The number of hours a pilot works per day is strictly governed by "Flight Duty Time Limitations" (FDTL) to prevent fatigue, but the actual "duty day" is often much longer than the time spent in the air. For commercial pilots under FAA or EASA regulations in 2026, the maximum Flight Duty Period (FDP) typically ranges from 9 to 13 hours for a single-pilot or two-pilot crew, depending on the start time and the number of flight segments. Actual "stick time" or flight time is usually capped at 8 to 10 hours within that window. These duty days include pre-flight briefings, weather analysis, aircraft inspections, and post-flight paperwork. Long-haul pilots may have extended duty periods up to 17 hours or more if they have a "reinforced" crew (extra pilots) and onboard rest facilities. After a full duty day, pilots are legally mandated to have a minimum rest period of at least 10 to 12 hours before they can be scheduled for their next flight.
