ITU-T Focus Group on Aviation Applications of Cloud Computing for Flight Data Monitoring
Key findings, recommendations for next steps and future work

1.25 data in motion (Deliverable 1): Data as it is in transit.

1.26 data at rest (Deliverable 1): Data stored in persistent storage (disk, tape).

1.27 data in use (Deliverable 1): Active data which is stored in a non-persistent digital state typically in
computer random access memory (RAM), central processing unit (CPU) caches, or CPU registers.
1.28 decision tree learning (Deliverable 1): Uses a decision tree as a predictive model, which maps observations
about an item to conclusions about the item's target value.

1.29 digital asset profile system (Deliverable 1): Enable applications to interact with physical objects by a
unique identity for a physical object (e.g. an aircraft component) and associated information (e.g. performance,
maintenance) and maintain a record of its lifetime in operation (e.g. usage, quality, and value).
1.30 digital flight data acquisition unit (DFDAU) (Deliverable 4): An integrated system that combines the
functions of mandatory data acquisition and recording with a sophisticated aircraft condition monitoring
system (ACMS). This comprehensive system provides aircraft operators with a standardized hardware and
software solution for high-power data acquisition, management and recording to an internal Personal
Computer Memory Card International Association (PCMCIA) or magneto optical disk recorder.

1.31 digital flight data recorder (DFDR) (Deliverable 2&3): Device that preserves the recent history of the
flight through the recording of dozens of parameters collected several times per second. DFDR records a large
number of aircraft parameters in a highly robust unit. DFDR data is often called flight data.

1.32 flight data monitoring (FDM) (Deliverable 1, 2&3 and 4): General flight data analysis using various data
sources and technology solutions to solve the issues.

1.33 flight data streaming (Deliverable 2&3 and 4): Real-time transmission of various data from the aircraft,
some of which may be used for a variety of purposes including aircraft tracking, flight data recovery and
analysis in the event of an accident.

1.34 flight information display system (FIDS) (Deliverable 2&3): A computer system used in airports to display
flight information to passengers, in which a computer system controls mechanical or electronic display boards
or television (TV) screens in order to display arrival and departure flight information in real time.

1.35 flight management computer (FMC) (Deliverable 1, and 2&3): FMC is a specialized computer system
that automates a wide variety of in-flight tasks, reducing the workload on the flight crew. All FMSs contain a
navigation database.

1.36 flight operational quality assurance (FOQA) (Deliverable 2&3): A voluntary safety program designed to
improve aviation safety through the proactive use of flight recorded data. Operators will use these data to
identify and correct deficiencies in all areas of flight operations. Properly used, FOQA data can reduce or
eliminate safety risks, as well as minimize deviations from regulations.

1.37 flight tracking (Deliverable 1, 2&3 and 4): The task of tracking an aircraft for the purpose of determining
its real-time spatial location or post-flight track flown.
1.38 fog computing (Deliverable 2&3): Architecture that uses one or a collaborative multitude of end-user clients
or near-user edge devices to carry out a substantial amount of storage (rather than stored primarily in cloud
data centres), communication (rather than routed over the Internet backbone), and control, configuration,
measurement and management.

1.39 future air navigation system (FANS) (Deliverable 4): An avionics system which provides direct data link
communication between the pilot and the air traffic controller. The communications include air traffic control
clearances, pilot requests and position reporting. The FANS messages are sent over the aircraft communications
addressing and reporting system (ACARS) data links and networks. FANS applications include automatic
dependent surveillance-contract (ADS-C) and controller-pilot data link communication (CPDLC).
