Flight Leg Status

A high level status of a FlightLeg from an Airport perspective.

• "SCH” - Scheduled
  The initial state for a scheduled Flight.
  A flight leg that is expected to depart and land according to the available information.
  Can transition to: FPL, OBK, CAN

• "FPL” - Flight plan
  Initial state for a FlightLeg that isn’t scheduled.
  The flight plan has been filed and is registered by AirTrafficManagement. 
  Can transition to: FLS, SEQ, OBK, CAN

• "FLS” - Flight suspended
  The FlightLeg has been suspended by AirTrafficManagement, but can be activated at any time. 
  Can transition to: FPL, CAN

• "SEQ” - Sequenced
  The FlightLeg has been sequenced by AirTrafficManagement. 
  Can transition to: OBK, CAN

• "OBK” - Off-block
  The Aircraft is OffBlock, but not airborne.
  Can transition to: AIR

• "AIR” - Airborne
  The Aircraft is airborne.
  Can transition to: FIR, FNL, LAN

• “FIR” - In destination Flight Information Region
  The Aircraft is in the FIR that cover the destination airport.
  Can transition to: FNL, LAN

• “FNL” - Final approach
  The Aircraft is on the final approach for landing.
  Can transition to: LAN

• "LAN” - Landed
  The Aircraft has landed.

• “IBK” - In-block
  The Aircraft is InBlock.
  End state.

• "CAN”
  The FlightLeg has been cancelled. 
  End state.

• "DEL”
  The FlightLeg appears to have been deleted/removed.
  This is probably the result of missing schedule change information or some other data errors.
  End state.

• "UKN”
  Unknown indicates missing information.

Other statuses might be defined at a later stage. System specific values are allowed, but please use 4 characters.

Which statuses and transitions that actually are used are system dependent. Other transitions than the ones listed might be allowed by a system, and might be necessary due to limited data.

A transition to “DEL” (if used) and “UKN” can in theory happen from all states.

• "UKN”
  Unknown indicates missing information. Usually this means that it’s time based when a state transition to unknown.

• "DEL”
  It is a matter of system design if this state is used. Deleted flights can be physically deleted (in databases), but they can also be marked as deleted and become "invisible". If “DEL” is used as a status then it is set when information arrives that explicitly deletes the flight leg, or when it can be deduced that it is an erroneous entry that should be deleted (ghost flights for instance).

• "CAN”
  A cancelled flight will often not be deleted, but only marked as cancelled. There are IATA messages that can cancel a flight (leg) and then reinstate it later.
