LCA is being made to fire all BVRs, R-77, Astra, Derby and if possible, Aim-120 too.The choice of LCA BVRAAM has everything to do with it... n'est pas?
what about the datalinks/bus ? aren't they all different ? how will it work out ?LCA is being made to fire all BVRs, R-77, Astra, Derby and if possible, Aim-120 too.
That doesn't make any sense. It only needs one BVRAAM type. Having 3-4 different types that all do the same job is a logistics nightmare and I really doubt if IAF is going to be that redundant in wasting money.LCA is being made to fire all BVRs, R-77, Astra, Derby and if possible, Aim-120 too.
If it has a 1533 MIL databus, the software shouldn't be a problem except thousands of hours of reprogramming code dealing with launching to interface with the radar and HUD... even helmet sights. The hardware change requires new launchers for each station and rewiring them for it. Then testing actual launch, loadout configurations, weight and drag issues. Whole host of things to deal with.what about the datalinks/bus ? aren't they all different ? how will it work out ?

Even helmet sights. The hardware change requires new launchers for each station and rewiring them for it. Then testing actual launch, loadout configurations, weight and drag issues. Whole host of things to deal with.
all these systems are integrated on three 1553b buses by a centralised 32-bit mission computer (mc) with high throughput which performs weapon computations and flight management, and reconfiguration/redundancy management. Reversionary mission functions are provided by a control and coding unit (ccu). Most of these subsystems have been developed indigenously.
The digital fbw system of the lca is built around a quadruplex redundant architecture to give it a fail op-fail op-fail safe capability. It employs a powerful digital flight control computer (dfcc) comprising four computing channels, each powered by an independent power supply and all housed in a single line replaceable unit (lru). The system is designed to meet a probability of loss of control of better than 1x10-7 per flight hour. The dfcc channels are built around 32-bit microprocessors and use a safe subset of ada language for the implementation of software. The dfcc receives signals from quad rate, acceleration sensors, pilot control stick, rudder pedal, triplex air data system, dual air flow angle sensors, etc. The dfcc channels excite and control the elevon, rudder and leading edge slat hydraulic actuators. The computer interfaces with pilot display elements like multifunction displays through mil-std-1553b avionics bus and rs 422 serial link.

Multi-mode radar (mmr), the primary mission sensor of the lca in its air defence role, will be a key determinant of the operational effectiveness of the fighter. This is an x-band, pulse doppler radar with air-to-air, air-to-ground and air-to-sea modes. Its track-while-scan capability caters to radar functions under multiple target environment. The antenna is a light weight (< 5 kg), low profile slotted waveguide array with a multilayer feed network for broad band operation. The salient technical features are: Two plane monopulse signals, low side lobe levels and integrated iff, and guard and bite channels. The heart of mmr is the signal processor, which is built around vlsi-asics and i960 processors to meet the functional needs of mmr in different modes of its operation. Its role is to process the radar receiver output, detect and locate targets, create ground map, and provide contour map when selected. Post-detection processor resolves range and doppler ambiguities and forms plots for subsequent data processor. The special feature of signal processor is its real-time configurability to adapt to requirements depending on selected mode of operation.

All these options have been kept open. The LCA can integrate and fire any of the above missiles depending on availability during war.That doesn't make any sense. It only needs one BVRAAM type. Having 3-4 different types that all do the same job is a logistics nightmare and I really doubt if IAF is going to be that redundant in wasting money.
And what does ASR said?To follow ASR.
And others are children of lesser gods? Oh and this "pioneers of everything" has been gone too much far, please spare us.You are talking about GB and Germany here. They are the pioneers of everything. If they work on something they are not wasting tax payers money.
It is not "simply flying". It has demonstrated lot of capabilitiesLCA is supposed to fill ASR, not simply fly.
It is not a brief and closed chapter, it clearly shows how to stick with the platforms and make it mature not wait for eternity to induct. And it clearly debunks your so called theory that only "mature" platforms gets inducted.A brief and closed chapter. This was a problem. LCa's problems cannot be fixed without starting the Mk2.
Others are children of lesser gods? Keep your blind worship to your self.You are talking about GB and Germany here. They are the pioneers of everything. If they work on something they are not wasting tax payers money.
And they are getting F-35, at least GB is.
This is how every plane gets inducted, goes through IOC, and then FOC. No body has claimed that everything is done. This is the process the air craft follow. If the FIC is given with not fulfilling the ASR then talk.Fill ASR properly. Then we will talk. If LCA does not fit ASR, then it cannot be used for anything, including replacing Mig-21s.
