As DH said, i think left is worse than right. I cant remember why.
Mine is a RBBB. I was originally turned down by RAF and CAA some years back, the CAA rules have changed as of November 2005. I couldnt get my Class one as i couldnt be issued with a Initial Class 1 restricted. This has now changed. I was the first one to get a 1st Class inital restricted issued. I do have 2000 Hours now too flying on my FAA CPL/IR, so i dont know if that was taken into account too.
I was told late 2005 to see a specialist the CAA recomended in London and they would go on his say so and i had to have a less than 1% chance of the condition worsening ever year.
So yes you can now fly as of it, i am restricted to As or with Co Pilot.
As i said in my PM call me if you like, i may be able to explain it better.
