What is the maximum number of hours for Part 135 Scheduled pilots in a 12-month period?

• A. 1000 hours
• B. 1100 hours
• C. 1200 hours
• D. 1300 hours

Answer: (C)

In Part 135 scheduled operations, there’s a clear limit on how many flight hours a pilot can accumulate in a rolling 12-month period. The maximum is 1,200 hours in any 12 consecutive months. This rolling window approach means the count isn’t tied to a calendar year; it slides forward as time passes, so you must stay at or below 1,200 hours within the current 12-month lookback.

Why this matters: the limit is part of the flight time limitations and fatigue management framework. It allows scheduled operations to run consistently while ensuring pilots aren’t overworked over the long term, preserving safety and alertness. When the 12-month window approaches 1,200 hours, adjustments in scheduling or rest periods are needed to stay compliant.

The other numbers aren’t the standard maximum for this category; they might appear in other contexts or operator-specific rules, but the official cap for Part 135 scheduled pilots is 1,200 hours.
