Under FAR Part 135 regulations, the maximum length of a duty day for pilots is indeed 14 hours. This regulation is designed to ensure safety in aviation operations by preventing fatigue among flight crews. The 14-hour limit applies when certain conditions are met, such as when the pilots are operating under specific flight rules and when they start their duty day at a base location.

The rationale behind this limit is based on extensive research suggesting that fatigue significantly impairs cognitive and physical performance, increasing the risk of accidents. The regulation aims to balance operational demands with the need for adequate rest, thereby enhancing overall safety.

In circumstances where pilots are engaged in flight operations beyond the specified duty limits, additional factors and regulations may apply, such as resting requirements or adjustments based on the time of day. This structured approach helps ensure that pilots are fit for duty, promoting safer flying conditions.
