Final answer:
The statement in question is false; Coordinated Universal Time (UTC) is indeed the standard time reference used in aviation to ensure global time coordination.
Step-by-step explanation:
The statement that UTC is not the standard time datum used in aviation is false. In aviation, Coordinated Universal Time (UTC), also known as Universal Time (UT), Greenwich Mean Time (GMT), or Zulu Time (Z), is used as the standard time reference. Pilots and air traffic control systems worldwide operate on UTC to facilitate coordination across different time zones. This 24-hour time system, without the division of a.m. and p.m., allows for a unified approach to scheduling flights and managing air traffic globally.
