Communications Systems

on industry knowledge and experience (see Appendix 4 for the data volumes associated with flight
data recording standards).

A detailed description of the use cases are found in Deliverable 2/3.

The following examples of use cases were considered:
1. Flight tracking for safety and security (e.g. search and rescue, border protection);

2. Flight tracking for route planning and optimization (e.g. crew scheduling and fuel optimization);
3. Air traffic management (ATM) (e.g. air traffic control (ATC) including ground movement and
airspace optimization);

4. Predictive maintenance;
5. Inflight and post-flight trouble-shooting;

6. Reliability;
7. Accident investigation;
8. Flight crew techniques;
9. Approach statistics;

10. Original equipment manufacturers (OEMs) – Airframers and engines;
11. Meteorological purposes;

12. Cargo information;
13. Environmental efficiency;
14. Research and development (R&D) information;
15. Information for regulatory purposes.

It is assumed that these use cases remain valid for the foreseeable future. In accordance with its terms
of reference, WG4 focused on flight data monitoring for safety and security.

7.2 Definition of "real-time data"

For the purposes of this Report, "real-time data" is defined as data with adequate update rate and
latency to meet the operational requirement.

7.3 Categories of "flight data"

The following categories of flight data parameters were considered:
1. Navigational and trajectory data (e.g. position, altitude, speed, climb rate, attitude, etc.);

2. Engineering data (e.g. N1, (EGT), hydraulic line pressures, error codes, etc.);
3. Mission planning and identity information (e.g. call sign, flight number, flight plan, passenger
lists and cargo manifests, etc.).
