FlightInfoEx Updates in ETA

Hi there

Is the estimated time of arrival updated regularly when doing a query regularly on the same flight while it is in the air? Is there a general update circle in the ETA on FlightAware side?

Thanks
Andreas

ETAs are often updated over the course of a flight and can change between successive FlightXML requests. This data is generally provided by the operating airline or ANSP managing the airspace where the aircraft is operating.