Give answer to what question has been asked, pleaseASR.
How the bird was "accomplished" by investing on it right? And still there are periodic developments going on in that that is how it is done. How it will remain the same even after FOC? It will add the weapon mix that is needed. IAF pilots have to get used to these planes in large numbers so larger the number, it is better. Moreover larger number gives the idea about spare managment, this is our plane, we can not bring foreign expertise especially regarding this plane.You are comparing accomplished birds to LCA. There is nothing to twist.
Notice that IAF had inducted only 1 squadron of Su-30k and then replaced it in 4 years with the MKI. But LCA Mk1 will remain the same even after FOC. LCA will still not clear ASR. A second squadron was not required.
That is why it has been granted IOC, not FOC. This is how is done across the globe.But LCA still does not fit ASR.
The funding for TD 1 was given in 1993. So The CLAW team was building the software in US, and we know the story of source code denial which made the LCA delay it's flight, nothing new here.You are talking about DELAY with LCA? Hahahahaha!
LCa was supposed to fly in 1990. Then it was supposed to fly in 1996. But it only flew in 2001. So, are you still talking about delay?
So now IAF for eternity will stick to 6 tankers only? Don't bring unnecessary arguments. In flight refueling is given to the plane which needs it. If some plane's mission is over it can be landed in the base, refueled and flown again.As usual you twist everything you say by yourself. The tankers are never available 24/7. Only 6 tankers for 1000 fighters, get the point. Even MKIs will never have access to tankers contantly. At least MKIs will manage without tankers, but LCA cannot unless the Mk2 has major design changes.
Has it been granted FOC?And it still does not full fill ASR.
Well, the result was not in your favor.They did interfere. US definitely did and so did USSR.
Luckily, the war was for tiny period, if it extended then?It was for a very tiny period. France never stopped us modifying the aircraft because the aircraft was eventually modified. Stopping spares supplies for 4 weeks isn't a big deal.
What? So in the world there was only two countries who were capable of producing extra wheat? And with those two friends we have been kept out from nuclear trade for 3 decades.Had it not been for USSR and France, we would have been eating Grass now.
Because, there was no experience in building simulators, and no experimental plane to test it. The CLAW was tested on F 16 XL first to see it's handling capabilities.Then why did LCA team go to US for help if the fighter was supposed to be indigenous?
So you except, that there is connection between military and economic power? You can have only one, otherwise you are a dead duckJapan is a dead duck. It has no real growth or pull in international circles. Imagine a country like Russia and it still bends backwards whenever US intervenes. Poland is getting its ABM shield and Europe cannot be held hostage by Russia through Gas. All because of US.
The question is IF, so till then spare the thoughts.If the Chinese work out a way to stop MKI and MRCA, it will automatically mean LCA is taken care of. Duh!
HUGE? out of sanctioned strength of 39.5 squadrons, only 2 a mere 5%.A huge proportion of the IAF budget is going for an aircraft that is not going to fullfill ASR even after 2012. It's a waste of time to induct it. One squadron was ok like the Su-30k squadron before going for MKIs. But why 2 for the same purpose and for apparently no reason. IAF wants the Mk2 anyway. So, IOC and FOC for Mk2 will start all over again from 2014.
Ah now engine, there is a word called START, you need to start it, it is a journey.A foreign engine does not help indigenous efforts. If the US stops supplying spares, then the entire project will fail until Kaveri is ready. So, there is no real difference between LCA, MKI or MRCA wherever IAF is concerned.
Slowly Trying to get me do the dirty and difficult job eh ppgj? Thats the whole point. When there is nothing told about Tejas AOA how can we logically discuss it. Most of the posts here are assumptions. This will happen in future,this will fly by 2016, that will be ready by 2014. We just have the shell called Mark 1. And thats precisely why I say performance parameters should be revealed after LSP 6. This aircraft is supposed to define the AoA capabilities of Mark 1. Lets see how much info is shared. Lets all wait and see.i am also talking of LCA as it is now!!
validating is a precursor to induction via IOC (already happened) and validating more making it combat ready at FOC, a stage which should happen in 18 months to 2 yrs - a normal time for any fighter.
thrust on IAF?? IAF has a team at ASTE to oversee day to day LCA development. do you even know that?? have you heard of what the test pilots speak of LCA?? don't read quotes of the press in a way to suit your belief. LCA mark 1 though a little underpowered can replace many platforms in IAF post FOC.
my optimism stems from the fact that the LCA as of now has far outgrown from it's original plan. this is India's baseline to build on... you need to think of "balance" wrt now and the future. the ACM himself took back his words but you are not!!! while you stick to his one-off comment at IOC function you you don't stick to his clarification later. there it is - "balance".
are you part of ADA?? what do you know that others don't know about LCA AOA?? why don't share?? why not discuss it threadbare and conclude?? simply saying ADA hides and sundry does not help. since you talk about being a tax payer why don't file RTI or even write to MOD and clear your doubts??
