Use cases and requirements

4.20 Information for regulatory purposes

Description Collect, analyse and store (tamper-proof collection of flight data) systems-related aircraft data.
Scenario The pertinent data from the aircraft can be obtained for analysis for regulatory report-
ing purposes.

User groups • CAA, FAA, EASA;
• Crew training;
• Maintenance/MRO.
Benefit • Improved flight operations;
• High reliability for A/C dispatch;
• Accurate aircraft information for mandatory reporting to regulatory authorities.
Required data • All fuel-related data, APU-related data, engines-related data – fuel consumption, OOOI
times, slat/flap data, etc.

Data sources • QAR;
• DFDR.
Special considerations Data security, integrity and reliability.

Amount of data Very nominal payload.

Transmission interval Post-flight.
Transmission technologies VHF, satellite, WiFi, WGL, GSM. The protocols are typically ACARS, SatCom and IP based.

4.21 Mission support

Description In-flight support for the flight crew from ground. The mission support team is usually part of
the flight operations centre. They assist by tracking the flight, monitoring bad weather areas,
awareness of special airport information, etc. With flight data being available in real time, the
mission support team can know the technical status of the aircraft. Technical problems can
be detected early and support from ground will be available. The members of the mission
support team itself are typically not technical experts. The analysis will be done by the trou-
ble-shooting team from the maintenance department.

Scenario A flight is being monitored from the mission support team. An in-flight engine shutdown
occurs. This is automatically reported to the ground system, together with monitoring and
flight data. The incident is being reported to trouble-shooting for technical analysis and the
mission support team evaluates diversion airports, fuel quantity, etc.
User groups • AOC/central dispatch.

Benefit • Real-time awareness of aircraft situation;
• Quick reaction times;
• Information on aircraft and flight status without pilot communication.

Required data • Flight data, monitoring data.

Data sources • FDR/QAR;
• ACMS/CMC system;
• Systems for passenger/crew or cargo monitoring.

Special considerations Data security, integrity and reliability.
