IR Implementing rule

## AWO.B.CATII.111 CS AWO.B.CATII.111 Installed equipment

The approach guidance system shall include:

(a) two xLS receivers with a display of the selected deviation information at each pilot’s station;

(b) an automatic approach coupler or a flight director system with display at each pilot’s station (or an alternative system capable of providing for equivalent performance and safety);

(c) a radio altimeter with displays at each pilot’s station of:

(1) radio altitude, and

(2) the selected DH (e.g. an index on an analogue scale or a digital indication);

(d) clear visual indication at each pilot’s station (e.g. an alert light) when the aeroplane reaches the pre-selected decision height appropriate to the approach;

(e) automatic or flight director go-around system or acceptable attitude indicators;

(f) audible warning of automatic pilot failure (for automatic approach);

(g) an automatic throttle/thrust system when required by CS AWO.B.CATII.106;

(h) an appropriate equipment failure warning system; and

(i) an alert of excess deviation from the required approach path, at each pilot’s station.

AMC Acceptable means of compliance

## AMC AWO.B.CATII.111 Installed equipment

(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 1, Chapter 3, and with 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) 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, and RTCA DO-253D, or equivalent standards.

(b) Radio altimeter equipment standard

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.
