Why Zulu Time Matters

Aviation worldwide operates on UTC (Zulu time) to eliminate confusion across time zones. Flight plans, NOTAM, METAR weather reports, and ATC communications all use Zulu. As a charter broker, always confirm departure and arrival times in both local and Zulu to avoid costly scheduling errors.

Pro Tips for Brokers

  • Always quote departure times in local + Zulu to clients
  • Watch for DST changes — they shift UTC offsets
  • International Date Line crossings can change arrival date
  • Crew duty time limits are calculated in UTC
