The Crew Duty Time Limitation Rule
Crew duty regulations are some of the strictest in aviation law. These rules dictate how long a pilot or flight attendant can work before mandatory rest is required. They exist because fatigue has been linked to decreased alertness and potential safety hazards in aviation history. International authorities such as the FAA, EASA, and ICAO enforce these standards globally.
On UA195, earlier delays in scheduling caused the crew to reach their maximum allowable hours mid-flight. Without the Halifax stop, the crew would have exceeded their legal duty limits before reaching San Francisco. By United Flight UA195 Diversion Halifax, United ensured compliance while preserving the ability to deliver passengers to their intended destination, albeit with a delay.
Crew Duty Time Framework Across Regions
| Region | Maximum Hours | Rest Requirements | Governing Authority | Notes |
| United States | 12-14 hours | 10 hours rest minimum | FAA | Dependent on number of segments |
| European Union | 13-15 hours | 11 hours rest minimum | EASA | Varies with time zones crossed |
| International (ICAO) | Guidelines vary | Country-specific adoption | ICAO | Harmonization efforts ongoing |
| Canada | 12-13 hours | 10 hours rest | Transport Canada | Aligned with FAA |
Details of the Halifax Diversion
The United Flight UA195 Diversion Halifax was executed smoothly and without incident.
