With a sanction from the Cabinet Committee on Security, the Defence Research and Development Organisation is aiming to complete flight testing by 2027. has been told from the very start all aircraft will be of final operational clearance (FOC) standard that will help wind up developmental trials in less than 4 years from the time of first flight that has been planned in late 2023 or early 2024.

ADA is confident to meet the target deadline since most of the technology like On-Board Oxygen Generating System (OBOGS), Unified Electronic Warfare (EW) suite, Active Electronically-Scanned Array (AESA) radar, Digital flight control computer (DFCC), Radar Warning Receiver (RWR) already have been tested and certified even before the rollout of the first aircraft.

Hindustan Aeronautics and Bharat Electronics’ co-developed Infrared search and track (IRST) system is the only major system that is yet to be tested but it will be ready in time. Tejas MkII will be the first to feature sidestick controls, Large Area Touch based Displays, and a Smart head-up display that already has been developed and only waits for onboard testing on the aircraft.

ADA already has taken deliveries of a dozen GE-F414-IN56 engines that will power initial pre-production aircraft and efforts are being made to further indigenize critical avionics Line Replaceable Units (LRU) with help of HAL. Most of the developmental trials will be to validate many of the flight regimes of the aircraft in the first phase of the first two years and then move into weapons testing for the next two years.
