Progress on LCA Mk.2 cockpit config
SOURCE: SP Guide Publications
The look and feel of the all-glass cockpit that the LCA Tejas Mk.2 will sport is fructifying with the Aeronautical Development Agency announcing that the main display will involve two 6×8 Smart MFDs and one 5×5 smart MFD in centre console “based on the latest and best design technologies currently available in the market”.
The ADA is looking for a full solution to its SMFD needs for the LCA Mk.2 programme. The capability exists in country, though a competitive process will now ensue. The ADA is looking for active matrix TFT color liquid crystal display SMFDs with separate LED backlight for day and night modes with redundancy for backlighting in both the modes, touch screen capability (will be the first Indian aircraft to sport touch screen panels), anti-reflection coating, full sun readability and night vision capability, compatibility as per NVIS Class B MIL-STD-3009B, EMI protectio, the bezel shall have push buttons, rocker switches and rotary knobs, auto brightness control (ABC) of the display using illumination sensors placed on bezel, capability for windowed image overlay driven by the display processors, dual channel video to support redundant display processors, continuous health monitoring with periodic built-in-test reporting along with its normal operation, provision for operator Initiated Built-In-Test, In-situ programming capability. Conduction Cooled with no external cooling for the entire range of operating temperature.

For LCA Tejas, it’s now about months, not decades - The Times of India
NEW DELHI: India's defence R&D establishment will have to fire on all cylinders to fast-track the meandering Tejas light combat aircraft, which is still not fully operational or combat ready, if it does not want the Narendra Modi government to critically re-examine the entire project.
The Tejas project, in fact, may even get some competition in the light-weight fighter category. Defence minister Manohar Parrikar said "some other single-engine, lighter fighter" other than the home-grown Tejas could also be considered for a "Make in India" project to replace the obsolete MiG-21s.
Restricting the acquisition of expensive twin-engine French Rafale fighters to just 36 for now, instead of the original plan for 126 MMRCA (medium multi-role combat aircraft), Parrikar stressed he was trying to plug operational gaps in airpower by improving serviceability of "heavy-weight" Sukhoi-30MKIs as well as "pushing" the DRDO-HAL combine to deliver Tejas faster.
"Don't compare Rafale, a top-end fighter, to MiG-21s, which we will phase out in about six to 10 years. The replacement for MiG-21s will be Tejas or some other single-engine, lighter aircraft. Tejas ki maar bhi kaafi hai (Tejas packs a punch) and it's much better than a MiG-21, but has certain limitations," said Parrikar.
Though some interpreted this to mean impending doom for the Tejas project, a top official dismissed it by clarifying the government was "just keeping all options open" to make "numbers" with IAF down to just 34 fighter squadrons when 44 are needed. "There could be scope for a single-engine fighter, which would be much cheaper than Rafale, somewhere between the capabilities of Rafale and Tejas," he said.
Incidentally, the original plan was that six squadrons each of MMRCA and Tejas would replace the existing 10 Mig-21 and four MiG-27 squadrons. Parrikar, on his part, said, "In the next four to five years, we can add about six LCA squadrons if we push HAL, which I am doing."
DRDO-HAL will certainly need to be pushed on the Tejas project since it's critical for self-reliance in defence production. The first Tejas was handed over to IAF on January 17 but it was in "initial operational configuration (IOC)", which signifies its airworthy but not combat-ready. The pilot training and maintenance manuals are also still not ready, delaying its actual induction into IAF.
The fighter's final operational clearance (FOC), with integration of all weapons like guns, laser-guided bombs and BVR (beyond visual range) missiles as well mid-air refuelling capability, is likely to be delayed beyond the re-revised deadline of December 2015.
The Tejas Mark-II version which the IAF actually wants — with more powerful engines, airframe changes, weight and drag reduction — will begin to come in only by 2021 or so. So, Parrikar will need to do a lot of pushing if he wants swifter deliveries of the multi-role fighters.

Naval LCA carries out ‘hot refuelling’
Anantha Krishnan M has tweeted last image of Naval LCA carrying out ‘Hot refuelling’ in HAL premises in Bengaluru . Meaning of ‘hot refuelling’ means Fueling With Engines Operating . Hot refueling is performed only when operations require rapid turnaround of aircraft, since hot refuel-ing is significantly more dangerous and costly interms of fuel and manpower expenditures. Only pres-sure hot refueling is performed.
A minimum of three ground crew personnel are required for each hot-refueling operation. ‘Hot refuelling’ becomes necessary in case of missing Aerial mid air refuellers in active combat patrol zone .

* Nowhere in the world does so much of the envelope have to be proven for FOC. IAF's policy with regard to this needs to be reviewed.
* To refine a combat jet. Everybody learns and the combat jet becomes better.
* Everybody tries to get their homegrown fighter into some sort of squadron service and series production first. Bcoz that is the real way.
* Our favorite R&D org is trying its best to complete hawa bahadur's changing requirements by end 2015.
* Our bird is yet to fire new laaang range A2A because of Yehudi non-delivery. Stocks from Naavik Sena will be used now.
* People at our favorite R&D organization are completely demoralized at the moment. They sounded quite dejected. Talked to them this morning.
* Any move to sideline Tejas with an imported design would be nothing short of the Weimar betrayal.
* Why does a radome need to be changed right at the end of a program? And how many jets have had to be IFR qualified before FOC ?
* I just hope the Tejas Mk-I does not end up going the BAC TSR.2 and CF-105 Avro Arrow way.
* We need some strong statements in support of the HAL Tejas. And the strongest statement would be an order for 4 more squadrons of Tejas MK-I
NOT good for tejas????
