Which time standard used in aviation is roughly GMT equivalent?

• A. Pacific Standard Time
• B. Central European Time
• C. Greenwich Mean Time
• D. Local Time

Answer: (C)

In aviation, operations rely on a single universal time reference to avoid confusion across time zones. The standard used is Coordinated Universal Time, which is essentially the same baseline as Greenwich Mean Time. So Greenwich Mean Time is the option that matches GMT most directly. Pilots and air traffic controllers often refer to it as UTC or “Zulu time,” reinforcing its global consistency. The other choices are regional times (Pacific Standard Time, Central European Time, Local Time) that shift with daylight saving or depend on location, making them unsuitable as a universal reference for flight schedules.
