What are the updates on the LCA programme?
The work on LCA Mk1 FOC activities pertaining to integration of weapons and air to air-refueling probe, expansion of envelope is under progress and the FOC is expected by December 2017.

Hindustan Aeronautics Limited (HAL) is working on ramping up the production capacity from eight to 16 aircraft per annum. With increased level of outsourcing and enhanced participation of Indian private industry, HAL will be able to speed up the deliveries to cater to the present and future requirements.

The IAF squadron with three aircraft is already operational at Bengaluru since July 2016. It is planned to complete the order for 40 LCA Mk1 by 2019-20.

LCA MK1A is an improved version that incorporates enhanced combat capabilities like AESA radar, Air-to-Air refueling, Self Protection Jammer (SPJ), BVR missile, etc in addition to providing better maintainability features. The process of identification of new systems and their global Original Equipment Manufacturers (OEMs) is under progress. The development of this version is likely to be completed by the end of 2018. The series production will follow thereafter. Moving over to production of Mk1A from Mk1 is expected to take place seamlessly.


How is the FGFA programme progressing? What are the new timelines in this programme?
The Preliminary Design phase of FGFA is complete. Negotiations for R&D contract between Indian and Russian side is concluded and the final report submitted to the Chairman, Cost Negotiation Committee (CNC) for further processing. The development timeline would be 84 months after the contract is signed.

That's a farce as no FOC standard Tejas are being ordered. Production will shift from Tejas IOC to Tejas MK1A later even earlier ones will also be upgraded to MK1A. So even if they announce for the heck of it, it doesn't have any meaning, as production will be for MK1A. So they have to test for MK1A and not FOC standard. EVen if they announce FOC it will be symbolic.

 

[Pandora]

Reporter is confused ,per latest reports by SEP 17 FOC will be attended while IAF ordered 20 IOC and 20 FOC standard tejas.

 

[tejas warrior]

Expect FOC when MK1A flies as now FOC means MK1A.

No.

FOC for Mk1 will be achieved this year and it's different from Mk1-A.

 

[Abhishek Shrivastava]

What are the enhancement in MK-1A
if we have IFR, Gun and Derby and Python Missile in MK1, Is it Only AESA and improved weight which makes MK1A different?

AESA radar, EW suite, improved maintenance time (between sorties) due to rearrangement of the LRUs within the airframe, reduced weight, new flight software, possibly more fuel carrying capacity (resulting in a slight increase in range)!
Remember that Tejas Mk1A will not physically resemble Mk1; it is supposedly based on LCA Navy Mk1 - so visually too it will look different (and perhaps be more aerodynamic) than Mk1 (the landing gear of LCA Navy will give way to lighter AirForce variant of the landing gear)

 

[lcafanboy]

No.

FOC for Mk1 will be achieved this year and it's different from Mk1-A.

That's only for records.

Will it go into production?
NO.

Which plane goes to Production?
LCA MK1A.

So FOC for which PLane is required?
LCA MK1A.

Now think on this and then tell what does FOC means? And then deduce the answer. NOW FOC means MK1A.

This really doesn't make sense.

There will indeed be 2 separate FOCs as Mk1 and MK1A are two different aircrafts. Mk1 is the original air force version, while Mk1A is based on LCA Navy (whose airframe, flight control software etc is different). Whatever the final role, there will still be Mk1 aircrafts in IAF, as they ARE being built - as such they need an FOC before being fully inducted into the service

No.

Mk1-A is being developed for IAF.

20 planes of Mk1 FOC Configuration are on Order.

FOC for MK1 is required and will be achieved.

MK1-A is upgrade on MK1-FOC configuration.

 

[Scrutator]

No.

Mk1-A is being developed for IAF.

Yes. But the physical aircraft that will be called Mk1A by the IAF is based on LCA Navy Mk1 (and not the Tejas Mk1 that is being currently built and FOC'd)

 

[Scrutator]

MK1-A is upgrade on MK1-FOC configuration.

Wrong. Mk1A is an upgrade to the LCA Navy Mk1.

 

[kunal1123]

NO two separate foc is required.MK1A- is upgrade over MK-1 FOC VERSION ADDING SOME STRUCTURE CHANGE WHICH ALREADY VALIDATE IN NLCA (NP1 AND NP2 has already have flown more than 100 hour ) with some internal rearrangement and weight reduction. only extensive flight testing is required in MK1A version whi may take 3-6 month by three prototype(first 3 plane for testing )

So if Tejas mark one get foc in June , foc for Tejas mark 1 A can come in June to Dec 2018 , and goes in serial production in 2019 - 2020 .

Well that depend on how fast they are going for it . if they are able to take mk1a first flight before mid of 2018 then i am quite sure for serial production to start in 2019 itself. as current rate 5+11+16 the total order of mk1 is 40 only . so they need to start the process for mk1a at-least by mid 2019 to have production without slowing the production line. and add to that if 3(well 2nd complete) production line started in 2018 complete order of 40 lca mk1 will definitely over by mid 2019....
let hope and yes for lca mk2 i required ioc/foc but i think that will be quite faster than mk1....

One cannot just make changes to the flight control surfaces (like take LEVCONs from one airframe and slap it on another airframe) and 'validate' it in few months. The flight control software will need to be rewritten and retested in that case!!!
The Mk1A is based on the 18th revision of Standard of Preparation (SOP18) for LCA Navy Mk1 airframe (including the flight control software) - this has been thoroughly tested and frozen!!!

who say the are going to slap it in another airframe . most of mk1a is already in foc and as per levcons they are testing in nlca mk1. there are two prototype is already flawing and there is more than 2 year left before mk1a first testing is to be done. they need to tweak flight control software. it is upgradation with same airframe they are not going to rewright fcs from start. that might happen with lca mk2,it might....

Again...they're not going to just slap the LEVCONs from LCA Navy Mk1 (no matter how well it is tested on this airframe) onto Tejas Mk1 airframe and expect all to be hunky dory with few months of testing!! Changes in the flight control surfaces takes an exorbitant amount of testing......otherwise they could have gone directly to Mk2(if it entailed just a minor software upgrade for enlarged wings!!)

 

[Screambowl]

Is there any one liivng close to Hal airport in Bangalore who can take pics ?

No pics please

But LEVCONS are already being tested on the same airframe, though flight software might be different....

LCA MK1A and NLCA both look similar from outside....

If we're to get LEVCONS on LCA MK1A, how long does the testing and refinement take and how much advantage is gained by having them

Please explain in layman terms,

 

[Scrutator]

I haven't seen any official pictures/sketches of LCA MK1A. Please share if you have them.

But yes, I do expect LCA MK1A and NLCA Mk1 to look alike.

NLCA Mk1 has extended LEVCONs to help attain higher AoA and better low speed handling - besides a drooped nose and higher canopy (which I feel will reduce overall drag).
