Performance checks – use of radar in area and approach control services – assurance control and co-ordination between radar / non radar control – emergencies

4. PERFORMANCE CHECKS Adjusting the radar display
Carrying out checks on the accuracy of the display as per ATC manual
Functional capabilities of the radar system is satisfied by the controller
If there is any difficulty in the peformance, it is reported

5. RADAR IDENTIFICATION
PSR Identification Procedures
SSR Identification Procedures

6. PSR Identification
By Departing Aircraft Method
By position report method-position
By Turn Method

7. PSR IDENTIFICATION
Departing Aircraft Method: By correlating an observed radar position indication with an just departed aircraft (within 1 NM of runway)
By position report method-position indication with an aircraft reporting its position
By Turn Method: An aircraft identified by ascertaining the aircraft heading

8. SSR IDENTIFICATION
Through a Call Sign or Code
By Direct recognition
By transferring Radar Identification to the pilot
By observation to a set of Codes

9. SSR IDENTIFICATION
Aircraft identification by a SSR Label thru a code/call sign
By Direct recognition of the aircraft identification of a Mode S-equipped aircraft in a radar label;
By transfer of radar identification
By observation of compliance with an instruction to set a specific code;

10. SSR IDENTIFICATION PROCEDURE
SSR transponder selected on Mode 3/A (4096 codes) and Mode C simultaneously
Pilots will maintain the same setting in the Transponder
ATC instruct the dep. Flight to operate the transponder 10