You are grabbing at strings as usual.And what does ASR said?

Ah now engine, there is a word called START, you need to start it, it is a journey.
Where were you hiding all these days? Thanks fulcrum. Lets lever out everyone mateThis whole LCA saga is a typical example of piss poor Project Management.
I wish this LCA didn't exist and it was all a bad dream. But unfortunately it isn't. If only we had taken up the offer when the Russians offered to sell the sovereignty(yeah not just license they offered the Mig-21 completely for 800k or so!) of the Mig-21 back in the late 80s- early 90s, we wouldn't be in this mess, with falling force levels.
And I'd like to add that Mig-21 is the second best interceptor in our Airforce, the first one being the Mig-29. Yeah, MKI is bit slow to be an good interceptor. Anyone with little knowledge of India will knows that this is a big country and interceptors are the most important of all fighters to keep our airspace safe. Yet, this LCA, which is being touted as Mig-21 replacement, can't even reach speeds of MKI. The ACM knows this pretty well and the other handicaps of LCA(poor TWR, costly, dubious G tolerance etc etc) hence his displeasure with the LCA. During the 80s, the poor bastards in the IAF thought LCA would be like a mirage with it's delta wing(Yeah, French named their fighter Mirage due to its speed), but they had no idea of the incompetence of the ADA/HAL. Hiding behind the poor excuse that it is a state owned entity doesn't cut it! China's, heck even Russia's R & D industry is state owned. And we all know Russia's industry is anything but incompetent.
Ah, so you don't have answered to the questions asked so running away.You are grabbing at strings as usual.
So, isn't that a known fact? I don't think any body is trying to hide it. ADA director has confirmed that due to mid way changes in ASR some of the parameters will not be met without new engine. hence the MK 2 project has sanctioned. It does not means that a plane is completely useless that you are trying to portray.I will repeat it again. Even after FOC LCA Mk1 will Not fill ASR.
are you blind or what?? just go back and check the posts about IOC and FOC AOAs for LCA mark 1 which have been posted.When there is nothing told about Tejas AOA how can we logically discuss it.
only if you knew how design & development work, you would not be asking this. your hate for LCA is clouding your judgement.Most of the posts here are assumptions. This will happen in future,this will fly by 2016, that will be ready by 2014.
shell is hard to break.We just have the shell called Mark 1.
on the one hand you say "Lets all wait and see" and on the other you running all over whining that ADA does not know what is AOA/hiding it and what not??And thats precisely why I say performance parameters should be revealed after LSP 6. This aircraft is supposed to define the AoA capabilities of Mark 1. Lets see how much info is shared. Lets all wait and see.
No. The questions are too dumb to be answered. You are just running around in circles. None of your posts have anything that allows you to think. It's like an interview and you are asking questions that make no sense. The interviewee just walked out. That's all.Ah, so you don't have answered to the questions asked so running away.
That's wrong. The LCA Mk1 does not even fullfill the old ASR. The LCA cannot handle sustained turn rates at the required payloads at all. It has a lot to do with the underpowered engine.So, isn't that a known fact? I don't think any body is trying to hide it. ADA director has confirmed that due to mid way changes in ASR some of the parameters will not be met without new engine. hence the MK 2 project has sanctioned. It does not means that a plane is completely useless that you are trying to portray.
Oh yeah, when some one counters your baseless claims and asks it to prove, it becomes dumb. So are you claiming here as an absolute and some body who can not be questioned?No. The questions are too dumb to be answered. You are just running around in circles. None of your posts have anything that allows you to think. It's like an interview and you are asking questions that make no sense. The interviewee just walked out. That's all.
So what? The corrective measures have been started, if that is not done then it is a different matter.That's wrong. The LCA Mk1 does not even fullfill the old ASR. The LCA cannot handle sustained turn rates at the required payloads at all. It has a lot to do with the underpowered engine.
