Use cases and requirements
4.9 Reliability
Description Collect, analyse and store (tamper-proof collection of flight data) aircraft data for technical
reliability of the aircraft.
Scenario The pertinent data from the aircraft can be obtained for analysis to predict systems and
mechanical failures proactively. The airlines and maintenance organizations continuously
monitor the dispatch reliability of the aircraft. Secondly, aircraft system engineers regularly
compile reliability reports of all aircraft systems to detect low performance of components or
maintenance processes.
User groups • Maintenance/MRO.
Benefit • Improved flight operations;
• High reliability for A/C dispatch;
• Accurate aircraft information;
• Fuel savings.
Required data All fuel-related data, APU-related data, engines-related data – fuel consumption, OOOI times,
slat/flap data, etc.
Data sources • QAR;
• DFDR;
• ACMS reports;
• CMC reports.
Special considerations Data security, integrity and reliability.
Amount of data Nominal payload.
Transmission interval When required.
Transmission technologies VHF, satellite, WiFi, WGL, GSM. The protocols are typically ACARS, SatCom and IP based.
4.10 Accident investigation
Description Collect, analyse and store (tamper-proof collection of flight data) aircraft data to assist acci-
dent investigation.
Scenario After an accident, the cause must be identified to prevent additional accidents. Depending
of the magnitude of the accident, the investigation can be done by the airline, maintenance
organization or authorities.
User groups • Flight safety;
• Safety boards;
• Flight operations;
• Maintenance/MRO.
Benefit • Post-accident analysis on a timely fashion. No need to find the black boxes.
Required data All fuel-related data, APU-related data, engines-related data – fuel consumption, OOOI times,
flight controls, slat/flap data, etc.
Data sources • QAR;
• DFDR;
• Voice data.
Special considerations Data security, integrity and reliability.
