arff,
2 eng or single engine, at max landing weight of 66.000kg and full flaps, the A320 will use about 900m landing distance from 50ft above the treshold to the stop on a dry runway. That is, if almost no flare is used and immediate full brakes - test pilot stuff.
A sort of "normal" landing distance would be in the region of 1500m with medium autobrakes.
At max landing weight a speed of 136 kts should be flown to touchdown, an additional 5 kts would increase the land dist by 8%, a 10 kts tailwind adds another 18%.
Thrust reverse on both engines would reduce the land dist by about 5% but is not required for performance calculation on dry runways.
If no reverse is used there should be absolutely no reason for hot brakes and the approach landing is quite similar to a 2 eng app and landing except for the higher thrust setting required and rudder trim. The autopilot/auto thrust system will handle single eng flight without problems.
