation Category I instrument approach operation is defined in AIP.
2.1.10.1 A runway is not suitable to be used for a Special Authorisation (SA) Category I instrument approach operation unless all of the requirements in paragraphs 2.1.10.2 to 2.1.10.10 are met.
2.1.10.2 The aerodrome at which the runway is located must be a controlled aerodrome.
Note: Aircraft operators will not be permitted to conduct SA Category I instrument approach operations unless aerodrome control is in operation.
2.1.10.3 Subject to paragraph 2.1.10.11, the runway must meet the standards in this MOS for a precision approach runway.
2.1.10.4 The runway must have electronic RVR equipment in the touchdown zone of the runway.
Note: The runway may have electronic RVR equipment in the other zones of the runway.
2.1.10.5 The aerodrome operator must confirm with the ATS provider that the control tower has suitable RVR display equipment.
2.1.10.6 The runway must have a declared landing distance available of at least 1,524 m.
2.1.10.7 The runway must have, or be qualified for, a precision approach Category I ILS procedure.
2.1.10.8 An OFZ must be established for the runway.
2.1.10.9 In consultation with the ATS provider and the relevant aeronautical telecommunications service and radio navigation service provider, the relevant ILS equipment critical and sensitive areas must be determined, documented and associated protection requirements defined in the aerodrome’s low visibility procedures.
2.1.10.10 The aerodrome operator must confirm with the relevant aeronautical telecommunications service and radio navigation service provider that the runway is equipped with a suitable precision approach aid.
2.1.10.11 Despite Chapter 9, a runway used for an SA Category I instrument approach operation is not required to have an approach lighting system extending over a distance of 900 m from the runway threshold.
Notes: 1: A runway with an existing Category II, Category III or SA Category II precision approach procedure is automatically eligible for SA Category I instrument approach operations.
2: Where possible, the runway should be equipped with an approach lighting system extending over a distance of at least 720 m from the runway threshold, which is either a precision approach Category I lighting system or a precision approach Category II and III lighting system.
3: The operating minima in each case are dictated by the available lighting facilities. Absence of an approach lighting system or a shorter approach lighting system will result in higher RVR minima. See the Manual of Standards (MOS) Part 173 – Standards Applicable to the Provision of Instrument Flight Procedure Design for specific details.
2.1.11 Runways Used for Special Authorisation Category II Instrument Approach Operations
Note: Special Authorisation Category II instrument approach operation is defined in AIP.
2.1.11.1 A runway is not suitable to be used for an SA Category II instrument approach operation unless all of the requirements in paragraphs 2.1.11.2 to 2.1.11.8 are met.
2.1.11.2 The aerodrome at which the runway is located must be a controlled aerodrome.
Note: Aircraft operators will not be permitted to conduct SA Category II instrument approach operations unless aerodrome control is in operation.
2.1.11.3 Subject to paragraph 2.1.11.9, the runway must meet all of the standards in this MOS for a precision approach runway Category II.
2.1.11.4 The runway must have electronic RVR equipment in the touchdown zone and at least 1 other zone of the runway.
2.1.11.5 The aerodrome operator must confirm with the ATS provider that the control tower has suitable RVR display equipment.
2.1.11.6 The runway must have a declared landing distance available of at least 1,830 m.
2.1.11.7 In consultation with the ATS provider and the relevant aeronautical telecommunications service and radio navigation service provider, the relevant ILS equipment critical and sensitive areas must be determined, documented and associated protection requirements defined in the aerodrome’s low visibility procedures.
2.1.11.8 The aerodrome operator must confirm with the relevant aeronautical telecommunications service and radio navigation service provider that the runway is equipped with a suitable precision approach aid.
2.1.11.9 Despite Chapter 9, a runway used for an SA Category II instrument approach operation is not required to have a precision approach Category II and Category III lighting system extending over a distance of 900 m from the runway threshold, runway centreline lighting or touchdown zone lighting.
Notes: 1: A runway with an existing Category II or Category III precision approach procedure is automatically eligible for SA Category II instrument approach operations.
2: Where possible, the runway should be equipped with an approach lighting system extending over a distance of at least 720 m from the runway threshold which is either a precision approach Category I lighting system or a precision approach Category II and III lighting system.
3: The operating minima in each case are dictated by the available lighting facilities. Absence of runway centreline lighting, touchdown zone lighting or an approach lighting system will result in higher RVR minima. Also, a shorter approach lighting system will result in higher operating minima. See the Manual of Standards (MOS) Part 173 – Standards Applicable to the Provision of Instrument Flight Procedure Design for specific details.
