| Wing Commander Chellappan Pillai Ratnamma Sreeji (20286) Aeronautical Engineering (Electronics), a graduate in Electronics and Communication Engineering from Madurai Kamaraj University, was commissioned in IAF on 04 Sep 89. In his 21 years of distinguished service, he held several important appointments such as Senior Technical Officer of a Missile Squadron, Senior Signal Intelligence Officer in a Wireless Experimental Unit, Senior Engineer (Electronics) of a front line fighter base before assuming charge as Joint Director (Trade Standards & Testing) at Air HQ. For his meritorious service, he was commended by AOC in C, WAC and VCAS in 2008 and 2010 respectively. As the Senior Signal Intelligence Officer posted to a WEU, he conducted several signal intelligence trials along the line of control, paving way to strategic relocation of one of its sub-units resulting in enhanced signal intelligence availability. As SE (L) at 35 Wing, he was instrumental in setting up AFNET ahead of the PDC with meticulous planning and close liaison with BSNL. His concern for optimum utilization of resources led to surrender of unused hired lines of BSNL resulting in annual saving of Rs.5 lakhs. Showing exemplary devotion to duty, innovation and initiative, he also undertook overhaul of arrester barrier at the base itself, which is otherwise a BRD level task, ensuring availability of arrester barrier for uninterrupted flying. Consequent to the frequent changes in the training patterns of airmen, the Airmen Promotion Examination (AIRPEX) system underwent major changes during the last three years. As JD Edn (TS&T) at Dte of Edn, the officer ensured smooth change over of the AIRPEX system. Nearly 40,000 airmen belonging to three different patterns of training (ATT, EPT and MPT) are now being flawlessly examined every year. The officer also initiated a case for rectifying the existing mismatch between Skill Grades awarded by the Examining Boards and the Annual Assessments of airmen. His proposal of linking the ACR with Skill Grades has been accepted and the revised policy is under issue. This policy is aimed at motivating airmen to go for higher skill grades there by improving the overall efficiency of the IAF. Further, to improve the efficiency of the AIRPEX system, he proposed for a yearly system against the existing half yearly system with substantial financial savings as well as large scale reduction in mass movement of personnel. The yearly system is scheduled to be introduced with effect from Jan 2011. Also, the Online AIRPEX system conceived by the officer is under implementation. For distinguished service of high order, Hon'ble President is pleased to award 'Vishisht Seva Medal' to Wing Commander Chellappan Pillai Ratnamma Sreeji.
