Can a pilot commence an approach when the reported RVR is below the operating minima?

Yes, there is no prohibition on the commencement of an approach based on the reported RVR or VIS. The restriction in CAT.OP.MPA.305 applies only to the continuation of the approach past a point where the aircraft is 1 000 ft above the aerodrome elevation or in the final approach segment, as applicable.

What is the advisory nature of additional RVR information such as midpoint and stop end?

Additional RVR information is advisory; it may be useful to the pilot to determine whether there will be sufficient visual reference to control the aircraft during roll-out and taxi.

GM1 CAT.OP.MPA.305 Commencement and continuation of approach

Q: For aeroplanes, at what point does the restriction on continuing an approach based on reported RVR or VIS apply?

The restriction applies to the continuation of the approach past a point where the aircraft is 1 000 ft above the aerodrome elevation or in the final approach segment, as applicable.

Q: If the reported RVR is 550 m or greater but less than the RVR calculated per AMC5 CAT.OP.MPA.110, what should the commander consider?

A go-around is likely to be necessary since visual reference may not be established at the DH or MDH. The commander should consider the available options, based on a thorough assessment of risk, such as diverting to an alternate, before commencing the approach.

Q: In the absence of an RVR report, what might indicate that a go-around is likely?

The reported visibility or a digital image may indicate that a go-around is likely.

Q: If a deterioration in RVR or VIS is reported after the aircraft is below 1 000 ft or in the final approach segment, must the approach be discontinued?

No, there is no requirement for the approach to be discontinued. In this situation, the normal visual reference requirements would apply at the DA/H.

Q: Where can pilots find an indication of the RVR required for manual lateral control during roll-out for aeroplanes?

Table 1 (aeroplanes) in AMC1 SPA.LVO.100(a) provides an indication of the RVR (e.g. midpoint and stop end) that may be required to allow manual lateral control of the aircraft on the runway.

Q: Where can pilots find an indication of the RVR required for manual lateral control during roll-out for helicopters?

Table 3 (helicopters) in AMC2 SPA.LVO.100(a) provides an indication of the RVR (e.g. midpoint and stop end) that may be required to allow manual lateral control of the aircraft on the runway.

GM1 CAT.OP.MPA.305 Commencement and continuation of approach

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 CAT.OP.MPA.305 applies only if the RVR or VIS is reported and applies to the continuation of the approach past a point where the aircraft is 1 000 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 CAT.OP.MPA.305 applies to the continuation of the approach past a point where the aircraft is 1 000 ft above the aerodrome elevation or in the final approach segment as applicable.

The prohibition to continue the approach applies only if the RVR is reported and it is below 550 m and below the operating minima. There is no prohibition based on VIS.

(c) If the reported RVR is 550 m or greater, but it is less than the RVR calculated in accordance with AMC5 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 commander should consider the available options, based on a thorough assessment of risk, such as diverting to an alternate, 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 1 000 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 is controlled manually during roll-out, Table 1 (aeroplanes) in AMC1 SPA.LVO.100(a) and Table 3 (helicopters) in AMC2 SPA.LVO.100(a) provide an indication of the RVR (e.g. midpoint and stop end) that may be required to allow manual lateral control of the aircraft on the runway.
