ITU-T Focus Group on Aviation Applications of Cloud Computing for Flight Data Monitoring
Use cases and requirements

Benefit • Increase in A/C safety;
• High reliability for A/C dispatch;
• Reduced maintenance cost.

Required data Any data that contains technical information of the aircraft. This is a wide range of parameters,
e.g. engine data (gas temperatures at various stages in the engine, oil consumption, fuel burn,
rotation, vibration, etc.), flight controls data (actuator activities, movement durations, etc.),
fuel pumps data, environmental control system data, hydraulics, electrics, pneumatics, etc.

Data sources • ACMS reports;
• CMC reports;
• QAR data;
• Technical logbook.

Special considerations The QAR data provides many aspects of the situation and performance. It may require access con-
trol to the data because it can reveal sensitive operational and economical details of the airlines.
Assure data ownership, data privacy, data security and access control.
Amount of data ACMS, CMC and technical logbook reports are typically between 40 bytes and 10 kilobytes.
The number of reports depends on the events and A/C type; it can range from five reports up
to 40 reports per flight.
The QAR data today can be up to 100 MB per long distance flight.
Transmission interval Today some data, for example ACMS reports, is sent in real time. QAR data is typically down-
loaded post-flight.
Transmission technologies Very high technology (VHF), satellite, WiFi, 2G/3G. The protocols are typically ACARS and
Internet protocol (IP) based.

4.3 ATC

Description Provide real-time instantaneous aircraft departure, arrival and en-route information (tam-
per-proof collection of flight data) to ATC.

Scenario The air traffic controller uses the data of aircraft position, type, heading, etc., to manage the
airspace activities.
The pertinent data from FMC can be routed to ATC using real-time systems.

User groups • AOC;
• ATC.

Benefit • Increase in A/C safety;
• 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.
