What does the acronym FDP stand for in aviation terms?

The acronym FDP in aviation terms stands for Flight Duty Period. This refers to the total time a flight crew is on duty, which includes the time spent preparing for the flight, during the flight, and any time spent after the flight before they can conclude their duty. The regulation surrounding the Flight Duty Period is crucial for ensuring safety, as it helps maintain crew alertness and effectiveness, thus minimizing the risk of fatigue-related incidents.

The other options refer to concepts that are not part of standardized aviation terminology or do not accurately represent the regulatory framework concerning the working hours of flight crews. Understanding the context of Flight Duty Period is critical for aviation professionals in managing schedules, complying with regulations, and ensuring flight safety.
