Does anybody happen to know the requirements for a LTLOA? I've been told different things by different people. Specifically, do you need to be current and in the correct seat to be awarded one? And if so, what is the reference?

I'm currently on the 200, but moving across to the 900. However, I've been out on short term disability for the last month. Do I need to have been trained up on the 900 to be awarded an LTLOA?
