OK
Having just swopped my UK CAA ATPLA for a new JAR-ATPLA one of my concerns was what about my IMC privileges...well on my new "ratings" page there has appeared a new 'national rating" IMC to go along with my full instrument rating. As a national rating it is of course only valid in the UK.
My IR for single pilot operations hasn't been used for about 9 years , but if I wanted to renew it the requirements would be based on the last expiry of my Multi pilot IR (which is current). So a fairly straight forward test as opposed to the nightmare of letting the whole thing lapse for that long.
