AMC5 SPO.OP.110 Aerodrome operating minima — aeroplanes and helicopters
DETERMINATION OF RVR OR VIS FOR INSTRUMENT APPROACH OPERATIONS — AEROPLANES
(a) The RVR or VIS for straight-in instrument approach operations should not be less than the greatest of the following:
(1) the minimum RVR or VIS for the type of runway used according to Table 7;
(2) the minimum RVR determined according to the MDH or DH and class of lighting facility according to Table 8; or
(3) the minimum RVR according to the visual and non-visual aids and on-board equipment used according to Table 9.
If the value determined in (1) is a VIS, then the result is a minimum VIS. In all other cases, the result is a minimum RVR.
(b) For Category A and B aeroplanes, if the RVR or VIS determined in accordance with (a) is greater than 1 500 m, then 1 500 m should be used.
(c) If the approach is flown with a level flight segment at or above the MDA/H, then 200 m should be added to the RVR calculated in accordance with (a) and (b) for Category A and B aeroplanes and 400 m for Category C and D aeroplanes.
(d) The visual aids should comprise standard runway day markings, runway edge lights, threshold lights, runway end lights and approach lights as defined in Table 8.

Simple approach lighting system (HIALS 420–719 m) single source, barrette |
|
BALS |
Any other approach lighting system (HIALS, MALS or ALS 210–419 m) |
|
NALS |
Any other approach lighting system (HIALS, MALS or ALS < 210 m) or no approach lights |
(e) For night operations or for any operation where credit for visual aids is required, the lights should be on and serviceable except as provided for in Table 15.
(f) Where any visual or non-visual aid specified for the approach and assumed to be available in the determination of operating minima is unavailable, revised operating minima will need to be determined.
EASA regulations mandate specific Runway Visual Range (RVR) or visibility (VIS) minimums for aircraft instrument approaches. These minima depend on runway type, lighting, decision height, and onboard equipment. Higher minima apply for approaches with level flight segments. Visual aids must be operational during night or low visibility operations.
