CSIR-NAL has already started design realization, life testing, and certification of Saras Mk2-19 seater aircraft, and the project is now heading towards detailed engineering and design. CSIR-NAL describes Saras Mk2 as Indigenous Next-Gen Commuter Transport Aircraft, which has utility to be used as local aircraft for the Government’s Udaan scheme for enhancing connectivity to remote and regional areas of the country.
IAF has committed to procure 15 aircraft for its fleet and CSIR-NAL sees demands for nearly 50-60 aircraft from the local regional airline companies once its enters production in 2025.
