reaching with in range of 200-240 k.m. is impossible for jf17
Reaching 200-240 km from the target won't do any good what so ever.Because from 240 km range,in all probability JF 17 will not be able to detect the carrier.
At 180-200 km,it would detect the target but won't get a missile lock.
So in order to get a missile lock,he has to come 130-150 km from the Carrier,which will in all probability become next to suiside for the pilot.
That's why I always say that first read the piece well,then digest it,then absorb it and only after that pass on your thoughts.In real world it doesn't work well the other way round.
