What is the basic rest requirement for on-demand operations?

In the context of Part 135 on-demand operations, the basic rest requirement is established to ensure that flight crew members have adequate recovery time between duty periods. According to regulatory guidelines, pilots are required to have at least 10 consecutive hours of rest prior to a new duty period. This 10-hour rest period is designed to promote alertness and fatigue management, allowing crew members to perform their duties safely and effectively.

The focus is on ensuring that pilots are well-rested, as fatigue can significantly impair cognitive functions and overall performance during flight operations. Therefore, adherence to this rest requirement is critical in maintaining safety standards in aviation operations.
