Here’s some information from the CSIO Annual Report (courtesy of ASharma on BR) that shows the indigenous HUD being used on the Tejas LCA and Sitara HJT-36

regarding the issue of fratricide being mentioned in the talk by Col. Fornhoff, Vishnu had this to say and it makes obvious sense since the Sukhois were operating as part of the “Blue” force with Rafales and F-15Ks as well as USAF fighters part of the “blue” force.

Location: New Delhi A quick couple of important points about fratricide incidents …

None of the fratricides saw Sukhois shooting down Sukhois. Any fratricide incidents committed by the Indian Air Force were because of the following reasons …

IAF Sukhois are not fitted with IFF Mode 4 which is the NATO standard. Hence they could not interrogate their contacts.
The radar IFF onboard the Sukhois is designed to interrogate Indian Air Force fighters … NATO standard jets obviously do not carry equipment which enables a Sukhoi 30 using its a Bars radar IFF system to interrogate them.

Thanks

A fault indication made the pilot to do a emergency landing. The circumstanses made the pilot to turn off the engine directly on the runway after a full stop. And the nose wheel just popped up(not broken) when the engine died. The causes is to be investigated.

thanks for the info. any link that explains in any greater detail?

BTW, Rahul, thanks for the cross-post from BR..lots of very illuminating points are mentioned there..the Sustained TR of 35 deg/sec or more for the Su-30MKI is one..I remember reading what one IAF pilot had written in an email to one BR poster, asking doubters who thought that the IAF Su-30MKI had been shot down to check the ACMI footage from Mountain Home AFB to verify that they had not been shot down at all..

is there someone here who can verify that with the Mountain Home authorities?

any info on what happened to cause the Gripen emergency landing with its nose wheel broken off?

HAL was founded in 1964 according to them self… And what i was talking about is the designing of an own fighter jet…
I know they have done many good things in the past, like the MKI, that is really good peace of engineering.
But with all respect, that´s not designing your own jet, with all the underlying komponents, like avionics and sensors, frame, aero etc. That is what BOIENG, Dassault and SAAB has done in 60 years. So i hope they manage the big step, thats all.

HAL built the HF-24 Marut, which did enter IAF squadron service, but died out due to a poor engine, the replacement for which, never came on time..and after that, IAF was satisfied simply importing cheap Russian fighters that were provided at “Friendship” prices..that effectively ended up killing a follow-up HF-73 strike fighter that HAL had done extensive wind-tunnel testing on..its pic should be available if you look it up.

Col. A Shukla is indeed a very good source of information when it comes to Tejas and other Indian weapon systems. But this article gives rise to some question, and maybe some informed member can shed some light on these.

1. Removal of telemetry equipment would indeed reduce the weight, but do these Tejas (with telemtry equipment) already carry everything else that is meant to go into production variant, i.e. radar, all avionics/subsystems etc?

2. By every standard Tejas is a relatively a modern fighter considered to be at least on par with early Gripen/F-16s by even those who might not like it. I have only seen pictures of its cockpit which looks quite modern. So which particular displays and subsystems ‘within the cockpit’ could be re-engineered to save 300 kg? And how much do these displays and subsystems weigh to start with in any case?

Regarding Teja’s ability to carry fuel/weapons equal to Mig-29, Mig-27 etc, please see the very same article quoted by yourself, and Col A. Shukla’s remarks about Tejas MTOW.
PS. I do realise that this article was written a little while so things might have changed of which Im not aware of.

Vikas, it is a lot more modern than early F-16s..those weren’t even BVR capable and had a late 70s/ early 80s avionics fit and radar.

at least the initial couple squadrons of Tejas will end up with a very capable hybrid MMR that retains the hardware of the MMR, the TWT, antenna, and receiver/exciter but with Elta signal processing units, which are needed especially for the A2G modes. India sends them all the systems, they integrate and test it with their units. Next MMR will probably be a AESA and work is already progressing on that front (you can read what LRDE’s boss Vardarajan said in an interview about them developing an AESA in a post somewhere above)..they will definitely use the MRCA’s winner to extract help on this, so the radar is going to be one of the best in the IAF fleet.

MMR will be a pretty decent thing if it comes out as needed, i.e. 100 km plus range against a 2 sq mtr target, and this is from a very good source. add to that internal SPJ, an in-development IRST and all in all the Tejas Mk.2 is almost on par with what the Gripen NG will be..obviously the Gripen has the advantage of years of service and operational use, but capability-wise, the Tejas will be almost on par- it needed the blessing and support of the IAF and thankfully that is there now

As for weapons, it’ll be carrying whatever is the best A2A weapon in the IAF inventory, and its already mated with the Litening LDP, so carrying LGBs should be possible by the time it reaches IOC itself.
