ED Decision 2023/007/R
APPLICATION OF RVR OR VIS REPORTS — AEROPLANES
(a) There is no prohibition on the commencement of an approach based on the reported RVR or VIS. The restriction in NCC.OP.230 applies only if the RVR or VIS is reported and applies to the continuation of the approach past a point where the aircraft is 1Â 000Â ft above the aerodrome elevation or in the FAS, as applicable.
APPLICATION OF RVR OR VIS REPORTS — HELICOPTERS
(b) There is no prohibition on the commencement of an approach based on the reported RVR. The restriction in NCC.OP.230 applies to the continuation of the approach past a point where the aircraft is 1Â 000Â ft above the aerodrome elevation or in the FAS, as applicable.
The prohibition to continue the approach applies only if the RVR is reported and is below 550Â m and is below the operating minima. There is no prohibition based on VIS.
(c) If the reported RVR is 550Â m or greater, but it is less than the RVR calculated in accordance with AMC5Â CAT.OP.MPA.110, a go-around is likely to be necessary since visual reference may not be established at the DH or MDH. Similarly, in the absence of an RVR report, the reported visibility or a digital image may indicate that a go-around is likely. The pilot-in-command should consider available options, based on a thorough assessment of risk, such as diverting to an alternate aerodrome, before commencing the approach.
APPLICATION OF RVR OR VIS REPORTS — ALL AIRCRAFT
(d) If a deterioration in the RVR or VIS is reported once the aircraft is below 1Â 000Â ft or in the FAS, as applicable, then there is no requirement for the approach to be discontinued. In this situation, the normal visual reference requirements would apply at the DA/H.
(e) Where additional RVR information is provided (e.g. midpoint and stop end), this is advisory; such information may be useful to the pilot in order to determine whether there will be sufficient visual reference to control the aircraft during roll-out and taxi. For operations where the aircraft will be controlled manually during roll-out, Table 1 in AMC1 SPA.LVO.100(a) provides an indication of the RVR that may be required to allow manual lateral control of the aircraft on the runway.
Guidance on commencing and continuing approaches under RVR/VIS reports, including helicopter-specific RVR limits, go-around considerations, and advisory RVR information for roll-out.
