Frog, whilst you had your UNHAPPY TONE on to admonish IO540, you managed to avoid a point he raised which i wanted to raise too! Namely, how does a French VFR pilot flying LEGALLY VFR ON TOP usally on airways too, infering more than a local bimble hence various weather systems to consider!(Note:- VFR ON TOP/AIRWAYS Not Legal in UK) make a safe approach to land when the destination is clagged in? You have already stated the IMC could lead pilots in to weather that wasnt forcast, so you cant use the explanation that they had a good briefing before departure! Don't you think it is a little ironic that the French hate the IMCR but allow VFR ontop, whereas the British have the IMCR and dont allow VFR on top?
Also, to try to move this debate along, what do you think needs to added to the IMC training cyllabus to make it an acceptable IFR licence for the GA pilot?
