Payload may further reduce due to carrier operation due to short runway. Even if it carries 4.0 tons, It should be good enough. That is equal to payload of Mig 29.

Somebody get that Admiral an Naval LCA...!
If you read the whole post you'll see that I said exactly that.

According to ADA some 18 ski-jump take-offs have been done by the LCA-Navy demonstrators at the Shore Based Test Facility in Goa till date. Two of them at night. LCA-Navy is apparently ready to perform take-off tests from the INS Vikramaditya.
More than 200 approach touchdowns have been done at the SBTF. Including 18 high sink-rate touchdowns.

ADA says NP-1 & NP-2 LCA-Navy demonstrators are heading towards carrier trials from a ski-jump (STOBAR) carrier, which in our case is the INS Vikramaditya. They are however currently not capable of operations from a CATOBAR carrier.
well now ADA must start work for "CATOBAR capable" .

For STOBAR to CATOBAR transition, ADA only needs to fit NLCA with a stronger Nose-Wheel gear bolted with Launch-Bar (for CATAPULT SHUTTLE engagement) and certify it for loads up to 4 g acceleration at various Launch weights. Job done!
Other than Nose Wheel modification, Arrested landing certification - a common between CATOBAR and STOBAR- already takes care of 4 g stress load certification of the airframe.
A second option (however outdated) is using Bridle-Shutte-Cable mechanism just like French used for Super Etendards. It may not require any changes at all in present NLCA for CATOBAR compatibility.

Yesterday was 18th anniversary of 1st Flight of LCA (Tejas)
First Flight of NLCA from Vikramditya's deck would have been best gift to LCA and it's fan....
Hope it will come soon.

There is no plan to fly NLCA-MK1from an aircraft carrier. The tests are only to validate technology ans not the plane itself. So, a longer runway is used in offshore test facility than what would be available on a carrier. The idea is to make Tejas take off from longer runways and to validate all other technology other than short take off. Short take off requires Tejas to have higher engine power which can come only with NLCA-MK2

NLCA Mk1 may be under powered for a full load take off from carrier ( 4 Ton of payload) it's definitely not under powered for a clean take off attempt. A 10 ton takeoff weight with 100Kn engine & a 8 Ton takeoff weight with 80 Kn engine is same thrust to weight rati
ff course even this will be to validate technology.As far as runway length is concerned, carriers launch aircraft while on full speed against the wind...
25-30 knots speed against wind of avg speed of 5-8 knots gives the planes a air speed of 30+ knots even before they start.
Wonder how many tests could be done from the carrier?
Tejas has to be loaded onto the carrier at dock, INS Vikramaditya will travel into the sea, Tejas takes off & lands on a 'land' strip.
Then Tejas has to wait for INS Vikramaditya to re-dock - which may take several months! It's unlikely that the carrier would re-dock until its patrol op is completed. Also, it's unlikely that Tejas will be shipped/flown to the carrier-at-sea by other means!
IMHO they should spend their precious time doing full 'arrested recovery' at the shore based facility before doing just a take-off from carrier . A take-off op which will create a lot of media buzz but won't really add much to the program - but DRDO may be going just for that:MEDIA BUZZ
Pics of Tejas taking off from a carrier will convince 90% of the population that it is fully ready for carrier ops!
(just like Helina slung under a Rustom-1 for 'taxiing only' has convinced fanboys that Rustom-1 is an armed drone)
No where it is mentioned as just a Take-Off trial or landing trial. It means this trials include both. So either way it could be done during the active patrolling of Vikramaditya IMO.
You mean the 'arrested recovery' is fully tested on land (and Tejas is ready for carrier LANDING)?? When did this happen?
From Saurav Jha's tweet above: "LCA-Navy is apparently ready to perform take-off tests from the INS Vikramaditya"
NLCA already undertook multiple arrested recovery tests and simulated landings at INS Hansa.
Saurav Jha mentioned it as
He is simply talking about carrier trials. Not specifically of Take-Off trials.
Dude! Why do you keep arguing just for the sake of argument?
S.Jha's own tweet (that I already quoted for you; and is also available on this thread itself) states clearly that it's for "take-off" tests!
Oh.. I might have missed the tweet. Could you please show me that one?
BTW I am talking on basis of this tweet.
..................................................
Okkk. Then you might have missed some more tweets from the same source.
So now you see why I said that NLCA has already undergone landing tests. So how could you be so sure that its only Take-Off tests and not landings?
S.Jha in one tweet mentioned it as take-off tests and in another tweet on same day tweeted as just carrier tests.
So you are free to keep on your thinking on just a take-off tests and for time being I would keep my thinking on both the tests. Only time will tell what took place or even took place or not.
It's simple 'reading comprehension'!!
S.Jha explicitly states that it's take-off tests.
Only 18 sink-rate and bolter touchdowns on the shore based facility. None with ARRESTED RECOVERY!!
Without 'arrested recovery' how will Tejas land on the carrier? It can't keep doing bolters on the carrier until it runs out of fuel and crash! it'll look like an annoying bee hitting against a glass pane repeatedly until it drops dead!!
Many fanboys are precisely like you - weak in 'reading comprehension'. As such make up whatever nonsense comes to their minds; and worse argue relentlessly based on that!
