FlightLegIdentifier

This is the standard Airport Data Dictionary FlightLegIdentifier. None of the elements are required, but enough have to be present to actually uniquely identify a flight.

IFPLID	Defined by Eurocontrol as "A unique flight plan identifier, assigned by the IFPS". Two letters followed by eight digits.
callsign	A call sign is used to uniquely identify an aircraft using the airspace around a particular airport. Call signs in aviation are derived from several different policies, depending upon the type of flight operation. In most countries, unscheduled general aviation flights identify themselves using the call sign corresponding to the aircraft's registration number. Commercial operators, including scheduled airline, air cargo and air taxi operators, will usually use an ICAO or FAA-registered call sign for their company. These will typically consist of the ICAO code of the operating airline followed by a flight identification. The flight identification is very often the same as the flight number, but could be different due to call sign confusion, if two or more flights close to each other have similar flight numbers (i.e. KLM649 and KLM645 or BAW466 and BAW646).
aircraftRegistration	An aircraft registration is a unique alphanumeric string that identifies an aircraft. In accordance with the Convention on International Civil Aviation all aircraft must be registered with a national aviation authority and they must carry proof of this registration in the form of a legal document called a Certificate of Registration at all times when in operation. An aircraft can be re-registered in special cases, for instance if it's sold to an operator in another country.
ssrCode	Secondary Surveilence Radar Code A four-digit octal number received from the aircraft transponder when it is interrogated by a secondary surveillance radar (SSR).
flightId	IATA based identifier for this flight, usually issued long before the flight actually takes place. FlightId is normally the concatenation of OperatingAirlineIATA, FlightNumber and OperationalSuffix. FlightId typically identifies a flight to the majority of systems, but it is not unique across time. It's unique only in conjunction with FlightDepartureDate. Exception: Some airlines use their ICAO code (OperatingAirlineICAO) instead of OperatingAirlineIATA. This might be because they aren't an IATA member or because they just prefer the ICAO code. Regardless, this means that it is allowed to use OperatingAirlineICAO as part of FlightId. FlightId is then defined as the concatenation of AirlineIATAorICAO, FlightNumber and OperationalSuffix.
flightDepartureDate	The scheduled date (based on UTC) of departure of flight. For flights with multiple legs this is the departure of the first leg. This date must not change once set as it is used to make the FlightIds unique.
departureAirportIATA	Departure airport IATA code (see AirportIATA for description of term).
arrivalAirportIATA	Arrival airport IATA code (see AirportIATA for description of term).
departureAirportICAO	Departure airport ICAO code (see AirportICAO for description of term).
arrivalAirportICAO	Arrival airport ICAO code (see AirportICAO for description of term).

ResponseStatusCode indicates if the operation succeeded or failed, and if it failed - why. ResponseStatusText is a textual description of ResponseStatusCode. For all operations the set of response codes must be defined. The actual set is dependent upon the context.

"OK": Operation succeded.
"ERR01":
"ERR02":
"":
"":
"ERR99": Other error. "statusText" should describe the error.

Must be defined!

statusText : ResponseStatusText

A textual description of ResponseStatusCode.

TransData

CorrelationId	Identifier that can be used to correlate messages, transactions, log entries etc. The identifier should be unique across all relevant systems. It is the responsibility of the creator of the message/transaction/log entry/... to guarantee uniqueness. The CorrelationId can for instance be a GUID, or something shorter based on site specific rules.
SourceOrganization	Name of the organization/company that created the original data. This will typically be an airline company or an handler. The value set are site specific.
SourceTimestamp	UTC timestamp for when the source was updated. If unknown, use current (UTC) time.
