Localizer Performance with Vertical Guidance (LPV) enables flight crews to fly an approach similar to the ILS CAT 1 minima, with the benefit of not requiring ground-based landing aids. Instead, the LPV approach utilizes a Space-Based Augmentation System (SBAS).
Such a system is available in several high traffic regions of the world, including WAAS (U.S.) and EGNOS (Europe). As of December 2020, all instrument runways ending with a non-precision approach (NPA) within Europe must have an approach based on LNAV/VNAV or LPV.
