No-one's answered yr question re Localiser Approaches.
It's simply that with an ILS, you get an instrument display of the approach profile in two dimensions, Horizontal = LOCALISER; Vertical = GLIDESLOPE.
If a GLIDESLOPE (G/S) is not provided (as Sumburgh 09) or if it fails (e.g. HC's Aberdeen example) the approach is flown by following the LOCALISER, but descending according to tabulated guidance about what altitude you should be at for your distance out. So it's called a LOCALISER approach
For your purposes, will this do? I'm assuming you want to understand the general idea, not the technicalities.
