Final answer:
The maximum flight duty time for a pilot on call is regulated by the FAA and is typically between 9 to 14 hours in a 24-hour period, including all on-duty activities, though this can depend on the specifics of their schedule.
Step-by-step explanation:
The question pertains to the maximum flight duty time for a pilot who is on call. According to regulations set by the Federal Aviation Administration (FAA), there are strict limits imposed to ensure safety and to prevent fatigue among pilots. These limits include mandatory rest periods and a cap on the number of hours a pilot can be on duty. For instance, in a 24-hour period, pilots are generally limited to a duty period of 9-14 hours for single crew operations, which includes flight time, pre- and post-flight operations, and any potential on-call waiting time. The exact limit can depend on the start time of the pilot's duty and any scheduled rest periods within their duty time. These rules help maintain safety standards similar to checklists, like the WHO surgical checklist mentioned, that aim to reduce workplace accidents.
