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 infor mation at each pilot's station;

\- (b) a n 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) c lear 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

ED Decision 2022/007/R

The approach system shall cause no sustained nuisance oscillations or undue attitude changes or control activity as a result of configuration or power changes or any other disturbance to be expected in normal operation.

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.
