RCS reduction is not just whats in the F-22 alone. The YF-23 black widow had other stealth concepts incorporated which are being used on UCAVs.F-22 is a beast in the sky.
When we are talking about the stealth, its not an invisible one, but AMCA is needed for the first wave of the IAF to breach the enemy lines, in high, multi threat environment, when most of the enemy defensive, and surveillance equipments are intact.
1. RCS reduction - The shaping of AMCA looks promising, plus the serpentine airintake duct adds to stealth. For the skin, I think ADA will again go for the composites, and NAL have to come up with exclusive composite for the stealth material. Tin Irridium Oxide Compound aka Ram coating, have been developed by the DRDO long ago, but how much is it effective, have to be seen. In F-22 its the special skin that covers its surface, which need constant and quick replacement and maintainance. From Russia, we heard some news of experiment of the Plasma stealth.
2. Heat Reduction -- The shape of AMCA is fine, and the tail hides some of the engine heat, but not like the US F-22 which has flat engine outlet, and the engine is completely hidden from sides. If I consider F-414IN EPE X 2 engine used in AMCA, then question arises, whether ADA goes for TVC or not. I think India should start Kaveri-2 with 120 Ktn target.
3. EW - Now this is the field which is very important. DRDO/DARE can designed EW suites, comprises of AESA MMR, Maws, RWR, LWR, IRST, OLS, iFF,Internal Jammer, Targeting Pod, Secured link, and Radio. taking various components off the self. HAL have experience in the mission computer with the HAL/Edgewood Mission and display computer in MKI and LCA, and could work for more powerful computer for the data fussion, and better situation awareness.
Brother @@Abingdonboy@@PARIKRAMA@@dadeechi@@AMCA@@nForce For me 5th Gen fighter plane is not just a plane, but its a system, and a plane is just small component of that system. In that system, all the components works together in the coordinated, and comunicationg to each other. IT include not only a plane, satellite, smart weapons, and all the sensors, which aided with the computing power actually gives Pilot the broad view image of the whole battlefield, and the load of options to choose the best one for achieving the target of the Mission.

As far as engine housing and heat reduction, the solution may arrive from the T-50/Pak-fa. What they some up with may be possible to have on the AMCA. Reduces the RnD and there for final product cost.
EW should be dealt with multi vendors. HALs job is to integrate it. Rafales spectrum EW suite may not be limited to just the Rafale.
