"If while doing an ILS approach you lose the glide slope, you can REQUEST the Localizer approach. You may not get permission from approach in time so you must execute a go-around and set up for the Localizer approach"
Not true. If the LOC minima are on the ILS plate, the approach is still technically an "ILS" approach even if you don't use the GS. If there are no LOC minima on the plate you need to request a different approach or go-around.
