All times recorded on AMC Form 156 should be in what format?

The correct answer is Zulu time, which is also known as Coordinated Universal Time (UTC). Zulu time is critical for air transportation and military operations because it removes ambiguity related to time zones and daylight savings time. Using a uniform time format like Zulu time ensures that all parties involved in logistics, scheduling, and communications can coordinate effectively regardless of their geographic location. This consistency is particularly important in an international environment, such as air freight operations, where flights may cross multiple time zones.

In comparison, other time formats like local time or standard time can create confusion as they vary based on the region and can change with daylight savings. Military time is a 24-hour clock format, but it can still lead to misunderstandings without a common reference point, especially in multinational operations. Therefore, using Zulu time ensures clarity and precision in timekeeping for air freight operations.
