The regs use terms like PIC and although your contract equates PIC with captain, the regs do not. Ability to " Hold captain" and "Seniority" are not conditions of regulatory compliance.
I think that's true of nautical regs as well. The person in ultimate charge of a vessel is the "Master", even though usually referred to as "Captain".
