Tejas at Colombo, only two-seater trainers apparently for the first time.

This better be a sales pitch... BECAUSE LOHA HAS NEVER BEEN THIS GARAM!

Sri Lanka Air Force has 7 IAI Kfir (only 1 operatinal in 2016 tho... half dozen of both Mig-27 & J-7 too, all non-operational) that they were trying to replace and/or upgrade in 2017.
The Sri Lankan government publicly announced in 2016 that it intends to issue a RFI in support of a programme to procure new fighter aircraft. Sri Lanka’s President, Maithripala Sirisena & his Cabinet on gave their formal approval for the solicitation of offers from foreign aircraft manufacturers for the procurement of a number of new aircraft and associated weapons through an inter-government agreement on 11 August 2016.

does it also help in identifying the threats earlier if adversary is already in the library?suppose j20 is now in the threat library of spectra so can rafale detect j20 at more range than it detected the first time
Yes !
Threat library contains all data of previous encounter such as RCS , IR signature , plume analysis , profile and flight envelope . So it might help fatser indentification even at greater distance.

usually people talk about updating the threat library and iaf even acquired the facility fram dassault to add their data of threats to spectra,
On one forum i read that a plane whose signature is stored in threat library can be detected even by a faint picture is painted on the radar ,i dont know it is correct or not , i think it means library is like cache memory that is program opens fast on a system if it is stored in cache already
Dude, a cache memory stores instruction sets and driver related modules that helps run a program faster. These are enablers rather than passive signatures.
Anyways towards your doubt: there are multiple radar signatures that cone from various sources via enemy. It may be of land based radar, SAM radar, fighter radar or seeker of a missile. Assuming we are talking about bankrupt porrks here with PESA tech, every airborne radar source has a particular signature. Again there is signal spectrum, pulse modulations, signal frequency, etc that further discriminate a fighter or seeker from the other.
So technically you have a lot of signals to process and within very less time. This is where integrated super computing stations installed on jets come to picture. An average AI can differentiate between a jet's signature and a missile seeker's signature(assuming there is no current signature in it's data bank). A modern AI can however discriminate between fighters and even predict what make and model of aircraft is out there. This kind of AI requires a hell lot of hardware and power to successfully run, hence these are deployed on AWACS.
Spectra and RBE2 are definitely a different breed than our regular BARS radar. Signals and signatures collected by them are continuously analysed in the background while Rafale detects the enemies in scan mode.
Once an enemy missile is fired, SPECTRA can generate mirror FCR signature of host jet to make missile go off course. This is something that even our best EW suite can't reproduce.
Now whether these signatures are kept in cache? Maybe... but the processing speed of jet's super computer make sure enemy's signature is stored well and retreived as soon as something flashes on the radar.

This must be a sure shot sales pitch, else there is no need for the trainers to be there. The Srilankan pilots are going to get their hands on on this beauty. Its said, the pilot machine interface of this aircraft is seducing enough for any pilot.

thanks for such a simple yet elaborated reply!

sir as u good know of how ew suites work


can u explain the meaning of the features of ew suite(spectra to be precise)


RWR/ESM
  • Digital receivers
  • 3 antennas with 120° azimuth coverage each located on the intakes and fin tip pod, plus additional antennas on the wing tips
  • Interferometry (azimuth & elevation) with stated <1 deg bearing accuracy
  • Target coordination generation for weapons employment
what is the 3rd point i.e interferometry one trying to say
is it a passive targeting method if yes how it works

One concern , don't you think if SL buy tejas , can provide access to china/pak. Will India have kill switch in that ?

Two seater variant for Srilankan pilots to be back seat driver during flight.

I am sure the export version would not be as potent as the one that flies in the Indian Airforce so we wouldn't really mind Pakistan or China having a closer look at it.

Coming to the Kill Switch. Having a kill switch poses more trouble than not having it at all. Imagine what happens when your enemy figures out how to activate the kill switch, your aircrafts would just fall out from skies.

Aren't all trainer versions like that? Anyone can take command of the aircraft, its not that the pilot behind would not have a flight control stick.

Yes. The variant would be trainer one. IAF is deliberately sending it for Sri Lankan pilots to take a flight on board.

But they may not get much of a feel in it, because those dont look to be FOC standard aircrafts. Maybe and only if they have upgraded its flight controls, sensors and avionics to FOC standards. Fingers crossed.
