Contract. Search it. Please try, it is horrific how many pilots don't even attempt or read it in its entirety. A lot of good useful information for your daily life. You know a lot of people, even CAs, dont know you can commute in the first 2hrs of your reserve window?
25.F.2.a if the section you are looking for.
