    OK here goes :-

    Q1.> Can the Tejas Mk.1 be said to have the most advanced avionics in the IAF after the Su-30 MKI ?

    Q2.> Will the first squadron of the Mk.1 be PERMANATLY based in Sulur, or will it be shifted to Phalodi in Rajasthan ? (as a newspaper report claimed once)

    Q3.> What is the combat radius of the Mk.1 with standard combat load ?

    Q4.> In terms of strike capability, will the Tejas Mk.2 be the equivalent of Gripen-NG and F-16 Block 52 ?

    Q5.> Is an AESA radar definitively planned for the Mk.2 ?

    1.Is the Radar operational? Have
    they fired R73 recently in Goa
    using Radar?
    2. Has the flight control s/w been
    tweaked fully? Dr.Shyam chetty
    said 3/4th of the FCS is
    completed. when will the full
    flight envelope will be
    completed before FOC?
    3. High AOA test is pending. its
    been told lsp-6 will be used
    for that…please elaborate.
    4. please get the inside story
    about the reliability ,
    maneuverability and other
    performance aspects from IAF
    pilots, if not confidential.

    Please ask them about the RCS of Tejas in comparison to other fighters like f-16,18 and Su-30 mki. There is little-to-no data available on it and what's available is pretty murky.

    Also, Give them our thanks and love for all the hard work they have put in for defending our home.

    In two day time LCA or Tejas get indeucted into the Indian Air force… three cheer to the Maker of this marvelous air craft…But yet I am little apprehensive. What ever the Indian do the Chinese seem to be five to ten year ahead, We need to closed this gap as soon as we could. For example The Chinese J-10 is in service for 6 year now and our only after like 10 year after it first flew. Now the Chinese has a J-20 suppose to be a fifth generation aircraft and our still in drawing broad, They have develop the ARJ21 regional aircraft and our RTA-70 again still in drawing broad. They have send a Man into space and we still figuring out how to… We need to Catch up and I surely think we Can"

    Mr Aroor, please inquire about the trials of BVR AAMs on the Tejas. What types are being considered – Derby, R-77, Mica – and when will firing take place ?

    Also, there are a wide variety of stand-off PGMs in IAF service – the KH-31, Kh-29 etc – will these also be integrated ?

    Its Great to see that the Tejas has clocked more than 1500 sorties without any incident or an accident. we indeed have come a long way in proving our ability to bank on indigenous technology & production quality.That should be the answers to all the critics.

    I wanted to know that can in-flight refueling be added on the current version as a future upgrade?

    Here`s my ques. –
    "Sir, we all are clearly aware of the LCA`s capability but still I would like to know from them that where does this Tejas stands in the competition with other fighters of its class around the world?

    Yes, of course its better than our neighbor`s JF-17 but I`m talking about other US, European and Russian fighters which have an excellent flight record(could it be compared to Rafael, Eurofighter, F-18, F-16 or the Mig-29`s). Could our LCA gain such respect as these fighter posses?

    [I already know the answer but i`m eager to know their opinion on this question]

    Hi! Thanks for providing this oppurtunity to ease off my pressure!

    1. Why was the Tejas decided to be a delta-winged platform?

    2. What is the solution that the Tejas team has come up with(Or still working on), to increase the turn rate and the alpha in the aircrafts prior to the mk2?

    3. Shiv, finally please ask the team to fly the tejas with smoke on in the upcoming Aero-India so that we would all get a glimpse of the AOA attained by the bird.

    Hey Shiv,

    Have a great time when you are with the Tejas team.

    Can you please find out if LCA Mark 2 will have canards? will it take the Gripen route? Coz, to the limited knowledge that i have, it seems to me that the delta configuration has poor Hi-AoA performance.

    Also, if there is an increase in overall size by 15~20%, are they inducting any stealth features to lower RCS?

    Thanks Shiv – Looking forward to your post on that day

    Hope you read this before leaving.

