The approach guidance system shall include the following:

- (a) two separate navigation receivers or demonstrated equivalent devices with a display of the selected deviation information at each pilot's station; - (b) a flight guidance system (or an alternative that provides for equivalent performance and safety) with displays at each pilot's station; - (c) a radio altimeter (or other device capable of providing for equivalent performance and integrity level) with displays at each pilot's station of: - (1) height above terrain; and - (2) the selected decision height (DH); - (d) clear visual indication at each pilot's s tation (e.g. an alert light) when the aircraft reaches the preselected DH appropriate to the approach; - (e) automatic or flight director go-around system or any other attitude indicators that can achieve the required performance, accuracy and function; - (f) audible warnings of automatic pilot failure (for automatic approach) (refer to CS 25.1329); - (g) an automatic throttle/thrust system, where necessary (see CS AWO.B.CATII.106); - (h) an appropriate alerting system; and - (i) an alert of excess deviation from the required approach path, at each pilot's station .

ED Decision 2022/007/R

The recognition of the decision height (DH) shall be made by means of height measured by a radio altimeter or another system that provides height above terrain with equivalent performance, accuracy, integrity, availability, level of independence, and dissimilarity.

(a)xLS airborne equipment standards

Acceptable standards for airborne receiver equipment include the following:

- (1) Localiser receivers that comply with the minimum performance standards of EUROCAE ED-46B or later revision, or an equivalent standard, and glide path receivers that comply with the minimum performance standards of EUROCAE ED-47A or RTCA DO-192 or later revision.

Note: The aforementioned localiser specifications are in accordance with the FM Broadcast Interference Immunity requirements of ICAO Annex 10, Volume I, Chapter 3, and paragraph 3.1.4.

- (2) MLS receivers that comply with the minimum performance standards of EUROCAE ED-36A or later revision, or an equivalent standard, and DME/P or DME/N transceivers that comply with the minimum performance standards of EUROCAE ED-54 or RTCA DO-189. - (3) Combined ILS/MLS receivers that comply with the minimum performance standards of EUROCAE ED-74 or equivalent standard. - (4) Combined ILS/MLS/GPS receivers that comply with the minimum performance standards of EUROCAE ED-88 or equivalent standard. - (5) GLS receivers, or combined ILS/MLS/GPS/GLS receivers, or combined ILS/GPS/GLS receivers, which comply with the minimum performance standards of EUROCAE ED-88, RTCA DO-246E or later revision, and RTCA DO-253D or later revision, or equivalent standards.

(b)Flight guidance system

Potentially acceptable flight guidance systems for SA CAT I operations include the following:

- (1) HUDs (or equivalent displays) with flight guidance that comply with CS-AWO Subpart A, Section 2, and Subpart B, Section 3. - (2) SVGSs that comply with CS-AWO Subpart A, Section 4. - (3) Automatic approach systems that comply with CS-AWO Subpart A, Section 1, combined with a HUD (or equivalent display) that complies with AMC 25.11, to help with the flight path monitoring and control after the DH. - (4) Automatic landing systems that comply with CS-AWO Subpart A, Section 1, using a CAT I ILS beam model, and CS-AWO Subpart B, Section 3. - (5) Automatic landing systems as defined in (4) with a HUD (or equivalent display) that complies with AMC 25-11 to help with the flight path monitoring before and after the DH. - (6) Any other flight guidance system that can demonstrate the required performance of Subpart B Section 2.

Easy Access Rules for All-Weather Operations (CS-AWO)

- (c) Radio altimeter equipment standards

The airborne equipment used to provide height above terrain may be a radio altimeter that complies with the minimum performance standards of EUROCAE ED-30 or RTCA DO-155. Alternatively, another device capable of providing equivalent performance and integrity level may be used.
