In on-demand operations, what is the rest requirement after a flight time of at least 11 hours and 1 minute?

In on-demand operations under Part 135 regulations, the required rest period after a flight time of at least 11 hours and 1 minute is 16 hours. This is designed to ensure that flight crew members have adequate time to recover and rest after long periods of operation, thereby enhancing safety and preventing fatigue-related incidents. The 16-hour rest requirement reflects the understanding that longer flight times demand more recovery time, allowing pilots and crew to be well-rested and alert for their next flight. Additionally, this requirement aligns with regulations intended to promote better overall health and performance among flight personnel.

Understanding the rigorous demands of flight operations is crucial, as non-compliance with rest requirements could pose significant safety risks and may result in regulatory penalties or operational disruptions.
