Which is the correct expansion for ETA?

• A. Emergency Time of Arrival
• B. Estimated Travel Arrival
• C. Expected Time of Arrival
• D. Estimated Time of Arrival

Answer: (D)

Understanding timing abbreviations used in aviation helps you see why this one fits. The standard expansion for ETA is Estimated Time of Arrival. This wording signals a forecast based on current flight data—speed, winds, route, and other factors—and it can change as conditions evolve. The other phrasings aren’t used in typical aviation practice: Emergency Time of Arrival isn’t a recognized term, Estimated Travel Arrival isn’t a conventional wording, and Expected Time of Arrival isn’t the standard expansion, even though it may sound similar. So the accepted and widely understood form is Estimated Time of Arrival.
