According to Tejas FB page Admin. This sortie was to test Tejas landing abilities with heavy loads.

For some, it may not sound significant. But when MRCA-1 had started F/A-18 had been pitched as an aircraft with best bring back capability. Which means landing with the entire combat load in case none was used during a combat sortie.

Sorry bro, I don't agree.

With smaller fleet, higher availability is in fact difficult.

Aircraft in production is not a reason as SU30mkI availability is on lower side even if it's in production.

No, SU30MKI is not a good example. At the time this plane was designed, there were too many Russian latest technologies/materials integrated. Lot of these didn't even apply to Russian own service fleet. Latest technologies generally mean immature with lot weaknesses: low production rate, low endurance, hard for maintenance, etc. Russian vendors were still trying to fix problems of these new products. That is why SU30MKI got so low availability comparing to others' SU30 fleet.

On the other hand, LCA is built with mature tech from composite material to sub-systems, so the serviceability should be better at the beginning.

Wiating for the day when we see MERs on the inner wing pylons but damn this is a fine sight!

Should be noted that to this day JF-17 Blunder hasn't even got a dedicated pylon, their LDP has to be carried on the belly hardpoint! LCA has had this since day one.

I am good with 80% availability, or worse case scenario even at 70% too.

75% is the IAF's target for their entire fighter fleet; assured for Rafale (PBL), they are trying hard to get MKI to this level (was 50% in 2014, around 68-70% today) likely they will sign a PBL with HAL for LCA also.

It's going to be MUCH cheaper to keep LCA and Rafale at 75% than the MKI though, the MKI burns through spares at a disgusting rate and because it doesn't have full on board diagnostics like LCA and Rafale a lot of preventitive parts changes go on.

It's also much easier to work on LCA and Rafale, Russian equipment is known for being a pain to maintain, an AL-31P engine for instance takes the best part of 12-16 hours to take out and replace on a MKI, the same job can be done on the Rafale's M88 within a couple of hours.

One of the the most overlooked parts of the Rafale is that it will bring about a revolution in how the IAF works on its fighters, instead of needing a BRD, all major work can be done at the SQN base itself, it doesn't need to fly out to a specialist depot at any point in its life Hope LCA can benefit from these lessons and I'm particuarly excited to see the Safranised Kaveri, one of the best parts about M88 is that it is modular.

Russians have been screwing India for too long.

 

[mayfair]

The problem is that with MKI as far as I understand, it has been largely done by throwing money at the problem- no augmenting the local supply chain, but piling up the spares and reserves from the OEM.

We cannot afford such a situation with Tejas or Rafale.

They have already qualified 2x 1000 pounders on MER in tandem configuration on inner-board pylons. Tune to 04:14 in the following video.

Just to add, unlike MER in side by side configuration, tandem configuration causes lesser wave drag. Also, frontal RCS is affected lesser in this configuration. The drawback, of course, is in length flexibility.

likely they will sign a PBL with HAL

So far IAF is reluctant to sign PBL with HAL for neither Su-30MKI nor HAWK 132s.

The irony is, IAF which criticises HAL for trade unions and its protectionist methodology is actually doing similar wrt its BRDs.

I am good with 80% availability, or worse case scenario even at 70% too.

For perspective, the French Rafale fleet has got 56.6% availability, the total US fleet has 53% & Russians have about 45-55 (though there are some stupid claims such as 93%). Thus the 68% for MKI looks a lot more impressive

Absolute availability depends on the cycling time. For example, a Su30 needs overhaul every 4 years which in turn takes 1 year. Hence by cycling Su30 at equal intervals to maintain employment consistency, we get availability of 75%. It can be made higher by hiring more people and getting all Su30 overhauled prematurely to get higher availability at any point of time. These availability is just a procedural figure and is not absolute. So, one must not break one's head speaking of availability during peace time operations.

Problem is we hav illiterate journos in India who wrote bs in news outlets without knowing anything.

That guy, whoever he was forgot to mention about our successful development of Helicopters. His suggestion that we should have manufactured Gripen instead of developing Tejas is nothing but :bs:. We have licence manufactured MiG21 and Gnants in past but unlike Tejas they failed to kick start our aerospace industry.

Mk1 not mk1a, and yes these specs are from moving ioc 2 to FOC, however, FOC variant will have aoa 28 degrees, 1.8mach and 8g loads.

Can someone please ask them the ferry range on internal fuel? Im pretty sure its 1700 kms, but I need a confirmation.

Also, as per the same thread, supersonic drop tanks are ready for integration onto aircraft.

450L it should have been, last year ada source had said design in final stage of supersonic drop tanks.

Almost all indian defence journalists r sellouts. There is a big lobby activated to curtail tejas progam .You can easily identify this lowlives from recent articles discouraging lca project

Actually, opinion on Tejas aside, Hush Kit is a very well maintained online portal on military aviation. Some true gems on past incidents and aircrafts can be found there. I don't agree with their op on the Tejas, but can you blame them, when our own air force pisses on the LCA?

Did IAF piss on LCA? The initial 20 LCA MK1 was ordered in 2006 and not 1 was delivered till 2014. This was MK1 with imported engine, radar, ejection seat and avionics. Can such a delay be explained by throwing the ball at IAF?
