UTC expansion is which of the following?

• A. Unaccompanied Minor
• B. Unit Time Coordination
• C. Universal Time Code
• D. Cancelled

Answer: (C)

UTC stands for Coordinated Universal Time, the global time standard used in aviation and across many industries. It blends highly precise atomic time with occasional leap seconds to stay in sync with the Earth's rotation, ensuring a consistent reference for schedules, ATC clearances, and logs worldwide. Pilots and crews use UTC (often referred to as Zulu time) to avoid time-zone confusion during international operations. The option "Universal Time Code" isn’t the correct expansion—the recognized term is Coordinated Universal Time. The other choices don’t relate to the time standard used in flight operations. So the best understanding is that UTC = Coordinated Universal Time.
