What is Zulu time and why do pilots use it?

Zulu time is the aviation term for Coordinated Universal Time (UTC), the global time standard used by pilots, controllers, and dispatchers worldwide. It eliminates timezone confusion when crossing time zones or coordinating with ATC facilities in different regions.

All METARs, TAFs, NOTAMs, flight plans, and ATC clearances use Zulu time. When a METAR says "231456Z," that means the 23rd day of the month at 14:56 UTC. Pilots must convert between local and Zulu time constantly during preflight planning and in-flight operations.

The letter "Z" comes from the NATO phonetic alphabet designation for the UTC+0 timezone — "Zulu." This convention has been used in military and aviation operations for decades to avoid ambiguity.
