We are what we are today is because of a reason other than lack of brains or/and resources. Fortunately, seeds for change have been sown and we are progressing on right track. I leave it to that.

Anyway, its too far from Turbofan vs Turboprop debate. So, I am summing up.

We did not select A400 despite the fact that it could have been used as a multirole platform for cargo roles because it's a Turboprop which negatively affects ceiling performance thereby affecting effective radar range. A crucial point for a proper AWACS.

You are saying the most important factor is altitude, I am saying the most important factor is loiter time. The turbofans you mention loiter for extended periods, that is why they make good AEW.

Of course it can if your radar meets the payload restrictions.

Get the radar within one tonne and it should be fine.

Saras can be a good platform for SIGINT duties ..

Jai hind!

30 Character rule sucks

 

[proud_indian]

I congratulate CSIR-National Aerospace Lab scientists on the maiden flight of 14 seater SARAS PT1N. Designed & developed by CSIR-NAL, it flew for about 30 minutes this morning at a maximum height of 8500 ft at a speed of 145 knots. All the system parameters are found normal.

30 characters wtf, why mods why this shi**y rule
