April 06, 2015: The LCA Tejas has completed hot and high & winter trials, including cold soak starting tests of its engine and ensuing flight performance. The success of the January 2015 tests allows the flight team to heave a sigh of relief given that there had been trepidation about full load trials at high altitude. According to ADA, "With three consecutive start-ups of its engine after overnight soak in extreme cold (around -15ºC) conditions of Ladakh, that too without any external assistance, Tejas, the Indian Light Combat Aircraft has achieved yet another and a rare distinction. Starting the fighter aircraft under such extreme condition without any external assistance or heating is a technology breakthrough. The requirements become further stringent when the starting is to be done three times consecutively with a partially charged battery. Team LCA led by AERD&C of HAL, and members from ADA, NFTC, IAF, CEMILAC and DGAQA have succeeded in achieving this.
