geoffers - yes it is a difficult issue but assumes if the RFM says Vmini is say 50 kts then it is not possible to fly the aircraft on instruments below that speed, something we all know is not true.
tistisnot - yes, the correct decision would have been to stay on the ground but the reality is that owners/hirers will continue to press pilots to go when logic says not. At least have a technique in your repertoire to deal with that rather than spear in under pressure.
