BY "maintain", I mean doing the two hours minimum per annum (one of which may be one's Licence Proficiency Check!) per rating. However, being realistic, there is no way I would/should pass an LPC if I have only done one flying hour in the year prior on that machine, especially as I would probably only have 15 hours in total!! I did my JetRanger hours in South Africa where their rating isn't valid in JAA-land without jumping through some ridiculous hoops which would have made it cheaper to do it in the UK anyway - I just flew with an instructor!
