Final answer:
Commercial pilots are restricted to 100 flight hours in any 672-hour rolling period under FAA regulations, with the specific Flight Duty Period (FDP) limits depending on various factors. Pilots must adhere to these regulations and be aware of additional requirements such as rest periods and cumulative limits.
Step-by-step explanation:
The amount of flight hours and Flight Duty Period (FDP) hours an individual is legally permitted to work within a specific time frame, such as a 672-hour rolling period, is governed by aviation regulation. These regulations can vary significantly depending on the jurisdiction and the regulatory body that oversees civil aviation operations, such as the Federal Aviation Administration (FAA) in the United States or European Union Aviation Safety Agency (EASA) of Europe.
In the United States, under the FAA rules, Part 117 - Flight and Duty Limitations and Rest Requirements for flight crewmembers, prescribes limits on flight hours. As of the knowledge cutoff date, the FAA limits commercial pilots to 100 flight hours in any 672 consecutive hours (equivalent to 28 days). However, this limit is subject to additional caveats such as 1,000 flight hours in a calendar year. For FDP hours, the limits are dependent on a variety of factors including the start time of the FDP, the number of flight segments, and required rest periods.
It is critical for pilots and aviation personnel to be familiar with their relevant regulatory body's specific rules and amendments to ensure compliance. Along with the limits on flight times and FDPs, there are requirements for minimum rest periods between duties, and cumulative duty period limitations which must also be considered.
