What does ETA stand for in aviation terms?

In aviation terms, ETA stands for Estimated Time of Arrival. This term is crucial for flight operations as it indicates the projected time at which an aircraft is expected to arrive at its destination. It takes into account various factors such as the flight plan, air traffic, weather conditions, and the aircraft's speed.

Estimating the time of arrival helps airlines manage schedules, coordinate logistics, and inform passengers and crews regarding flight progress. Airlines use this information to provide updates to those involved in the flight, ensuring that all parties are aware of potential delays or early arrivals. The accuracy of ETA can significantly affect airport operations and connecting flights.

The other terms presented do not align with standard aviation terminology. While they may sound relevant, they do not have recognized applications within the context of flight operations as ETA does.
