Correct me if I'm wrong, but isn't there no such thing as a night rating? Isn't it a night qualification?
Pedantry aside, as part of "operation get my SEP rating back" (which starts with an instructor at 1400 this afternoon) I intend to do some night flying. Even though it isn't a rating in that I have to renew it, I haven't flown at night for nearly 10 years so I want to spend a few hours with an instructor before I fly by myself at night again...
