I got one question: when you say "alternative procedure", do they talk about this in advance ? Or you have to just do an "alternative procedure" because of the vectoring?
The alternative procedure is described on the Jeppesen plate you get. As it is said, it is an alternative way of doing the approach and not the standard published on the chart. You have a small placard on the plate saying for example: Alternative procedure --> Fly heading 130° until you reach 7DME... then turn left to intercept localizer...
It is as simple as that
