• "Warning" - Some warning situation with the sensor. An warning code can be attached to the status, separated by a space.
  Example: "Warning 0x04000"
• "Error" - Some error situation with the sensor. An error code can be attached to the status, separated by a space.
  Example: "Error ERR-2043"

• "NotInReferenceDB" - The reference data does not exist in the used reference data database. For instance an unknown AircraftRegistration.

0 .. 9

• '0' - Not for public display
• '1' - For public display
• '2' - Should only be visible at the departure airport
• '3' - Should only be visible at the arrival departure airport

System dependent. For instance:

• ATM

• Airport

• Flight plan

• ReferenceData

• "TERM" - The flight will be terminated at the diversion airport.

• "01" - The UniqueFlightLegId was created. Typically used when a new FlightLeg has been created.
• "02" - The UniqueFlightLegId was added to the transaction. Typically used when a transaction is matched to an existing flight leg.
• "03" - The UniqueFlightLegId was updated. Typically used when a transaction includes a UniqueFlightLegId, but this matches a flight leg that has been merged into another flight leg.
• "04" - No UniqueFlightLegId "available". Typically when a transaction could not be matched to an existing flight leg, and could not be used to create a flight leg.
• "05" to "29" are reserved for future use
• "30" to "99" are reserved for airport specific codes

'0': No security issues with this flight leg.