You have been given with the links, about different planes (EF and f 16 which according to you is gold standard as they are sons of greater gods), and you are still sticking to this baseless claim.You are talking about inducting a sub standard product and saying it is done the same way all over the world. Nobody does that. They induct yet to be finished potential state of the art products and wait till its ready.
oh yeah, another claim of absoluteness, get over it.Also you know nothing about international politics. You are just grabbing onto strings and believe the whole world is out to get us.
That is why it is granted IOC? Or it has been granted FOC?I have the highest ranking officials in the Air force and Navy backed by simple logic which says the LCA Mk1 is a prototype bird that needs a LOOOOOOOOT of work that is yet to be done.
Things are happening step by step, it's a good step by IAF to START the induction, so that other processes like training of technicians and familiarity with bird, checking out spare management can be kick started. Every plain goes though this process nothing new. And regarding the fighter induction, there has been no reduction in funding for either upgrade of existing fleet, or to buy new fighters. So claiming that LCA induction is stopping all that is baseless.The fact that IAF will help ADA test the fighter for 2 years and then immediately start testing the Mk2 for 2 more years is testament to the fact that IAF is in need of fighters ASAP. But, they want good fighters, not low quality ones. IAF wants ADA to succeed. But it's not happening. The very fact that IAF has accepted LCA Mk1 itself suggests they want ADA to succeed.
You forget the simple thing that when Gripen got inducted in what ever form it was given and then other models where planned with the real world experience. And now they are using there funds to develop something, why should we worry about it. It's there money they can use it the way they want.Take a look at Gripen. Swedish Airforce is not planning to buy the Gripen NG. But Gripen NG development is being carried out by SAAB independently without help from their air force. And the fact that IAF requirements for Gripen far surpass what they want even in LCA Mk2 shows that Saab is capable of turning their prototype into a real fighter even without help from their air force. If they lose the MRCA deal, no Swedish citizen will tear his hair for it.
LCA was and is getting developed to meet IAF requirement, so user involvement is necessary. And there is no standard like one squadron has to be inducted for IOC.If Saab can develop Gripen NG without user involvement then ADA can at least try to finish LCA Mk1 without user involvement. Even 1 squadron was enough.
LOL. Like what?So what? The corrective measures have been started, if that is not done then it is a different matter.
*Roll eyes*You have been given with the links, about different planes (EF and f 16 which according to you is gold standard as they are sons of greater gods), and you are still sticking to this baseless claim.
We survived absolute economic sanctions and you are more worried about spares. Haha.oh yeah, another claim of absoluteness, get over it.
ASR? So, ASR can go to hell. Nobody cares if it is useful or not as long as it looks pretty. Wow.That is why it is granted IOC? Or it has been granted FOC?
"Every planes goes through this process." NO. Every plane that is going to achieve ASR will go through this process. LCA Mk1 will not achieve ASR goals. That has already been made clear.Things are happening step by step, it's a good step by IAF to START the induction, so that other processes like training of technicians and familiarity with bird, checking out spare management can be kick started. Every plain goes though this process nothing new. And regarding the fighter induction, there has been no reduction in funding for either upgrade of existing fleet, or to buy new fighters. So claiming that LCA induction is stopping all that is baseless.
Gripen surpassed ASR. It is a success.You forget the simple thing that when Gripen got inducted in what ever form it was given and then other models where planned with the real world experience. And now they are using there funds to develop something, why should we worry about it. It's there money they can use it the way they want.
LCA Mk2 is being developed to meet requirements. LCA Mk1 cannot meet requirements and simple logic dictates that.LCA was and is getting developed to meet IAF requirement, so user involvement is necessary. And there is no standard like one squadron has to be inducted for IOC.
Honestly , dude your such an absolutist.LOL. Like what?
*Roll eyes*
We survived absolute economic sanctions and you are more worried about spares. Haha.
You don't realize that we could have still been achieving only 3% growth in 2010 had it not been for the vendor countries. China would have taken AP and Aksai Chin long time ago.
ASR? So, ASR can go to hell. Nobody cares if it is useful or not as long as it looks pretty. Wow.
"Every planes goes through this process." NO. Every plane that is going to achieve ASR will go through this process. LCA Mk1 will not achieve ASR goals. That has already been made clear.
Gripen surpassed ASR. It is a success.
LCA Mk2 is being developed to meet requirements. LCA Mk1 cannot meet requirements and simple logic dictates that.
Forget the new even the old ASR is not being met. LCA Mk1, after FOC, will still not generate the sustained turn rate required nor is it able to carry the required 4tons external payload at the required range. The undercarriage is still overweight by 500Kg.
Even 1 squadron is too much.
