Aviation's Use of Zulu Time Explained as Radio Communication Standard

Pilots and controllers worldwide share a distinct communication system. The terminology they transmit over radio frequencies is not informal shorthand. It is an engineered system built over decades, designed to be understood clearly by any pilot or controller, whatever their native language, the radio quality, or the countries involved. Every term in it exists to solve a specific problem. Zulu time is one such term, used instead of UTC, but the source does not explain the reason for this choice.
