A flight crewmember assigned to an augmented crew of 4 pilots with a Class 2 rest facility is not permitted to exceed which of the following cumulative limitations?

• A. 80 hours in any 672-consecutive-hour period
• B. 90 hours in any 672-consecutive-hour period
• C. 100 hours in any 672-consecutive-hour period
• D. 110 hours in any 672-consecutive-hour period

Answer: (C)

In the context of flight operations, the cumulative limitations set for flight crew members are designed to ensure safety and mitigate fatigue. An augmented crew, which consists of more pilots than the minimum required to operate a flight, offers opportunities for rest and recovery, allowing for more extensive operation periods.

For a crew of 4 pilots utilizing a Class 2 rest facility, regulations specify that these pilots should not exceed 100 flight hours in any 672-consecutive-hour period. This limit recognizes the additional support provided through an augmented setup, where crew members can rotate and rest more effectively than in standard operations.

Maintaining this threshold is crucial for ensuring that pilots remain alert and capable of performing their duties safely throughout the flight. Exceeding this limit could lead to increased risk of fatigue-related incidents, which is why it is strictly regulated.

The other options, while representing possible limits, do not align with the regulatory framework established for such flight operations with an augmented crew, reinforcing the importance of adhering to established guidelines for pilot operations.
