Hi - thanks for the replies,

thanks for the info. Looks hopeful as seems pretty similar to requirements on NPPL for diabetes with tablets, eg met DVLA group requirements. So think i'm ok there with a bit luck on this one.

Thanks, was aware that there are some type of grandfather rights to old CAA PPL A's. However, think i read somewhere that they are trying to get rid of them on the lifetime basis by not letting anyone actually be able to sign off CAA only JAA licences and hence the need to convert it to a JAA which is on a renewal fee basis. As regards experience its been a long time since 1992 so doing the whole thing wouldn't be a bad idea albeit more expensive,
