"ACMS"
Many times when you are flying a Visual approach, there is a reason for this, generally it is that the ILS is unserviceable.
If the the ILS not working, or you are told to NOT use this NavAid, and make a visual approach, you would most certainly NOT tune in the ILS for any kind of reference, as it would be unreliable.
This is BASIC stuff.
And for "ratpackgreenslug" - The Airbus have NO MAGENTA LINE.
There are certain tools that could have been used, example extended centre line and various fixes, to establish current position for the approach to assist with SA.
