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.).

8. Real-time data transmission performance

8.1 Introduction

There is a need to ensure consistent definition and use of data communication capabilities to apply the required
communication performance for a global data communications. This section provides a description of real-time
data and supporting data transmission performance. The material in this section referenced relevant ICAO
document 9869 AN/462 MANUAL ON REQUIRED COMMUNICATION PERFORMANCE (RCP). This Report has
drawn on this manual to set a baseline of possible real-time data communication performance.

This section examines examples of current communication performance standards relevant to navigation and
surveillance, and explores the data volumes and bandwidth requirements associated with real-time flight data
