The Defence Bioengineering & Electromedical Laboratory, DEBEL in Bangalore, has taken a lead in developing an Integrated Life Support System, ILSS for fighter aircrafts. Dr W Selvamurthy of DRDO handed over the ILSS prototype consisting of 12 Line Replacement Units to Dr PS Subramanyam, Program Director of Tejas from ADA, for fitment and further trials into Tejas aircraft. An integrated life support system (ILSS) for fighter aircraft is a state of the art technology that enables a fighter pilot to venture to the limits of the aircraft capability. This technology had hitherto been the hallmarks of the few highly advanced countries. Now ILSS essentially performs the tasks of protecting the pilots against the extremes of altitudes, severe G forces imposed during aerial combats and also provide 100% oxygen in the case of ejection from aircraft. It is a unique technology that takes care of both single and dual pilot operations. The ILSS at a later date, can also be customized to the needs of other Indian aircraft capable of long duration flights like MiG-29, SU-30 and Mirage-2000.
