Show the text

Actual RVR minima to be used are subject to applicable operating regulations and may vary from one Member State to another taking account of local circumstances. For this reason, RVR minima should not be included in the aeroplane flight manual (AFM) as limitations. To aid operational assessment and the establishment of landing minima, the RVR values encountered during airworthiness certification should be given. In particular, the RVR values that are encountered during the certification of automatic or HUD ground-roll guidance should be provided in order to enable operational credits.

The aeroplane flight manual (AFM) may contain a statement that the categories of xLS ground facilities which have been used as the basis for certification should not be taken as a limitation. In that case, the AFM should also contain a statement that some Category I xLS ground facilities may be suitable for use by the approach and landing system.
