What is the maximum on-demand flight time allowed in a calendar year?

The maximum on-demand flight time allowed in a calendar year under Part 135 operations is indeed 1400 hours. This limitation is established to ensure safety and manage fatigue among flight crews, as well as to regulate the operational capacity of air carriers. By setting this limit, the regulations help to maintain a high standard of safety and operational integrity within the aviation industry. The 1400-hour guideline is crucial for ensuring that pilots have adequate rest and are not overworked, striving to prevent fatigue-related incidents and promoting overall flight safety.

Flight operations under Part 135 are closely monitored, and exceeding this limit could result in regulatory penalties or operational restrictions, thereby underscoring the importance of adhering to established safety standards.
