Final Answer:
A Split Duty Trip (SDT) requires a scheduled and actual rest period behind the door of at least 8 hours between the hours of 8:00 PM and 4:00 AM. This means that the rest period, whether scheduled or actual, must encompass a duration of 8 hours and fall within the specified time window. Option c) 8 hours; 8:00 PM and 4:00 AM aligns with this requirement, making it the correct choice.
Step-by-step explanation:
In aviation regulations, "behind the door" denotes the period when flight crew members are off-duty and secluded in a suitable facility, usually a hotel, to ensure adequate rest between duty periods.
The _8-hour_ rest duration is crucial for the well-being of the flight crew, allowing them to recuperate sufficiently before resuming duties. The chosen time frame from _8:00 PM_ to _4:00 AM_ is designed to coincide with the typical night rest period, promoting circadian rhythm stability and mitigating the effects of fatigue during subsequent flight duties.
Option _c)_ meets the criteria for a Split Duty Trip rest period by providing a scheduled and actual rest period of at least _8 hours_, aligning with the specified time range of _8:00 PM_ to _4:00 AM_. This adherence to regulatory standards ensures the safety and optimal performance of flight crew members.
