JoshG .... best of luck.
I got my Class 2 revoked becuase I was dim, daft and dopey enough to issue the CAA with a copy of my echocardiogram which revealed an LVEF of about 48% .... which despite considerable sympathy from Rob Hunter was just insurmountable because it has to be over 50%.
Never mind that the FAA would accept down to 45% but I don't have a directly issued FAA license and that I passed Gatwick's cardiac exercise stress test without problems, it was still a No NO.
Silly part is that it may have been at that level for years and as it isn't a required test could have remained undiscovered forever.
