If a flag air carrier airplane lands at an intermediate airport at 1822Z, what is the latest time it can continue its flight without redispatch authorization?

In this scenario, the question involves understanding the regulations surrounding flight dispatch and the timing related to an airplane's landing and subsequent departure. When a flag air carrier aircraft lands at an intermediate airport, it must be able to continue its flight within specific time constraints as defined by regulations.

The key factor to consider is the three-hour limit imposed after an aircraft lands at an intermediate stop. This regulation requires that a flight must either take off within three hours of landing or obtain redispatch authorization if it goes beyond that time.

Since the airplane lands at 1822Z, adding three hours results in 2122Z. However, the options provided are all earlier than this time. To find the latest time the airplane can depart without needing redispatch authorization, we simply take the landing time (1822Z) and add three hours, which indeed equates to 2122Z.

The choice marked as 0022Z (or 12:22 AM the following day in Zulu time) is actually the latest departure option under the three-hour regulation, as it reflects the time just past the three-hour window after the original landing time at 1822Z, leading to a misunderstanding regarding the prompt. The other times provided (1952Z,
