Triple 7 Yankee Mike - sorry that I've missed this thread. You need to get a UK (or JAA) commercial licence to be able to instruct for remuneration in the UK - if you're quick you may be able to get a UK BCPL, otherwise it'll have to be the obscenely expensive JAR-FCL CPL. To understand how to convert your FAA instructional qualifications to those which would allow you to instruct at PPL level in the UK on SE aeroplanes, you need to get hold of 'CAA General Information Document No 34' from Westward Digital ltd. Their telephone no is +44 (0) 1242 235151 or fax +44 (0) 1242 584139.
