FF, I'm intrigued by your comment about differences training lapsing after two years.
I've seen a clear statement on an FAQ site that exactly the opposite is the case ie that revalidation of the SEP (land) covers all types / variants for which you have had differences training even if no time has been flown on that type in the qualifying period. Thats aside from being current from an insurance, common-sense, or good airmanship perspective of course!
Also, how does differences training and the lapsing of same apply to what I believe are called "grandfather rights" on a CAA (pre-JAR) licence?
