Ok let's start from the scratch once again.
Visual approach: An approach when either part or all of an instrument approach procedure is not completed and the approach is executed with visual reference to the terrain.
In our case it'd be ILS 27 which would partly or completely completed by visual means. The mere fact of one flying visual with terrain doesn't waive ILS in use and flying under IFR bounds one to the published procedures unless RV. (radar vectored). Well those of us involved in training do shoot quite few MA and so far it was either published MA or RV.
I'm having a bit of trouble with the punctuation here "surely not neither does it cancel an IFR procedure"?
IOTW clearance to execute visual doesn't waive IAP in place for this RWY and IF rules are to be followed. ATCO guys would shed some light on it I'm sure about it.
Cheers
