    Hal Raju himself said, IAF has to allow metal cutting for FOC aircrafts to be able deliver 20 crafts by 2022.

    That's why there is no hurry for ordering engine of Mk1A.

    My guess is FOC is nowhere in sight .. Otherwise IAF might have already allowed metal cutting.

    I am just hoping France would be awarded to upgrade the aircraft itself.

    Again update yourself, the ASQR for the MK1A is not finalized nor issued, so without that leave aside any production.

    So let's focus on the FOC, and full scale development on the MK2.

    MK2 will be only after MK1A right ?
    but development gets started ahead of Mk1a ?

    Design changes can be started independent from MK1A, since 1A is based on the old MK1 airframe. These changes later will be included in the MK2 again.
    However, MK2 will also include changes that IAF feels needed after having operational experience with LCA and that can only come after FOC is inducted and at least some MK1A pre series versions for tests are available.

    PVC recipient Sekhon’s squadron to fly again
    http://www.tribuneindia.com/news/nation/pvc-recipient-sekhon-s-squadron-to-fly-again/502125.html

    Coinciding with the golden jubilee of the commissioning of IAF’s only Param Vir Chakra recipient, Flying Officer Nirmaljit Singh Sekhon, the Air Headquarters has drawn up plans to revive the squadron that he had served in. The squadron will be re-formed on the indigenously-built Light Combat Aircraft Tejas.


    Sekhon’s outfit, No. 18 Squadron, also known as Flying Bullets, had been de-commissioned or “number-plated”, as it is called in Air Force terminology, two years ago after the MiG-27 aircraft that it was equipped with were decommissioned.

    “We met Air Chief Marshal BS Dhanoa this week and he told us that the IAF is making sure that Sekhon’s contribution to the nation and the force is never forgotten,” Air Marshal AK Singh, former Air Officer Commanding-in-Chief, Western Air Command, who is Sekhon’s batchmate, said. “The process of revising the war hero’s squadron is part of this endeavour,” he added.

    The squadron was formed on April 15, 1965, with Gnat fighter aircraft. It first saw action during the 1971 Indo-Pak war and operated out of Srinagar with the task of defending the Kashmir valley. Sekhon, then just 28 and hailing from Ludhiana, was part of the deployment. On December 14, 1971, Sekhon, along with another officer, scrambled to counter an attack by Pakistan aircraft and shot three enemy Sabre jets in aerial combat. His own aircraft was hit and he went down. For his actions, he was decorated with the highest gallantry award.

    After the war, the Gnats were replaced with HAL Ajeet in 1975. In May 1989, when the squadron was at Hindon, it received the MiG-27 and its role changed from air defence to ground attack. It then moved to Kalaikunda in the North-East, where it was awarded the President’s Standards in 2015 before flying into the sunset.

    Several of Sekhon’s batchmates from the 97th Pilots’ Course, who were commissioned in June 1967, had met the IAF chief and presented him a plaque dedicated to Sekhon that would be displayed in the Air Force Museum at Palam.

    Reviving the squadron, however, could take time as new aircraft are yet to come in. Last year, the IAF had raised its first Tejas unit, No. 45 Squadron, the Flying Daggers, to be based at Salur in Tamil Nadu, but it has just a handful of planes and is not fully operational.

    The Engine Exhaust Nozzle of India's Light Combat Aircraft Tejas.
    A propelling nozzle converts a gas turbine or gas generator into a jet engine. Energy available in the gas turbine exhaust is converted into a high speed propelling jet by the nozzle. Turbofan engines may have an additional and separate propelling nozzle which produces a high speed propelling jet from the energy in the air that has passed through the fan. In addition, the nozzle helps to determine how the gas generator and fan operate as it acts as a downstream restrictor.

    Can we not add wingtip weapon stations to the tejas, by making modification to the wing tips? Like we have in Rafale.

    yes, change the complete wing, re do the CFD and wind tunnel analysis and start the whole exercise all over again for next 33 years.
    To add wingtip missiles to LCA, you will need some tip chord and strength to with stand the loads of the missile. Just to tell you, a missile like R-73 with its rail is about 150kgs. Now multiply it by 13.5 times and that is the minimum strength you will need at the tip of the wing.

    Do you really think that there is enough space to support wingtip pylon?
    Almost the complete wing tip is a moving part i.e. Ailerons and no wingtip surface is available to fix a pylon.
    And if we cut some portion of Aileron and made it the part of wing (static) than it will reduce jets agility.

    I guess then the only option would be to resign the fuselarge, so that we can add pylons in the belly. I seriously hope we develop multiple ejector racks for the available pylons. Sure they would add drag, but at least would help them carry considerable fire power. Guess this is the only option for MK1A. ( Multiple ejector pylon - dual/tripple).

    or Over Wing missile like in jagaur

    Especially useful for low flying missions, where missiles over wing have ability to fly upwards to tackle any interceptor threat while undergoing ground hugging missions.

    Mk2 is the naval variant for LCA for carrier operation. IAF still not committed to mk2, and mk2 is been developed by ADA, while Mk1A by HAL.

    I don't think there is any kind of complexity left over to achieve FOC - just the IRF probe and the Gun. These are not complex fitments, but are simply time consuming in terms of step-by-step testing.

    Seems easy, but is not e.g first for the IFR probe ---- installation and plumbing internal connection is easy part but difficult is the testing and validation part with life threatening and the life of the project involved thus ADA is over cautious and also they don't have the experience. Pls note that the negative notion and import lobbyist are just waiting for a single mishap, than flood the media, political environment to dump the whole project. Second the Gun integration would need extensive testing and the study of the effects on the flight due to the vibration and shocks due to staffing gun fire at various altitude, and speed and also the effect of the smoke ingested by the engine intake.

    Best should be the SAAB approach, and hire the expertise service for testing validation and certificate, from BAE or Dassalt. I won't mind some time, rather than some mishaps.
