8.1.6.1 Definitions. In paragraphs 8.1.6.1A to 8.1.6.1D:
APLL, in relation to a runway, means:
(a) the length of an ALS, for the runway, in metres; or
(b) if there is NALS in relation to the runway — zero metres.
MDH means minimum descent height.
straight-in approach procedure aligned with runway centreline means a straight-in approach procedure, for a runway, which:
(a) utilises precision approach (ILS or GLS), ILS localiser, GNSS, VOR, or NDB, guidance for the final approach segment, and
(b) for which the final approach track is offset by:
(i) for a Cat A or B aeroplane — not more than 10 degrees from the runway centreline; or
(ii) for a Cat C or D aeroplane — not more than 5 degrees from the runway centreline.
TCH means threshold crossing height.
VPA means vertical path angle, in degrees.
8.1.6.1A Application of procedures for determining minimum RVR, or visibility, for certain straight-in approach procedures. The procedures for determining minimum RVR, or visibility, under paragraphs 8.1.6.1B and 8.1.6.1C apply to any of the following straight-in approach procedures:
(a) a precision approach procedure with a DH of not less than 200 ft;
(b) an approach procedure with vertical guidance;
(c) a non-precision approach procedure;
which meets the PANS-OPS Vol II, or ICAO Doc 9905, requirements for a straight-in approach procedure.
8.1.6.1B Method for determining minimum RVR or visibility — straight-in approach procedure aligned with runway centreline. Subject to paragraph 8.1.6.1D, for a straight-in approach procedure mentioned in paragraph 8.1.6.1A, which is a straight-in approach procedure aligned with runway centreline, the minimum RVR, or visibility, for the procedure is the greater of the following:
(a) ;
(b) the value, as an RVR or visibility, stated in column 1, 2, 3 or 4 of Table 8.1, relevant to the type of ALS in relation to a runway stated in the first row of the table.

Distance (metres) | 550 | 800 | 800 | 1,000 | 1,200 | 1,500 |
8.1.6.1C Method for determining minimum RVR or visibility — other straight-in procedures. Subject to paragraph 8.1.6.1D, for a straight-in approach procedure mentioned in paragraph 8.1.6.1A, which is not a straight-in approach procedure aligned with runway centreline, the minimum RVR, or visibility, for the procedure is the greater of the following:
(a) ;
(b) 1 500 m.
8.1.6.1D Use of RVR minimum. For paragraphs 8.1.6.1B and 8.1.6.1C, an RVR minimum may be used only for a procedure to approach a runway equipped with electronic RVR measuring equipment.
8.1.6.2 Maximum RVR or visibility. For a straight-in approach procedure, the maximum RVR, or visibility, for the procedure is 5 km.

Note: The values in Table 8-2 have been determined allowing for an omni directional wind of 25 knots, an achieved bank angle of 25°, an OAT of ISA + 15, an altitude of aerodrome elevation plus 1,000 ft and the average visual manoeuvring speed for the aircraft category. Subject to an absolute minimum value of 2 km, the values were derived using the following formula: V = 0.9D Where V = circling visibility D = diameter of turn at the average manoeuvring speed for category 0.9 = minimum downwind spacing, in nautical miles, to achieve alignment on final approach. The circling visibility recognises that the pilot of the aircraft must be able to see the runway from the downwind position. |
