They should opt for another batch of 83 LCA MK1A
The home-grown fighter is slated to be equipped with indigenous flight control computers, air data computers which would be supplied by BEL under this contract.

Tejas LCA test pilot Suneet Krishna (who flew thousand hours on Mirage2000) said "take offs are sharper in Tejas Mk1 than mirage2000
TejasMk1 has higher TWR & lower wing loading (leads to better STR & ITR) higher BVR Missile range
Tejas Mk1A gets Uttam AESA radar too
QWIP equipped IR missiles are very difficult to jam
Tejas Mk1 & Tejas Mk1A are slated to receive latest MICA missile of Mirage2000 as well
Tejas_LCA has 1/3rd of Mirage2000 RCS,making it difficult to track & locked.
Has a bigger radar to track f16 types
Plus Mk1 can even take off from demanding Leh hot & high climate with 1.9 ton load
Not many twin engine IAF fighters can take off with 50% load from Leh
Tejas Mk1 reaches the top of its vertical loop in 8 to 8 seconds routinely in air shows, did 8.5 G max till now, slow speed 110 knots, min turning radius under 350 meters
It's zoom climb just after taking off from runway in Bahrain sir show was breath taking
It has DRFM based AESA jammers for self protection, the ELTA 8222WB SPJ is slated to go on board as well
Tejas Mk1 Tejas Mk1A have conical chamber for better lift at all AOAs. Tejas_LCA benefited from Legendary aerodynamics scientist Valluri who set up NAL. He also initiated, studies on composite materials & fly by wire concepts in late 70s far ahead of times.
Over 90 % of TejasMk1 surface & 45 % of its airframe by weight is made of composite . This is highest usage of composites in aircraft of any kind, anywhere in the world. Leading to lowering of aircraft’s weight by 21% and reduced its part count by 40%
Longitudinally unstable Tejas Mk1 has enhanced maneuverability. Tejas_LCA's static margin, i.e. a measure of its instability (hence maneuverability). To recover stability & provide good handling qualities
Tejas Mk 1 & 1A is equipped with a fully redundant quadruplex digital fly-by-wire flight control system (FCS). This FCS is one of the biggest accomplishments of Tejas_LCA program. Its robustness has ensured an accident-free test record of over 4,300 test flights. Since then Tejas Mk1 has completed 10000 hours ( test flight & operational sorties for flying daggers & flying bullets squadron) without any emergency
It's a stupendous reliability parameter fof Tejas_LCA program, especially a green field one with no experience
Tejas Mk1 Tejas Mk1A ITR 30 degrees/sec and a sustained turn rate (STR) of between 15 to 16 degrees /sec second
