Approach ban inside the OM on LVO
Dear All,
-
I have searched the achieves and cannot find an old thread on the subject.
-
I have two opinions on this subject both from TREs, I would be grateful for the forum's help.
-
On a CAT 3 approach inside the OM or equivalent position, A/C Indicating LAND 3 (fail operational) TD RVR 100m (LAND 3 requires 75m). An on board failure occurs which downgrades the A/C to LAND 2 (fail passive) (LAND 2 requires 200m).
-
Question. Should the commander Go-around as the required RVR is not now available, or can the commander continue down to the LAND 2 minima of 50ft and assess if the required visual reference is available?
-
I have added some JAR-OPS 1 below.
-
JAR-OPS 1.405 Commencement and
continuation of approach
(a) The commander or the pilot to whom
conduct of the flight has been delegated may
commence an instrument approach regardless of the
reported RVR/Visibility but the approach shall not
be continued beyond the outer marker, or equivalent
position, if the reported RVR/visibility is less than
the applicable minima. (See [JAR-OPS 1.192].)
(b) Where RVR is not available, RVR values
may be derived by converting the reported visibility
in accordance with Appendix 1 to JAR-OPS 1.430,
sub-paragraph (h).
(c) If, after passing the outer marker or
equivalent position in accordance with (a) above, the
reported RVR/visibility falls below the applicable
minimum, the approach may be continued to DA/H
or MDA/H.
