This course outlines the rules that operators must follow to keep flight crews free from fatigue and maintain safety. It defines key terms such as duty period, flight duty period (FDP), flight time, home base, rest period, and standby. Operators must publish duty rosters early, limit duty hours to 60 in 7 days, 110 in 14 days, and 190 in 28 days, and cap flight time at 100 hours in 28 days, 900 in a calendar year, and 1,000 in 12 months.

Minimum rest before an FDP is 12 hours at home base or 10 hours away, with an 8‑hour sleep requirement. In‑flight rest and unforeseen circumstances allow limited extensions, but commanders must consult crews and avoid excessive fatigue. The course also covers standby duties, accommodation, and rest after standby.
