Yes this is an old news and i do not know update.
RTA-70 Project is in pre-primary stage. They are carrying out studies after this they will ask for funds. NAL is also considering Pratt and Whitney turbo-prop engine for the plane. It will minimum take decade(or more) before we see first prototype. All this depends on success of Saras which is their primary focus.
Once a manufacturing starts here, it will be very economical and low cost will drive the sale of make in india planes.
Is there any update on this project ?
If NAL is still serious about elongated --25-30 seater-- version of SARAS then it might consider Fly By Wire and side stick controls.
So, Its a Russian design after all ..
JSC "Experimental Machine Building Plant named after V. Myasishcheva "(EMRs them. Myasishcheva) modernizes aircraft Saras. Plane created by Indian designers project-based M-102 ("Duet").
I understand the fly-by-wire part but why a sidestick? Electronic stick inputs can come from both a yoke as well as a sidestick.
China has Shenyang and chengdu aircraft corporation, Russia also has Sukhoi and mikoyan, USA has Boeing and Lockheed Martin. All these companies manufectured, produced and competed for each other respective fighter aircrafts. The famous competitions between american fifth gen fighter aircraft design between Boeing and Lockheed Martin is well known and of which the later won (f22). Same is the case of Russia and china. All these competing aerospace companies also manufectured parallel 4th and 4++ generation fighters aircraft. That means that there is a healtthy competetion between themselves within their own respective country's requirement as well for export. All these companies have independent R&d unit. But an intriguing question is "Why not India"? Or Why not Hal and NAL do the same for India? In India lack of planning and vision, political and beurocratic red tapism and trade unionism among the DPSUs employees and lack of corporate culture etc are some of the reasons/factors hindering civilian or military aircraft development and manufecturing in India. We should discard "Chalta hein" or "others also don't do it" attitude, rather we should be innovative and embark on massive r&d effort. But how much of our GDP is invested in r&d sector? How many indians are patent holders?
Not much in terms of technology but aesthetics. Since it is a commercial aircraft a look similar to those of Airbus's and Boeing's will matter commercially.
Boeing aircraft have control yokes. Airbus has sidesticks. Both are fine either way. Some pilots swear by the yoke. Others by the sidestick.
Future of CAS maybe drones and artillery. In permissible environment, propeller planes will be enough.
The world is still experimenting with both and even combinations of both.
The only problem in design of Saras it seems is conversation to a sea plane because of low wings.
NAL starts taxi trials of improved Saras
Saras, one of the first attempts at making small, short-haul planes in the country, is rolling on its wheels after eight years, warming up before it tests its wings again.
A modified prototype of the 14-seater transport aircraft started making low-speed taxi trials in early August. Air Force pilots have completed five runs of around 45 minutes each and will next move on to high-speed taxi tests, according to Jitendra Jadhav, Director, National Aerospace Laboratories, under the Council for Scientific & Industrial Research (CSIR).
Dr. Jadhav said, “We plan to fly the aircraft in the first week of October after the high speed taxi trials are completed. We made more than 10 modifications since the accident. The performance of the plane’s systems after the modification will be evaluated during the flights.”
About 25 flights are planned in the first set of the modified prototype, the PT1N, he recently told The Hindu. By the end of 2019, NAL plans to fly a production-standard version for air-worthiness certification.
Except for minimum maintenance engine runs, the 14-seater aircraft has not taxied or flown since one aircraft version crashed near Bengaluru in 2009 killing all three crew members. In February this year, the Minister of Science & Technology — in whose purview NAL and other CSIR labs fall — said the government was intent on completing the plane’s development and making it flight worthy.
The revival activities started with five ground-runs of its two Pratt & Whitney engines followed by the taxi trials. A few more LSTTs [low speed taxi trials] are due.
The 10-odd modifications were made to make it more pilot-friendly, agile, or easy to control; and to enable it to fly higher. The final Saras is planned to be able to cover 1,600 km at a maximum speed of 425 kmph, have a service ceiling of 9-10 km and fly continuously for five hours.
Dr. Jadhav outlined the roadmap: "After the trial flights, the design configuration of Saras is targeted to be frozen by March 2018 as production standard. By then we should have reduced the weight and drag issues. We would have made improvements in avionics, glass cockpit, environment control systems, cabin pressure control systems and a few changes in flight control systems. We then go in for funding [from the government] for two limited series production vehicles and a static specimen.
"The current plan is that we start flying the LSPs by December 2019 for final certification," he said.
When ready, Saras, initiated in 1999 as a civil light transport plane, will first get certified for military use. The Indian Air Force has indicated a need for 15 of them. A civil variant is to follow.
Full-scale production is scheduled to be taken up in 2020 at the Kanpur facility of Hindustan Aeronautics Ltd - where HAL produces its Dornier-228 transport aircraft.
The project has used up around ₹ 500 crore. Dr. Jadhav said, "We need around ₹ 550-660 crore to produce two LSP versions. We will move the necessary papers after the first flight."
Why no news on RTA?
Hope that they start developing RTA in parallel with Saras. RTA is being designed for both civil and military use, so it would be a good replacement for the An-32 fleet. If Saras LSP start arriving in 2019, and if they delay RTA development till then, we might not be able to create a RTA military version in time for An-32 replacement.
Why HAL and ADA are not competing? Cause they are collaborating.
Rivals join forces to develop Indian aircraft
Link doesn't open. Can you please post the link again?
NAL is an independent entity supposed to be doing fundamental research on aerodynamics & its facilities are open on an equal footing to all DPSUs & private-sector companies. There is thus no need for it to be part of any industrial entity. But when NAL tries to get its hands dirty with work that HAL is supposed to do (like developing the Saras), it ends up with failures because these are jobs meant for engineers, & not scientists
In case it still does not work, try searching (with check box "search title only" ticked) the following title on the forum:-

Meanwhile TAC OO5 is preparing for first flight.
India’s First 19-seater aircraft may fly soon

MUMBAI: A team of engineers is giving shape to what promises to be India’s first 19-seater indigenous passenger aircraft at a 3,000-sq feet terrace in Mumbai’s Borivili suburb, which has become a bustle of activity. Amol Yadav, a pilot with a private airline, is leading the initiative.
TAC 005, as the aircraft is called, will be ready for flight in the next four months, and is likely to give shape to India’s dream of a homegrown passenger aircraft.
Yadav said that he began work on the 19-seater aircraft to solve India’s regional connectivity issues. “In spite of having a number of private airlines, we are poor in regional connectivity. The smallest aircraft that private airlines in India have are 70-seaters, and they don’t find it cost-effective to fly them to smaller cities as they are never full.”
Yadav’s 19-seater aircraft is likely to change that situation by giving airlines and people an option of flying in a smaller plane. India hasn’t been able to build its own passenger aircraft even 70 years after independence. TheNational Aerospace Laboratories (NAL) had tried to build Saras, a 14-seater aircraft, but the plan had to be abandoned after the prototype crashed in 2009. NAL has recently revived the programme.
The structure of the twin-engine turbo prop built by Yadav — ET had exclusive access to the aircraft — is ready and will be powered by a Pratt & Whitney PP6A engine.
Any update on this one guys?.........…...........
