Guys Here are some of

• Status of PV-5 please ?.Tarmak007It is already undergoing ground tests after modifications and should start flying very shortly.

What's this pv 5 ? Is it lsp 6 ?
Spin tests and higher AOA is going to be tested in LSP 6 , means LSP 6 should be rolled out soon?

Ok got it trainer version... Some issues ?

PV5 is older airframe which is now integrated with EW suite. LSP 6 is not yet rolled out and will be for AOA tests

If the M2K is getting Spice 250 (as the DRDO Cheif said) then surely the LCA will be too at some point?

He mentioned SPICE 2000, which was pitted in a competition against the AASM 1000 (both 1000Kg class PGMs), not the SPICE 250 and if the 250 would be procured, it would be with the quadlauncher for the centerline station.

Nice!

@sancho it seems PSG was right (a rarity), the TP stated multiple times the LCA will have multiple ejector racks. And they seem to have sorted out the drag issues as he is saying they will be pushing the bird to 1.8 mach.

Not at all, he claimed about Rafales triple pylons in it's initial article (that btw was edited later ), that would gave LCA the capability to carry 6 x LGBs, while the test pilot said, that twin pylons would be added. Also PSG claimed about Israeli light weight LGBs in the MK81 class, while the twin launcher hints to the MK82 class, similar to what Mirage 2000 or Rafale usually carries.
Lets see, they made some drag improvements for sure, but so far it didn't paid out, maybe more changes are to come.

N-LCA looks better than MK-1....hope the development works won't be effected by delays. N-LCA would definitely be a potent fighter and would boost the Naval aviation unit.

So by looks you conclude that it will be a potent fighter? Btw, the current N-LCA is the same MK1 standard as the air force versions, the only differences are the navalisations, but the engines, the main part of the airframe and most systems are the same.

Don't you think the cockpit of the N-LCA gives a better 360 degree view and above all doesn't it look aerodynamically superior than the LCA-MK1.

How so? It is the same fighter, just that the cockpit is slightly angles for better view at carrier landings and the addition of LEVCONs, which again are mainly meant for carrier landings, although they might improve LCAs maneuverability too. However, the "looks" definitely doesn't make it better or even superior.

We will integrate tandom pylons to be able to carry more number of weapons. That is one of the FOC tasks.

Firstly, @sancho has explained everything that I wanted to say...and secondly and most important...being humble and gentle to people shows the true strength of a gentleman. There are two ways of explaining things @sancho choose the correct way and my dear you choose the wrong.

My Apologies, I beg to disagree with @sancho , Confrontal Tank are useless in LCA. LCA is basically a point defense fighter with other capabilities.

Remember one can not make omni platform weapon system. You look at EFT, it is Good A2A fighter with ground attack capabilities. Similarly Rafael is good ground attack fighter with A2A capabilities..

On same line LCA is A2A, Point defense fighter with A2G capabilities. MidAir refueling and Drop tank are two way to increase the range.

And unlike USA our Defense profile is not huge..

And unlike USA our Defense profile is not huge..

Which is wrong, otherwise IAF wouldn't insist on increased internal and external fuel capacity for the M2Ks and Mig 29s and keep in mind that both have or will have IFR capability too. In fact the last air chief made it clear, that IAFs aim is to have a fleet of fighters and AWACS or transport aircrafts, that can be refuelled in mid air. The problem is only, that you confuse it with extended range only or strike roles, but that's wrong. As I already said, the biggest advantage for LCA would be lower drag and RCS and especially as an interceptor, both are crucial! An LCA in normal interception config would carry at least a single centerline fuel tank, standard CAP config is even 2 x bigger wing fuel tanks. An LCA with either increased internal fuel or CFTs however, won't need an external fuel tank in interception role anymore (benefits => lower drag and RCS) and even in CAP it would need only a single smaller centerline fuel tank, or with CFTs no fuel tank at all (benefits again => lower drag and RCS).
When you then add the benefits of loads in strike role, the advantage of longer endurance in air defence or recon roles and even simply the possibly better flight performance, that is an important upgrade for LCA.

Tejas to Begin High-altitude Trials in Leh.

The Final Operational Clearance (FOC) campaign of Light Combat Aircraft Tejas is set to gain momentum with the high altitude trials scheduled this week in Leh. Aeronautical Development Agency (ADA) Director P S Subramanyam told Express on Tuesday that during the Leh trials, the aircraft engine would be started at lower than -10 degree Celsius.

“We will also evaluate the aircraft performance at low temperature and high altitude. This time, we need to also test the performance of various sensors at the hilly terrain,” Subramanyam said.

Only one aircraft is participating in the current trials with ground support teams already being positioned at Nasik, Pathankot and Leh.

“These trails will not exceed more than a week. We have the next phase of weapon trials in Jamnagar, scheduled in March,” the ADA chief said.

He said the number of test flights of Tejas dipped in January owing to the preparatory phase for the FOC campaign.

“Various activities for the FOC have been initiated much before the Initial Operational Clearance event in December 2013. Most of the FOC parameters that we need to achieve have reached the halfway mark,” he said. Currently the aircraft from the Tejas flight-line are being upgraded to the FOC configuration to undertake flight trials.

Hindustan Aeronautics Ltd Chairman R K Tyagi said the production activities at the company’s Light Combat Aircraft (Production Group) unit are pacing ahead as per the plan. “The project progress is being monitored on a daily basis now. We have completed the wings of the first series production (SP-1) aircraft and it has come out with nil deviations,” Tyagi said.

The HAL is mandated to deliver SP-1 in the next three months.

In the FOC phase so far, the aircraft engine was switched on using a jet fuel starter three consecutive times (three times in a row), as mandated by the Indian Air Force. A rainproof test was done on the limited series production (LSP-7) aircraft.

Didn't they miss the coldest patch for this testing? December and first half of January are the coldest months in northern side of subcontinent where temperature may go way below -10.

A Question: Had India tested all contenders of MMRCA at the same temperature (-10) during their Leh tests?

Good Thought! Not sure about MMRCA. They would have test the plane as they got. IAF has very high opinion of Western products anyway.

Tejas will be subjected to all possible trials. IAF will not do any compromise. Neither does the Indian army. Hail Indian (Foreign Lover) Military!

Doubtful, since they came at different times of the evaluation. US fighters and Rafale were the first in sept - oct, followed by the Mig and EF, the Gripen were splitted into C/Ds and NG, with the latter arriving only somewhere in spring.
