What is the minimum rest period a pilot must have within a 168-hour schedule?

The correct answer of 30 hours reflects the minimum rest period mandated for pilots within a 168-hour schedule, also known as a week-long duty cycle. This regulation is established to ensure that pilots have sufficient time to rest and recuperate between flying assignments, thereby maintaining safety standards in aviation operations.

Regulations typically stipulate that after certain duty periods, pilots must have a designated amount of rest to prevent fatigue, which is crucial for making effective decisions and maintaining operational standards. The 30-hour rest allows for adequate recovery time, thereby minimizing the risk of fatigue-related incidents when they return to flying duty.

While there may be varying rest requirements under different conditions or regulations, the standard for a 30-hour rest within a 168-hour window is crucial for managing pilot health and safety in aviation, making this the correct choice.
