Hello Everyone!
Commission Regulation 2023/217 brings a change to the performance criteria for dispatching an aircraft. The requirements in points CAT.POL.A.230(e) and CAT.POL.A.235(e) should be applied cumulatively, not alternatively. Does it mean that during dispatch landing performance calculation both the 0 wind condition and the actual conditions have to be taken into account, according to the table in GM1 CAT.POL.A.230 & CAT.POL.A.235? Does it mean that in case of limiting performance with 0 wind the dispatch is not allowed even if the relevant criteria are met for the alternate aerodromes (one or two alternates) and/or performance is not limiting at probable wind with dry and wet runways? Can someone confirm this please?
Thank you.

Hi Mark,
That is correct, if no performance for the most favourable runway (normally the longest) at no wind, dispatch is not possible. Exception is made, if the runway is contaminated (2 alternates required).
