Ofc they have radar and it’s a vectored approach to intercept the final approach track. The deviation left is not so significant (an NPA it is) that radar had to worry...and the crew aborted well before their MDA(DDA)...its another matter that had they just remained on the final approach track till their minimums they would in all probability have landed...but maybe the haze drove them thru the windshield earlier than they should have and then spotted some part of Mumbai airfield to the left (most of the airfield complex of parking stands, taxiways and a cross runway are all to the left), and they initiated a slight left turn; only to abort soon after. My point is that JUHU runway is pretty insignificant and impossible to spot in such conditions, and in any case it was still to their left in this case...so what’s all this about.
