Hi Cala
Forgive me for writing this in English, my Italian is not so good.
A cloudbreak procedure is used when the operational runway is not served by a precision approach procedure, often because of the impossibility of an ILS installation due to terrain considerations. So, a precision approach is flown down to a point where the runway can be seen and a visual circuit flown.
The ILS procedure will be flown down to circling minimum, with all checks complete apart from land flap. The circling minimum is stated on the approach plate as a minimum circling height and met. visibility for the speed category of the aircraft.
On reaching circling minimum, if the landing runway is in sight and can be maintained visually to touchdown, the cloudbreak can be followed.
It will usually be along the reciprocal runway ILS, and on reaching circling minimum, turning 45° for a timed period to intercept the downwind leg, followed by a normal visual landing.
The thing to be aware of is that in the event of a missed approach if terrain is a consideration, the missed approach procedure for the early part of the approach will be that for the ILS and for the latter part, that for the landing runway. If you have to break off at some intermediate point, due to loss of visual reference, make sure to turn the right way.
