Looking at the documentation for FlightXML v2 Push callbacks, it seems like some change events are triggered for values that are not present in the payload. Gate changes, for instance is not present in the payload documentation, but it is mentioned that gate changes would trigger an alert.
I have two questions:
There’s an exhaustive list of the changes the ‘change’ callback type refers to?
There are some flight info data that seem to be only present in FlightXML v3 (TailNumber for example). Would a change in of the assigned tail number trigger a ‘change’ alert?
