Just trying to help you here Josh..
Josh.. it's surprising and disappointing that you think that a cardiologist's report will ensure the issue of your Class 1. For my part I genuinely hope that you get your Class 1 and are able to follow your dream. Please do keep us posted.
Realistically however (IMHO) the CAA Aeromedical folks will still have to apply the EASA BMI criteria... regardless of such a report...BMI issues embrace wider issues than simple cardiology.
This ol boy has spent enough time in a scrum to feel for your predicament but securing a Class 1 via the route suggested does not address your other predicament ... making yourself a viable candidate for future employent... and it is a worry that you're only now addressing this issue at age 32.
Before I get flamed, please note that there is no criticism..implied or stated.. in this reply. Cheers, TP
