.
An identification function shall ensure that communications can take place only between authorised flight message transfer peer entities;
.
A connection management function shall establish and release connections between flight message transfer peer entities ensuring that flight data transfer can be achieved only during the lifetime of a connection;
.
A data transfer function shall send and receive flight data messages between connected flight message transfer peer entities;
.
A monitoring function shall verify the continuity of service of a connection between flight message transfer peer entities; and
.
All functions exchanged between flight message transfer entities shall use Transmission Control Protocol over Internet Protocol, IP version 6.
6.7 Reference Material

7 Clocks
7.1 A clock which is easily visible from each control position is to be provided (206). UTC shall be shown in hours, minutes and seconds (207) and is to be accurate to within ±15 seconds per day (208).
7.2 Each control position should have a clock (209).
8 Aeronautical Ground Lighting (AGL) Control and Monitoring Equipment
8.1 Definition
Aeronautical Ground Lighting (AGL) is defined as ‘Any light specifically provided as an aid to air navigation, other than a light displayed on an aircraft.’ (ICAO Annex 14).
8.2 Scope
This section refers to Aeronautical Ground Lighting installations at licensed aerodromes only.
8.3 Safety Objective
The AGL Control and Monitoring System shall enable the selection of the required display of lights and provide an indication of the lights displayed to the aerodrome control position.
8.4 An indication, easily visible from the aerodrome control position(s), showing the actual serviceability status of AGL services (as opposed to the switch position), shall be provided (215). The equipment shall indicate when failure or abnormal operation of the AGL service selected for use falls below levels required by the aerodrome licence (216). These levels are outlined in CAP 168.
8.5 Modern AGL equipment is capable of providing highly detailed system performance information. The serviceability status information required to be passed to pilots shall be readily established from the indications visible from the aerodrome control position(s) (217).
