I have spent much time reviewing the FAA and several other websites with concerns about how the certifications auto default down classes as time passes I do understand that if differs if you are over or under the ago of 40. So far I have you hold a class 1 for 12 months and then it defaults to a class 3 with a remaining 48 if you are under 40....then...if you are older than 40 you hold a first class for 6 months and it will auto default to a third class for a remaining 18 months. I am somewhat confused with the auto defaults??
Thanks,
