Congrats!. Class II
means that you can fly commercially. To whit: you can fly passengers and accept payment for gas. Class III CANNOT! Even if your best friend offers to pay for gas, you cannot accept it! Federal regulations. The visual requirements for II
are a bit more rigorous than III, but not much, really. As for the validity, Class I automatically reverts to Class II
after 6months, unless I is renewed. Similarly, II
reverts to III for 2-3 years, if it is not renewed. I ultimately degrades to class III with time. EKGs are required for class I, as is audiometric testing, which is not mandatory for (ahem) the lower classes.
Enjoy, but remember, that certificate is privilege, not an entitlement. You earned it. Treat it with respect, and you will get home safely.
