In the UK, commercial pilot flight times are strictly regulated by the Civil Aviation Authority (CAA) to prevent fatigue. As of 2026, a pilot's "Flight Duty Period" (FDP)—which includes pre-flight prep and post-flight duties—is generally limited to 9 to 13 hours in a single day, depending on the start time and the number of flight sectors (takeoffs and landings). The actual "stick time" or flying hours are typically capped lower, often around 9 to 10 hours for a standard short-haul shift. These limits can be extended slightly for long-haul crews that include "augmented" staff (extra pilots) who can rest in onboard bunks. Furthermore, UK pilots are restricted to 900 flying hours per year. These safety-critical rules ensure that flight decks are manned by alert, rested professionals, particularly during the busy 2026 summer charter seasons.
