If a flag air carrier flight lands at an intermediate airport at 1805Z, what is the latest time it may depart without redispatch?

To determine the latest time a flag air carrier flight may depart from an intermediate airport without needing to be redispatched, it is important to understand the regulations governing flight operations, particularly those applicable to flag carriers. A flag airline is subject to specific rules regarding flight durations and planning.

According to FAA regulations, the flight must be able to continue its journey within a specific time frame following its arrival at that intermediate airport. The key regulation stipulates that for a flight that lands, the flight can use the calculated flight time to determine the boundary of its subsequent departure window.

Given the information that the flight lands at 1805Z, we must consider the typical maximum time limit allowed without needing a redispatch. For flag carriers, this time limit is generally established based on operational needs and regulatory requirements. In many cases, this limit is often set to 6 hours after the flight's landing time.

Calculating 6 hours after 1805Z results in a departure time of 0005Z the following day. This aligns with regulatory practices, ensuring that the carrier adheres to safety and planning protocols.

Therefore, the latest time that the flight may depart without redispatch is indeed 0005Z. This conclusion is consistent with safety regulations governing operating
