Airlines progressing towards order management often stumble on the future of the Departure Control System. Boris gives a good summary on what needs to remain above the wing (exchange of passenger data with governments, readiness to fly of passengers, check-in of bags, etc.) and below the wing (weight and balance, etc.) – and what needs to change (connect to OMS instead of PSS, exchange data with API instead of EDIFACT, etc.).
The actual DCS question is: once we’ve implemented the order delivery module, which includes the data to governments, the passenger readiness to fly, the bag check-in, the seat assignments, etc., what’s left in a standalone DCS?
