Use cases and requirements

can be established, from which an array of benefits can be derived by airline flight safety, flight operations and
maintenance departments and other user groups. When combined with the real-time transmission of flight
data, this environment is also able to host functionality that meets the requirements for flight tracking, which
is an element of the global aeronautical distress and safety system (GADSS) as described by the International
Civil Aviation Organization (ICAO). It is the opinion of Working Group 2 that cloud computing has more potential
than traditional GDRAS systems for the introduction and integration of datasets from additional data sources.
Consequently, there is greater potential for cloud computing to generate additional value and benefit as a
result of the processing and analysing of data from additional datasets along with traditional flight data and
the visualization of new information derived from those analyses in new and useful ways.

2 Use cases overview and user groups

2.1 Use cases overview

Working Group 2 has identified use cases for flight data tracking. This section presents an overview of the
uses cases, while section 4 describes them in detail. The use cases are categorized in terms of their relevance
to flight data streaming and the potential for selected parameter data being used in real time for new and
valuable purposes:

Category A – High priority for real-time transmission of relevant parameters within flight streaming.
Category B – Low priority for the transmission of relevant parameters within flight streaming.

Table 1 identifies the high and low categories of use cases.

No. Use case Category Comment Section

1 Search and rescue A - High The task of tracking an aircraft for supporting search 4.1
and rescue operations by providing the last known
aircraft position and trajectories of likely aircraft
movement after the last reported position.
2 Flight tracking A - High The task of tracking an aircraft for the purpose of 4.1
determining its real-time spatial location or post-
flight track flown.
3 Accident investigations A - High Analysis of flight data immediately after an accident, 4.10
before the flight data recorder (FDR) is recovered
and read out.
4 Mission support A - High Real-time situation awareness of aircraft condition 4.21
for flight operations department.
5 Air traffic control (ATC) A - High Provide real-time instantaneous aircraft departure, 4.3
arrival and en-route information to ATC.

6 Ground movement/handling A - High Provide real-time instantaneous aircraft departure, 4.4
arrival and en-route information to airports.

7 Trouble-shooting A - High Collect, analyse and store aircraft systems, engines 4.5
data for detection and analysis of failures.

8 Crew scheduling A - High Provide real-time instantaneous aircraft departure, 4.6
arrival and en-route information to airline opera-
tional communication (AOC) and crew scheduling.
