LCA Tejas: Indigenous Digital Flight Control Computer tested successfully


Indigenous Digital Fly by Wire Flight Control System for Tejas: In a major step towards achieving self-reliance in defence sector, Indian scientists and engineers have successfully integrated indigenously developed Digital Fly by Wire Flight Control Computer (DFCC) in prototype LSP7 on Monday (February 19, 2024). The digital fly-by-wire flight control computer has been developed by the Aeronautical Development Establishment (ADE), Bengaluru for the Tejas Mark-1A fighter jet.

Digital Fly by Wire Flight Control Computer features Quadraplex Power PC based Processor, high speed autonomous state machine based I/O controller, enhanced computational throughput and complex on-board software complied to DO178C level- A safety requirements. All critical parameters and performance of the flight controls were found satisfactory. The maiden flight was piloted by Wing Commander Siddarth Singh KMJ (Retd) of the National Flight Test Centre.
