ITU-T Focus Group on Aviation Applications of Cloud Computing for Flight Data Monitoring
Use cases and requirements
User groups • AOC;
• Crew training;
• Maintenance/MRO;
• Airline/operator finance department.
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;
• AOC reports.
Special considerations Data security, integrity and reliability.
Amount of data Very nominal payload.
Transmission interval Performance criteria.
Transmission technologies VHF, satellite, WiFi, wireless groundlink (WGL), and global system for mobile communications
(GSM). The protocols are typically ACARS, SatCom and IP based.
4.8 Route planning and optimization
Description Collect (tamper-proof collection of flight data), analyse and store the aircraft position and
possibly additional data such as altitude, speed and heading. The route planning department
can analyse the data to improve the airline network, minimize costs, and increase passenger
satisfaction.
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.
The route planning department uses this data for optimization. Possible results can be
changes in the destinations, number of connections per week to a destination, used airways,
used aircraft model, etc. This is a continuous process, but the updates usually take place a
couple of times per year.
User groups • Air traffic management (ATM);
• Airport operations;
• 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.
