How many hours of duty time is permitted in a week?

The correct response aligns with the regulations governing duty time for pilots operating under Part 135. Under these regulations, pilots are permitted a maximum of 34 hours of duty time in a week. This limit is established to help manage pilot fatigue and ensure safety in operations, reflecting the need for rest and adequate recovery time for flight crews.

In specific contexts, such as varying operational demands or extended duty assignments, the regulatory structure emphasizes the importance of adherence to these limits to promote both pilot well-being and aviation safety. Therefore, 34 hours is the established benchmark recognized by regulatory agencies for weekly duty time, underscoring the commitment to maintaining rigorous standards in flight operations.
