LPV

An LPV approach is a GPS-based procedure that provides both lateral and vertical guidance down to decision height, much like a traditional ILS. LPV minimums are often as low as 200 ft decision height and a half-mile visibility. Unlike an ILS, LPV requires no ground-based transmitter at the destination, so it works at thousands of smaller airports.

Flying LPV approaches requires a WAAS GPS navigator. Non-WAAS units can only fly LNAV approaches, which have higher minimums and no vertical guidance. If earning an IFR rating is in your plans, practicing LPV approaches in training is well worth it.
