Min RVR for take off - EASA rules
Hi everybody,
AMC1 SPA.LVO.100 states that for day operations on runway equipped only with runway edge lights and runway centre line markings minimum required RVR is 300 m.
Also it states that the reported RVR value representative of the initial part of the take-off run can be replaced by pilot assessment.
At the same time the aerodrome Certification Standard states in CS ADR-DSN.M.690(2) Runway centre line lights SHOULD be provided on a runway intended to be
used for take-off with an operating minimum below an RVR of the order of 400 m.
I understand that CS's similar level document as the AMC's so there we have two conflicting regulations.
AMC allows take off with RVR of 300 m but the airport is certified bz the local authority for min 400 m RVR.
So now I have a few questions
Suppose that the METAR report states that RVR is 300 m in all three points.
The question - is pilot allowed to taxi into line-up position to assess the RVR value on the initial part ?
And can he/she take off legally?
Who decides on that - airport operator, pilot or maybe ATC ?
Can somebody shed some light on this I am confused.
It is not just an academic question - flight have been already cancelled based on this 400 RVR min requirement...
