NAS Implementation - Procedures - Localizer Performance with Vertical guidance (LPV)
Localizer Performance with Vertical guidance (LPV) approaches take advantage of the refined accuracy of Wide Area Augmentation System (WAAS) lateral and vertical guidance to provide an approach very similar to a Category I Instrument Landing System (ILS). Like an ILS, an LPV has vertical guidance and is flown to a Decision Altitude (DA).
Example: RNAV(GPS) Y RWY 17L at Will Rogers World Airport, Oklahoma City, Oklahoma (OKC)
Helicopter Point in Space (PinS) LPVs
Helicopter instrument flight is relatively new when compared to airplane instrument flight. Until recently, helicopter Point in Space (PinS) LPV approach procedures were only available as Special Instrument Flight Rules (IFR) approach procedures. Shown here is an example of Special IFR approach procedure.
On November 20, 2012, FAA Order 8260.42B - U.S. Standard for Helicopter RNAV, was updated to include new IFR Helicopter Departure and Localizer Precision with Vertical (HLPV) criteria. This document provides guidance for initiating and processing requests for public and special instrument and visual flight procedures including area navigation (RNAV) procedures.
Example: Copter RNAV (GPS) 265 at Harris Methodist Hospital in Fort Worth, Texas
