Which term is the aviation label for UTC time widely used by pilots and controllers?
Correct Answer:
Zulu Time
Explanation:
In aviation, time must be the same for everyone no matter where you are, so all flight plans, weather, and ATC instructions reference a single clock. That universal time is UTC, and the aviation label for it is Zulu Time. The name comes from the NATO phonetic alphabet, where Z represents zero offset from Coordinated Universal Time. So, a timestamp like 1200Z means 12:00 UTC, not local time at the departure or destination. Using Zulu time avoids confusion during cross-border operations and when daylight saving changes. Other terms in the options relate to ground routes, passenger categories, or aircraft type, not time references.
