What is the maximum flight limit for a flight engineer on a Part 121 Flag Flight where only one FEX is required?

The maximum flight limit for a flight engineer on a Part 121 Flag Flight, where only one Flight Engineer is required, is established at 120 hours during any 30 consecutive days. This regulation is in place to ensure safety and manage fatigue among flight crew members. The regulation considers factors such as the nature of long-haul flights, which often involve extended duty periods and require adherence to strict standards for crew rest and operational efficiency.

Understanding this limit is crucial for flight engineers as it impacts scheduling, compliance with federal aviation regulations, and overall crew wellness. The maximum of 120 hours reflects an understanding of the demands placed on flight engineers during longer flights while maintaining safety protocols. In contrast, the other options present either lower or higher limits that do not align with the established regulatory framework.
