What is also lunatic is the "almost certain" stipulation - one can only assume that the idiot who recommended this is not a pilot.
Does JAR-OPS1 (or EU-OPS now) not require that before you depart on an IFR flight the weather at either your destination or an alternate is forecast to be "almost certainly" above your operating minima? Is that also mindless bureaucracy that couldn't have come from a pilot?
