Someone please tell me difference between MK1 and MK2, I'm confused
Since MK1 will also be using GE F414 engine why everywhere its mentioned air frame of MK2 is increased to occupy F414 engine?
MK1 is also using F414 engine so why its air frame length not increased? and what are other notable differ

MK-1 is using GE404 NOT GE414
MK-2 is in Prototype building stage ( Hoping ). So not much reliable information as of now.

MK-1 is having lower trust to weight ratio that's why MK-2 will have more powerful engine.
And hopefully other drag related issues will be solved.

MK-2 is supposed to come with AESA radar and may be more powerful avionics.

More correctly we have to wait till the first flight of the prototype in next few years to tell the diffrence. Right now different engine is only sure things we know

Actually mk1 is not using f414. its using f404. that's the main difference between those two. and there is no increase in airframe in mk1 but mk2 wingspan slightly increased and its airintake and frontal nose also increased. and other difference are.,
mk1 payload 4tonne and mk2 will be 5+tonnes. mk1 uses MMR and mk2 will use AESA. internal fuel capacity will be increased. hardpoints may be 9 from current8. and others include high tech digital cockpits,mission computers,IRST,EW suitesetc., you can see all these changes in mk2.

When MK2 prototype will be ready?

MK2 prototype will be built during 13-14,I'm not sure about 1st flight though.

1st flight will commence in 2015/2016 and induction around 2018,Same time as Rafeal's induction.

From http://www.hal-india.com/tender/ardc/NIT_1430_18-06-13.zip

. HAL-ARDC is taking up for development and Qualification of certain LRUs required
for catering to LCA-Mark 2 version. The first Prototype aircraft is slated for built during
2013-14, while series production(s) are planned for Inducting to fleet which is stated to be
taken up in two phases commencing from 2016 onwards.

MK2 build began on december last year,so its quite probable that 1st flight will take place on 1st quarter of 2014.

I hope so buddy but slow bureaucracy will push it further

From above.
1)FOC will be given before December 2014.
2)HAL is targetting around 16 LCA's per year during its peak production rate.

Very interesting points:

When MK2 prototype will be ready?

in the end of 2014 or early 2015.

in the end of 2014 or early 2015.

Is the production of MK1 has begun?
when it will be inducted into IAF?

just now HAL has given its LSP8 to IAF. after extensive trials with LSP8, our IAF will give its nod to go for production series. most probably this year end you can see your production variant 1. first squadron will be inducted in 2015 with 20 mk1 aircraft.

LSP 8 is in the line for more than an year. So far I heard SP-1 is getting ready.

no production variant not yet started. actually at present HAL is repairing its LCA production unit by replacing 3rd generation aircraft tools with 4th generation aircraft production tools. so it will take another 1 to 2 months to re open a LCA production unit.
