Aircraft digital flight-control: GE turbofan aircraft engine 10/10

The original plan was for the LCA prototype Tejas aircraft to be equipped with the General Electric  or GE F404-GE-F2J3 afterburning turbofan engine, while the production aircraft would be fitted with the indigenous GTRE GTX-35VS Kaveri turbofan being developed in a parallel.

Continued development of aircraft snags with the Kaveri resulted in a 2003 decision to procure the upgraded GE F404-IN20 aircraft engine for the eight pre-production LSP aircraft and two naval prototypes and after accelerated trials an order was placed for 24 more IN20 airplane engines for installation on the first 20 production aircraft. The Tejas Mark II will be equipped with the more powerful GE F414engine.
