5.6 Preparing and implementation of replacement
and up gradation proposal of CNS/ATM Data processing system.
5.7 Implementation of Safety Management System
(SMS) related to CNS and Automation facilities.
5.8 Disposal of obsolete CNS facilities proposal
received at CHQ from filed stations.
6.For smooth functioning, CNS-OM Dept is divided into following five
sections. Each section is headed by GM (CNS) who reports to ED (CNS-OM).
7. Brief details of functions/tasks performed by sections are as given
7.1) GM CRSD (Central Radio Stores Depot)
The Central Radio Stores Depot procures and stocks Spares / PCBs/ Modules/
Discreet Components of CNS equipment and provides them to the stations to
ensure the availability of CNS facilities. CRSD also arranges custom clearance,
Overseas & In-Land insurance and Re-Export of faulty systems during their
7.2) GM Communication (Com)
Regular Monitoring of Availability & Serviceability of Communication
systems at all airports/ACS. Provision of Aeronautical Mobile Services,
Aeronautical Fixed Telecommunication Network, VOLMET, Pre Flight Com Briefing
and International Notam Offices. Provision of Telephones, Fax & Mobile to
various AAI Units for operational and administrative requirements.
7.3) GM Automation and Surveillance (A & S)
Regular Monitoring of Availability & Serviceability of ATM Automation and
Surveillance systems. Human resource Management, Training and proficiency of
7.4) GM Navigation and CMC (Nav& CMC)
Regular Monitoring of Availability & Serviceability of ATM Navigation
facilities at all airports and ACS. Review of NOC cases from CNS point of view
received in CNS-OM Dept. CMC manages SMUs (Special Maintenance Unit) which are
established for different CNS equipment for complex component level repairs of
faulty modules received from different stations. At present SMUs are available
at Delhi IGIA and Safdarjung Airport, Kolkata, Ahmedabad, Hyderabad, Chennai
and Mumbai airports for different CNS/ATM facilities.
7.5) Functions of the Centralized Maintenance Cell
Department of Communication , Navigation & Surveillance (CNS) of
Airports Authority of India is responsible for operations and maintenance of
Communication , Navigation , Surveillance, Air Traffic Management (CNS-ATM) and
ancillary Systems for Air Navigation Services. To have high availability ,
reliability ,integrity and continuity of CNS/ATM facilities and optimum
operational use ,new maintenance philosophy has been adopted. The concept of
maintenance has changed with the rapid growth and advancement in the field of
electronics from the age old concepts of site maintenance to centralized repair
and maintenance .The present days technology of multi-layered PCBs and Surface
Mounted Devices require specialized tools skill and workbench to attend and
replace components. The equipment's design has also been made in the modular
concept ,enabling the identification / replacement as 1st and 2ed level of
maintenance at stations itself and reduce the downturn as minimum as possible .
The 3rd level of maintenance requires highly skilled and experienced personnel
to attend the modules at component level. All these tasks are being carried out
at Specialized Maintenance Units SMUs quiet efficiently and effectively. AAI
have established 20 SMUs for 12 facilities of different make and modules at
seven geographical locations of India.
