Re: JAR Compliant PPL vs JAA PPL - Difference?
All a bit silly really isn't it. The School concerned is using confusing language to market its product and the frequency with which this question arises demonstrates the confusion created.
With an FAA PPL and an FAA Medical, you are fully entitled to fly G-reg aircraft all over the world thanks to the ANO rendering all ICAO PPLs valid.
Why would you bother going through the subsequent rigmarole of getting a JAA licence unless you had a particular need to add later JAA ratings to it? And if that is the case, then why not simply go to a JAA school (in the UK or US) and get your JAA licence directly.
