Controlling RVR
I was talking to a captain about this. He told me that the only important RVR is the touchdown one as this is the legal one. Is this correct? The mid point and end point are advisory only. Does the take off RVR have to satisfy all 3 values as well?
Assuming you fly for a UK operator, all this information should be in your OM A. RVR requirements may depend on the type of approach/departure, what parts of the runway you are going to use and the actual visibility, so what you were told is incorrect as a blanket statement, although it may have applied to what you were doing at the time.
Once you get into LVOs, it becomes a bit more detailed with a fair amount of if/but/and, so worth a look.

RVR for landing: Touch down has to be above minima. Mid-point 125 m. Stop-end: 75 m.
RVR for takeoff: All three RVR measurements have to be above minimum RVR for takeoff.
Operating under EASA rules.

AMC1 CAT.OP.MPA.305(a) Commencement and continuation of approach
ED Decision 2022/012/R
MINIMUM RVR FOR CONTINUATION OF APPROACH — AEROPLANES
(a) The touchdown RVR should be the controlling RVR.
(b) If the touchdown RVR is not reported, then the midpoint RVR should be the controlling RVR.
(c) Where the RVR is not available, CMV should be used except for the purpose of continuation of an approach in LVO in accordance with AMC10 CAT.OP.MPA.110.
GM1 CAT.OP.MPA.305 Commencement and continuation of approach
(…)
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 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.
Always check Your OMA as it could be more restrictive (as ours is).
AMC1 SPA.LVO.100(a) Low-visibility operations and operations with operational credits
(…)The minimum RVR value specified in Table 1 or 2 should be achieved for all reporting points representative of the parts of the runway from the point at which the aircraft commences the take-off until the calculated accelerate-stop distance from that point.
Cheers.

For take-off - all sections used for take-off roll and RTO must be at or above minimums
For landing - as below:
On the website https://www.easa.europa.eu/community...r-operations-0 you can find AWO IMPLEMENTATION MANUAL V1.2
(or download directly via the link: https://www.easa.europa.eu/community...0checklist.pdf
I have found the following text on p.21
3.5.2 Approach ban – CAT.OP.MPA.305 and related AMC&GM.
(...)
5- Additional RVR information (e.g., midpoint and stop end) are advisory and they should allow the pilot to determine if sufficient visual reference exist to control the aircraft during roll-out and taxi.
Hope it helps
