ITU-T Focus Group on Aviation Applications of Cloud Computing for Flight Data Monitoring
Use cases and requirements
Amount of data Depends on attached systems. If the flight data from the FDR/QAR are streamed, it is about
50 MB per long-range flight. Custom systems for cargo or passenger/crew monitoring might
require even more data to be transmitted.
Transmission interval Continuous streaming.
Transmission technologies Depends on the aircraft model and used system. Basically it can be anything: VHF, satellite,
WiFi, WGL, and GSM.
4.22 Abnormal movement of passengers and crew
Description State-of-the-art research works on aircraft systems that monitor the cabin areas. Abnormal
movement, such as fights, groups, running people, etc., can be detected by the system. A
report and possibly a video clip will be downlinked to the ground for further analysis.
Scenario During a flight, terrorists capture the flight. The terrorists carry weapons and overwhelm one
or two flight attendants. The situation is being detected and a report is sent to the ground.
The ground has an early notification of the situation and can continue to monitor the situa-
tion or assist the flight crew in their decisions.
User groups • AOC/central dispatch.
Benefit • Early notifications of assaults.
Required data • Video data, audio data, pre-processed reports.
Data sources • Custom video systems.
Special considerations Video streaming of the aircraft is something new in aviation.
Amount of data Unknown.
Transmission interval None for no abnormal detection.
Transmission technologies Satellite, cellular networks.
4.23 Flight planning
Description Collect (tamper-proof collection of flight data), analyse and store the aircraft position and
additional data such as altitude, speed and heading. This also includes the data while the
aircraft is on the ground. Other data of interest are door open/close time, boarding time or
catering, cleaning and fuelling times.
All this data can be used to optimize the events on the ground and in the air. For instance, the
passenger service routines can be updated or additional time on the ground can be foreseen
to avoid delays based on experience on that route.
Scenario The aircraft periodically transmits the own ship position to the ground. This happens without
interaction of the crew.
The ground system stores the data for later analysis.
On demand or on continuous improvement programs, this data gets analysed to update the
processes during flight for cabin and cockpit or the processes during pre-flight and post-flight.
User groups • Airline: AOC/central dispatch/flight control.
Benefit • Timely and instant availability of A/C situational awareness.
• Real-time information of flight status.
Required data • Minimum: Position, altitude.
• Additional: Speed, heading.
