PRESENTATION AND UPDATING OF FLIGHT PLAN AND CONTROL DATA AND OTHER RELEVANT INFORMATION FOR THE AIR TRAFFIC CONTROL SERVICE PROVISION

(a)The air traffic services provider should ensure that sufficient information and data are presented in such a manner as to enable the air traffic controller to have a complete representation of the current air traffic situation within the air traffic controller’s area of responsibility and, when relevant, movements on the manoeuvring area of aerodromes.

(b)The presentation should be updated in accordance with the progress of aircraft in order to facilitate the timely detection and resolution of conflicts as well as to facilitate and provide a record of coordination with adjacent air traffic services units and control sectors.

(c)An appropriate representation of the airspace configuration, including significant points and information related to such points, should be provided.

(d)Data to be presented should include relevant information from flight plans and position reports as well as clearance and coordination data.

(e)The information display may be generated and updated automatically, or the data may be entered and updated by authorised personnel.

(f)Data generated automatically should be presented to the air traffic controller in a timely manner. The presentation of information and data for individual flights should continue until such time as the data is no longer required for the purpose of providing control, including conflict detection and the coordination of flights, or until terminated by the air traffic controller.

(g)All information and data as in point (a), including data related to individual aircraft, should be presented in a manner minimising the potential for misinterpretation or misunderstanding.
