Hi floting feather,
Seems like a late reaction, but was searching for pilots with asthma so after a long search i saw this forum

I had the class 1 medical (JAR-FCL3) in Amsterdam/Holland couple of months ago, and i also was adviced to go to a specialist. First results at the medical: FEV1 67% Peakflow 75% and FEV1/FVC 49%. Resent results from the specialist: FEV1 78.3% Peakflow 100% and FEV1/FVC 51.58%.
Floting feather, you're saying your 72% FEV1 is sufficient for the class1 medical. Are you sure you mean the FEV1 or is it the FEV1/FVC?
Greetings Alex
