JetBlue Basic Airline Terminology Practice Test

Which statement describes Zulu Time?

It is used only in military airspace. It is the time used for flight plans only. It is roughly equivalent to GMT. It is the aviation term for Coordinated Universal Time (UTC).

Correct Answer:

It is the aviation term for Coordinated Universal Time (UTC).

Explanation:

Zulu Time is the aviation term for Coordinated Universal Time (UTC). This standard is used across all flight operations to keep times consistent worldwide, regardless of local time zones or daylight saving. It isn’t limited to military airspace or to flight plans alone; weather reports, air traffic control, navigation logs, and departure/arrival times all use Zulu time. Some people think it’s the same as GMT, but in aviation the precise reference is UTC, and Zulu time corresponds to UTC rather than just being “roughly GMT.” This universal time ensures clear, synchronized communication and coordination worldwide.
