What is the domestic flight time limit for a Flight Engineer in any calendar month?

The domestic flight time limit for a Flight Engineer within a calendar month is indeed 100 hours. This regulation is established to ensure that flight engineers maintain a high level of alertness and performance, which is crucial for safety within the cockpit environment.

The limit is based on studies and operational experience that indicate how fatigue can affect performance. By capping the monthly flight time to 100 hours, the regulatory standards help prevent fatigue-related incidents and ensure that flight engineers have adequate rest and recovery time between duty periods. This limit is consistent across various regulatory frameworks governing aviation operations, thereby promoting safety in the industry. By understanding this standard, flight engineers can also better manage their schedules to comply with both regulatory requirements and best practices for operational safety.
