"A-SMGCS functions

When authorized by and subject to conditions prescribed by the appropriate ATS 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;

Note.— Where visual observation by the aerodrome controller is not possible, or whenever deemed beneficial by the aerodrome controller, the information provided by A-SMGCS may be used to replace visual observation.

b) monitoring 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";
