I’m trying to determine international flight hour limits and find it confusing.

How does crew scheduling track this if one has both flying trips and non-flying (FO and RFO) in the same month.

How about when you have domestic and international in the same month?

Seems like with all these revisions I am close to going over limits . it’s not easy for me to figure it all out.

Anyone have an easy way to figure it all out?

Thanks in advance.
