                Required data            Various aircraft systems, engine systems data.

                Data sources             •  CMC;
                                         •  ACMS;
                                         •  Maintenance panel;
                                         •  QAR;
                                         •  DFDR.

                Special considerations   Data security, integrity and reliability.
                Amount of data           Very nominal payload.

                Transmission interval    In real time or during events such as top-of-descent or touch-down.
                Transmission technologies  VHF, satellite. The protocols are typically ACARS, SatCom and IP based.



               4.6    Crew scheduling

                Description              Provide real-time instantaneous (tamper-proof collection of flight data) aircraft departure,
                                         arrival and en-route information to AOC, crew scheduling.

                Scenario                 The pertinent data from FMC can be routed to AOC, crew scheduling using real-time systems.
                                         The airline can use the available real-time data to detect deviation from the schedule. The
                                         aircraft assignments of the crews can be updated accordingly.

                User groups              •  AOC;
                                         •  Crew scheduling;
                                         •  Airline/operator finance department.
                Benefit                  •  Improved flight operations;
                                         •  High reliability for A/C dispatch;
                                         •  Accurate aircraft information.
                Required data            •  Position reports.
                                         •  Any data that contains aircraft out, off, on, in (OOOI) times.
                Data sources             •  FMC;
                                         •  DFDR;
                                         •  AOC reports;
                                         •  ADS-B/ADS-C.
                Special considerations   Data security, integrity and reliability.

                Amount of data           Very nominal payload.

                Transmission interval    Performance criteria.
                Transmission technologies  VHF, satellite. The protocols are typically ACARS, SatCom and IP based.



               4.7    Fuel optimization

                Description              Collect, analyse and store (tamper-proof collection of flight data) fuel-related aircraft data.
                Scenario                 The pertinent data from the aircraft can be obtained for analysis to optimize fuel consump-
                                         tion, pilot techniques, and maintenance practices.
