Indigenous gas turbine based Air Producer Engine for Jaguar (AP-J) an engine starter was trial tested on test bed successfully by HAL. AP-J has been developed indigenously by HAL’s Aero Engine Research and Design Centre (AERDC), Bangalore.

The engine will be used to start main Adour Mk811 engines of the Jaguar after HAL and IAF started facing delays in spares supplies and was incurring high import cost resulting in AOGs (Aircraft on Ground) for the IAF.
