India's first military flight using blended bio-jet fuel flown by IAF

On 17 December 2018, Experimental Test Pilots and Test Engineer from IAF's premier testing establishment ASTE, flew India's first military flight using blended bio-jet fuel on the An-32 transport aircraft. The project is a combined effort of IAF, DRDO, Directorate General Aeronautical Quality Assurance (DGAQA) and CSIR-Indian Institute of Petroleum.

On 27 July 2018, Air Chief Marshal BS Dhanoa, Chief of Air Staff had announced IAF's intention to promote biojet fuels. Addressing the CII-SIDM seminar on promoting indigenised technologies, the CAS had stated that IAF intended to fly the An-32 with 10% biojet fuel on 26 Jan 2019 Republic Day flypast.

Indian Air Force carried out extensive engine tests on the ground. This is now followed by flight trials using 10% biojet blended ATF. This fuel is made from Jatropha oil sourced from Chattisgarh Biodiesel Development Authority (CBDA) and then processed at CSIR-IIP, Dehradun. IAF intends to fly the An-32 transport aircraft using biojet fuel on 26 January 2019, in the Republic Day flypast.
