What do ETD and ETA stand for?

• A. Electronic Time of Departure and Arrival.
• B. Estimated Time of Departure and Estimated Time of Arrival.
• C. Estimated Time Delivered and Arrival.
• D. Enhanced Tracking of Devices and Aircraft.

Answer: (B)

ETD and ETA are the predicted times used in airline operations to plan movement and inform passengers. ETD stands for Estimated Time of Departure, and ETA stands for Estimated Time of Arrival. They’re forecasts that can change as conditions shift, helping ground crews coordinate gate availability, pushback, connections, and updates to passengers. The other options use terms not employed in aviation—Electronic Time, Delivered, or Enhanced Tracking—so they don’t match how these timings are described in practice.
