Pilots were restricted to flying how many hours per month and how many hours in any 12-month period?

• A. 50 per month and 500 per 12 months
• B. 100 per month and 1000 per 12 months
• C. 120 per month and 1500 per 12 months
• D. 80 per month and 800 per 12 months

Answer: (B)

Fatigue management relies on clear flight time limits that cap how much a pilot can fly in set periods. The standard limits are 100 hours in any calendar month and no more than 1,000 hours in any 12-month period. The month limit prevents large h blocks of flying in a single month, while the 12-month limit stops cumulative fatigue from building up over the year. The 12-month constraint is typically a rolling window, so at any point you look back over the previous 12 months to ensure the total hasn’t exceeded 1,000 hours. These limits together help ensure pilots have adequate rest and recovery between duty periods.
