LPPT (Lisbon-Portugal) Radar Approach
Aircrafts are normally vectored to the ILS and "cleared ILS approach RWY XX" when the final interception vector is given.
However, when the aircraft is being vectored far away from the ILS IAF and is crossing the localizer, aircraft may be cleared to follow the localizer which does not mean the aircraft is cleared to descend to IAF altitude or to follow the glide if receiving.
After being cleared fot ILS approach pilots are requested to report established on the ILS (both LOC and GLI) to be transferred to the Tower.
