<strong>1. System minima</strong>
(i) An operator must ensure that system minima for non-precision approach procedures, which are based upon the use of ILS without glide path (LLZ only), VOR, NDB, SRA and VDF are not lower than the MDH values given in Table 3: <a title="System minima for non-precision approach aids" href="https://flightcrewguide.com/wiki/inflight/system-minima-non-precision-approach-aids/">System minima for non-precision approach aids</a>.
<strong>2. Minimum descent height
</strong>An operator must ensure that the minimum descent height for a non-precision approach is not lower than either:
(i) The OCH/OCL for the category of aeroplane; or
(ii) The system minimum.
<strong>3. Visual reference
</strong>A pilot may not continue an approach below MDA/MDH unless at least one of the following visual references for the intended runway is distinctly visible and identifiable to the pilot:
(i) elements of the approach light system;
(ii) the threshold;
(iii) the threshold markings;
(iv) the threshold lights;
(v) the threshold identification lights;
(vi) the visual glide slope indicator;
(vii) the touchdown zone or touchdown zone markings;
(viii) the touchdown zone lights;
(ix) runway edge lights; or
(x) other visual references accepted by the Authority.
<strong>4. Required RVR
</strong>The lowest minima to be used by an operator for non-precision approaches are: see Table 4 RVR for non-precision approach
<strong>5. Night operations</strong>
For night operations at least runway edge, threshold and runway end lights must be on.
