For IFR flights that require two alternates, is there a regulation that requires enough fuel to reach the furthest one? For flights that have two alternate destinations, I'm looking for a reference - either EASA or ICAO - that states that you need enough fuel to reach whichever alternate would require the most fuel to get to.

I think this is common sense, but I need a reference if anyone has it?
EASA OPS 1.255, appendix 1, 1.4 b).

I don't have the text in English here, sorry.
