In a noteworthy advancement for the Tejas Mk1A program, the prototype LSP7 successfully conducted a flight on February 19, 2024, following the integration of the indigenously developed Digital Fly by Wire Flight Control Computer (DFCC) by the Aeronautical Development Establishment (ADE) in Bengaluru. The DFCC incorporates a Quadraplex Power PC-based processor, a high-speed autonomous state machine-based I/O controller, enhanced computational throughput, and intricately designed on-board software compliant with DO178C Level-A safety requirements. All critical parameters and flight control performance were deemed satisfactory during the maiden flight, which was piloted by Wg Cdr Siddarth Singh KMJ (Retd) of the National Flight Test Centre.
The Aeronautical Development Agency, operating under the Department of Defence R&D and Ministry of Defence, has successfully achieved type certification for the Tejas-Light Combat Aircraft (LCA). The Indian Air Force has already put the Tejas LCA Mk1 into operational use. The upgraded version, Tejas MK1A, incorporates advanced features such as an advanced mission computer, a high-performance Digital Flight Control Computer (DFCC Mk1A), Smart Multi-Function Displays (SMFD), Advanced Electronically Scanned Array (AESA) Radar, Advanced Self-protection Jammer, and Electronic Warfare Suit.
Raksha Mantri Shri Rajnath Singh commended the collaborative efforts of the teams from DRDO, IAF, ADA, and industries involved in the development and successful flight testing of the critical system for Tejas Mk1A. He described it as a significant stride towards Atmanirbharata, contributing to a reduced reliance on special imports.
Secretary DDR&D and Chairman DRDO extended congratulations to the teams involved in the successful flight test, expressing confidence in the timely delivery of Tejas MK1A to the IAF.
