Narrative:

I was the pilot flying a transatlantic leg to jfk; I landed at jfk and the conditions were VFR with calm winds. I was cleared for a visual approach runway 22L. Between 2;000 and 1;000 AGL I was one dot below the glide slope; gear down; flaps 15 and on auto pilot. I received a [low altitude] alert from the tower so I disconnected the auto pilot and manually returned to intercept the glide slope; configured to flaps 30 degrees and landed on runway 22L.