    1. How is the radar testing on the LCA going? This is India's first airborne radar. How is it's performance so far.

    2. Would there be a structural changes in MK2? Wing change/ size of aircraft/ increased weapon load/ increase fuel load?

    3. Has datalink on LCA been incorporated/ tested?

    4. Will EW be internal in MK2?

    5. Are there weight reduction plans for MK2?

    6. How is the maintaince experience of composites?

    Finally .. Will IAF release a photo of fully loaded LCA with weapons on all it's hard point?

    Sriram the ADA has already done its homework. The LCA was indeed tested with canards in wind-tunnel tests, and it was not found to give any substantial improvement in performance. So ADA decided to drop the canards.

    LCA's massive wing area (much larger than Gripen) gives it a greater instantaneous turn rate than Gripen, and a good FBW will give it a very decent sustained rate too.

    1) Titanium and Composites both are planned for use in the FGFA, with Tejas can they use Ti where they don't want to use composites?

    2) With Tejas designed even for high altitude operations, is Leh or any of those new bases in Himalayas being considered for deployment?

    3) When can we expect to see the Small Diameter Bomb in service with the Tejas?

    4) Is landing on remote airfields or highways ala Gripen being considered? including hot refueling?

    5) Any near future plans (before FOC) for airshows and exercises replacing Mig-21 & Mig27s in the later?

    6) Are computer simulations for the LSP-6 increasing AoA done? Setting aside the 3/4th flight envelop covered what percent does LSP-6 cover in the remaining 1/4th?

    Hey, Shiv Aroor,I bet you are a Malayalee (because you are smart). Any way, what matters is that you write good. Maybe once in a while you falter, and this is one! What is the fanfare about this nonsense Tejas. At this juncture when things are so complicated(technologically) what is the big hullabaloo when a wheel has been reinvented! Wake up man, be serious, this game has been going on for some time, I wonder why you have fallen into this trap. We who are smart know that this Tejas is nothing but a kit that has been assembled. Everything in it is 'phoren'. Our valuable resources have gone into this black hole and this will never end till people like you write! Crores and crores of Rupees gone into this 'mother of all dupes'. This HAL, DRDO, NAL, etc; are robbing you and me and our children and you don't care, or maybe you are just naive. We need to let the TATAS, MAHINDRAS, RELIANCES etc; to make great warplanes. And the Government to serve the people not to make warplanes. Shiv I hope you got the point. The last 50 or more years the Government destroyed the nation and they will never let India rise, by hampering or reigning in free enterprise. They are so corrupt and selfish, I wonder why you, are happy?

    @anonymous.Since you are anonymous I cannot address you in the first instance. Well, as of me I do work outside NASA in a mall and I am from INDIA. I would rather be robbed or looted by any company(pvt of course) than these Socialists the Baboos. I presume that you are not of Indian origin and hence unaware of things Indian. Let me be clear, this Tejas is just a hogwash, this is just a way of making a living(luxurious) for the people at DRDO, HAL, NAL etc; and we know it. As long as the Government is involved in making planes the public is being robbed, it is taxpayers money. It needs to go to the people of India not to the Baboos and their Swiss accounts. I don't have to mention the Bofors the army flats scandal the HDW scams etc; etc; The Government should not be involved in MAKING planes but rather let the Private Industry do it. India cannot afford this, no, no more! there are millions of mouths to feed children to be educated mothers and sisters to be supported. You are naive to believe that Tejas is the way, in the times of BVR missiles and High altitude loitering UCAVs and Space based precision kill weapons. Let good sense prevail, and let the youth of India decide what they need for their future instead of us destroying that, with our past…Jai Hind!

    Shiv, why do you call for such comments when you know that you will never answer them? About six months back, you asked for similar questions that you promised you will blog about. None of the questions raised by the contributors were answered.

    The least you could have done last time was to explain why you couldn't answer any of the questions your readers had asked. Even just a short line saying you didn't have time to ask those questions would have been sufficient. Instead, you just ignored everyone. Now, you are doing the same thing again. You are not alone in this though. Ajai Shukla similarly asked for questions he would ask ADA/HAL/DRDO folks in Bangalore, and when people bombarded him with questions, he too forgot to blog about it.

    Maybe there is too much food and booze and idle gossip at these events that real issues don't come up, eh?
