Hmmm...yellow-tinted piece of glass. Apertures for MAWS, I presume?
@Dillinger @Abingdonboy @kurup Need your opinion.

MMRCA is getting delayed beyond its boundary. Soon it will be useless and costly to block 20bil in it.
Better we focus on PAK FA and LCA MK2. The 20bil will add more value in it.

Looks like you are right buddy .

On the fuselage sides of the t-50-4, just aft of the cockpit, two sensors are mounted to serve the 101Ks-U ultra-violet missile approach warning system (MaWs) together with two further 101Ks-U sensors fitted previously (on the third example) under the nose and atop the tail boom, the system provides observation of airspace all around the aircraft.

Antony to take up issues related to FGFA project with Russia - The New Indian Express

Not happy with its share of work in the multi-billion dollar Fifth Generation Fighter Aircraft (FGFA) project with Russia, India is expected to flag the issue with that country during Defence Minister A K Antony's visit there next month.

Though India is investing 50 per cent of the cost of the multi-billion dollar programme, its work share in the research and development and other aspects of the programme at the moment is only around 15 per cent, IAF officials said here.

The Defence Minister is expected to flag this issue during his Russia visit beginning November 15 as this will have an impact on India's indigenous capabilities to develop such an advanced fighter aircraft, they said.

The IAF expressed its objection over the issue at a CII event on energising aerospace sector in India.

"We have a major opportunity in the FGFA programme. At the moment it is not very much in favour of Indian development. We are flagging it through the Government. It should be much more focused towards indigenous development capability," IAF Deputy Chief Air Marshal S Sukumar said here.

The senior IAF officer was commenting on the programme and the opportunities that it could provide for the Indian defence sector.

The FGFA is a joint venture programme between India and Russia and its preliminary design phase was completed recently.

The programme is expected to cost over 1.5 lakh crore to the Government. The two sides are now in discussion over the main Research and Development part of the programme, which

Looks it will block the AESA's downward waves ---- but I think it will not.

I am sure the designers of PAK-FA have took that into consideration before placing it there .

AESA waves are electronically steered. The radar lobe does not need to look down in order to see down.

The waves can be steered in the desired direction even after exiting the lobe, no worry.

Any metal parts sized bigger than half of the wave length will block (redirect/absorb) it.

That's why we have no pitot to tip the radome on a AESA equipped aircraft.

Scanning range of T-50 radar can be calculated easily base on this.

You also need to measure the power being output. Even this changes when the radar uses compression,
where it increases it's scan rate and scan range in a particular sector by paying less attention to
targets which have already been seen & marked by the computer, leaving more power to search for new,
smaller RCS targets.

Thanks for reply.

Will it create blind-spot below the front where great chance the A2A missile come from?

Or the "blind spot" were monitored by the said MaWs there?

No. The waves are steered clear. Additionally, it has 2 additional AESA radars
in the sides which can see those targets that are out of view of the front AESA.

The system includes sensors to the front and the back under the cockpit and the tailsting:
