Agree with G RICH - the 10 sittings rule is going to throw up obvious problems, and some of the nav questions are simply ridiculous at PPL level. Who on earth at the CAA is overseeing or monitoring this exam process? None of it bears any relevance or enhances training at the private pilot level. If the CAA is only going to deal with 'corporate bodies' then AOPA needs to get a very public grip on this, and soon!
