Only if the aircraft is limited to CAT I. Where does it say it is?
what I mean is that when you fly a Cat 1 ILS, your minima can never be less than 200' - it is a procedure limitation not an aircraft one.
You can only fly Cat II ILS at airports with the appropriate ground lighting and equipment.
Many helicopters are physically capable of flying lower than Cat I limits - it depends on the AP fit but to legally fly Cat II I think you would have to jump through a number of regulatory hoops.
I get the impression you want to fly CAT II ILS using an i-pad or similar, is that the case?
