It took almost 3 years and record breaking test flights of 450 for Drdo along with HAL to achieve IOC-2 for Lca Tejas Aircraft; Tejas which achieved Partial IOC-1 in January 10, 2011, will be granted IOC-2 on 20th December of this month, which will also lead to formal induction of Tejas into Indian air force after almost 13 years in testing after its first flight in 2001.
IOC-2 clearance also gives Tejas operational capability to use WVR (Within Visual Range) AAM (Air to Air Missile) like Russian made R-73 in Active combat roles and recent test conducted in Ins Hansa base in Goa over Arabian sea confirms that Tejas now has ability to track and destroy aircrafts Within Visual Range .
IOC-2 also clears Tejas to be used for Ground attack roles and have cleared tests for use of laser-guided 1000-lbs bombs and unguided bombs. DRDO plans to achieve FOC by end of 2014 , FOC certification will include integration and Successful firing of Rafael Derby or the Vympel R-77 for BVR ( Beyond Visual Range ) AAM (Air to Air Missile) Roles and also will require clearance of High Altitude Bombing runs which will be carried out in Leh next .
FOC will also see Demonstration of Inflight Air-to-Air refueling capability by Tejas aircraft , Fixed Refueling probes in past have been successfully integrated and tested on ground and current LSP ( limited Serial Production) Tejas Aircrafts already have required Piping and plumbing systems integrated in the aircraft so adding Refueling Probes will see lesser time consumption .
FOC will also require higher AOA (Angle of Attack) from current 22-24 degrees to 28 degrees but this also has high risk element of Flame out. usually aircrafts are designed to handle much higher AOA then 28 degrees but Tejas Air-intakes which are smaller and have some design flaws might make it High Risk Test for Tejas , But ADA and HAL are planning to integrate a Backup Power Pack to allow engine restart if flames out does occur has a safety mechanism.
HAL has promised to deliver first SP (Serial Production) 1 and 2 by end of March 2014 and another 2 aircrafts by end of 2014, IAF has placed orders for 20 IOC-2 Certified aircrafts and 20 FOC certified aircrafts based on Tejas MK-1. HAL Plans to start work on first Prototype of Tejas MK-2 next year and have it ready for its first flight by end of 2015, GE will be sending first batch of F414-GE-INS6 which will power Tejas MK-2 in early 2014.
Tejas MK-2 will also have a newly laid out cockpit layout with better computing power since it also be housing new mission control computer, Samtel Display Systems(SDS) is also working on touch based Multi-Function Displays (MFD) for Tejas Mk-2 , which will later find its way in AMCA too .
Tejas Mk-2 will also see structural changes in the aircraft which will be noticeable in wider wing span to carry extra weapons load along with extra fuel, aircraft will also have large air intakes to let the high thrust engine generate additional power for the aircraft, engine change for Tejas Mk-2 will result in the rear fuselage being changed too.
Commonality between Tejas Mk-1 and Tejas MK-2 will be digital Fly by Wire (FBW) Flight Control System (FCS) along with some avionics which both aircraft will share, but sources also told us that FBW Software will require some modification in them to support structural changes which Tejas MK-2 will have.
