Thanks BEagle,
Then its as I feared, I`d got a mistaken impression that the OPC (what`s the O for ?) concession overrode the 12 hr or LPC bit.
Another angle I was thinking of was using the National Licence when it comes out but this is still going to be subject to the LPC and maybe 5 hrs.
Yet another approach could be to use the foreign licences` private privileges and validity (same as pre JAA UK), but I believe this is governed by more JAA interpretation instead of the straightforward old ANO 21 (4). Its difficult to check as I don`t know anyone who can afford a copy of JAR FCL.
Its all nearly as daft as having to maintain 3 instrument ratings, 1 for work ( done to pre JAA UK standards ), 1 for weekend gun running with Bill (UK multi crew) and 1 for taking the family to Alderney in a Seneca (UK single crew).
Is it unreasonable to want to circumvent these duplications ?. I`ve already said its reasonable to require a check before someone rents you an aeroplane.
