Hello,

2)If you use Jeppesen charts, since you have WIP rwy 35L in MXP, a yellow side step chart has been released by Italian CAA, 19-10 (I think..) with a published procedure and associated distances and minima.
As per JAR OPS, I cannot recall something specific for side step, but this is basically a visual manoeuver, I would say if you have good WX conditions, I would aim to be stabilized by 500 ft on the landing rwy.
So long
