Where does it state how office time (management pilot hours spent in the office) is counted towards 7 day, 28 day, yearly duty time?
Also, is it written somewhere discussing what percentage of office / flight time / duty
is required for management pilots? (this may vary country to country...) I have found 70 (office) / 30 (flight), but not in any official document.
I have searched to no avail.
