ATS.TR.245 Use of surface movement surveillance equipment at aerodromes

FUNCTIONS OF SURFACE MOVEMENT RADAR IN SURFACE MOVEMENT CONTROL The information displayed on an SMR display may be used to assist in:

(a)monitoring of aircraft and vehicles on the manoeuvring area for compliance with clearances and instructions;

(b)determining that a runway is clear of traffic prior to a landing or take-off;

(c)providing information on essential local traffic on or near the manoeuvring area;

(d)determining the location of aircraft and vehicles on the manoeuvring area;

(e)providing directional taxi information to aircraft when requested by the pilot or deemed necessary by the air traffic controller. Except under special circumstances, e.g. emergencies, such information should not be issued in the form of specific heading instructions; and

(f)providing assistance and advice to emergency vehicles.

FUNCTIONS OF ADVANCED SURFACE MOVEMENT GUIDANCE AND CONTROL SYSTEMS — A-SMGCS IN SURFACE MOVEMENT CONTROL When authorised and subject to conditions prescribed by the competent authority, the information provided on an A-SMGCS display may be used for the purpose of:

(a)determining the location of aircraft on the movement area and vehicles on the manoeuvring area. Where visual observation by the aerodrome air traffic controller is not possible, or whenever deemed beneficial by the aerodrome air traffic controller, the information provided by A-SMGCS may be used to replace visual observation;

(b)monitoring of aircraft and vehicles on the manoeuvring area for compliance with clearances and instructions;

(c)determining that a runway is clear of traffic or assisting in the assessment that a runway will be clear of traffic prior to a landing or take-off;

(d)providing information on essential local traffic on or near the manoeuvring area;

(e)providing directional taxi information to aircraft when requested by the pilot or deemed necessary by the air traffic controller. Such information should not be issued in the form of specific heading instructions (except in special circumstances, e.g. emergencies); and

(f)providing assistance and advice to emergency vehicles.
