Flight time limitations and rest requirements: Scheduled operations

This regulation sets flight time limits and rest requirements for Part 135 scheduled operations. Flight crewmembers cannot exceed 1,200 hours yearly, 120 hours monthly, 34 hours in any 7 consecutive days, or 8 hours in 24 consecutive hours (single pilot or two-pilot crews).

Before any flight segment, crewmembers must receive scheduled rest during the preceding 24 hours: 9 hours for flights under 8 hours, 10 hours for flights of 8-9 hours, or 11 hours for flights over 9 hours. These rest periods can be reduced to 8 or 9 hours minimum if compensatory rest of 10-12 hours begins within 24 hours of the reduced rest period starting.

Additionally, every crewmember must receive at least 24 consecutive hours free from all duty during any 7-day period. These rules apply to both the certificate holder's scheduling and the crewmember's acceptance of assignments, ensuring adequate rest for safe operations.
