Which time standard is used to denote Zulu Time?

• A. Local Time
• B. Pacific Time
• C. Coordinated Universal Time
• D. Greenwich Mean Time

Answer: (C)

Zulu Time is the aviation term for Coordinated Universal Time. The letter Z is used to show zero offset from UTC, so 1200Z means 12:00 UTC. This standard keeps timing consistent across all time zones and ignores daylight saving changes, which is essential for global flight operations. Local Time and Pacific Time are specific time zones that vary by location and may observe DST, so they aren’t what Zulu Time denotes. Greenwich Mean Time is an older reference; modern aviation uses UTC as the precise standard, with Zulu just being the label for zero offset from that standard.
