### More about Estimated Time of Departure

ETD describes a current prediction rather than the original timetable. It can change as aircraft, crew, airport or weather conditions change.

It differs from scheduled departure time, STD. A departure estimate should also identify whether it concerns leaving the stand or taking off, because those are separate events.
