Class1 to Class2
It is not as straitforward as it appears.
A CAA class 1 medical used to automaticaly become a class 2 and was valid as such. I understand from my AME and the CAA that this is not the case with the JAA medical. The solution I was given was to obtain a Class 2 at the same time as the Class 1 medical. Then if you dont renew your class 1 you can still fly on the class2.
It doesnt cost anything extra to do this.
