6. 277a_W00OCT03_CM New RNAV Approach Plate  Approach and landing operations with vertical guidance (APV) - An instrument approach and landing which utilizes lateral and vertical guidance but does not meet the requirements established for precision approach and landing operations.  LPV - a new line of minima using the Wide Area Augmentation System (WAAS). This approach combines the lateral precision of a localizer with the vertical performance of APV-1. Provides significant operational benefits as compared to LNAV/VNAV approaches.  LNAV/VNAV - A vertically guided approach with a decision altitude down to 350 feet above the runway touchdown point (HAT). Requires a WAAS-certified receiver (or certain Flight Management Systems with barometric VNAV). Visibility requirements are generally one mile at airports without approach lighting systems.  LNAV - A nonprecision approach (no vertical guidance) with a minimum descent altitude (MDA) of 250 feet above obstacles along the flight path. At many airports, LNAV approaches will have lower minimums than existing VOR or NDB approaches. LNAV approaches can be conducted today with approach-certified (TSO-129) GPS receivers.
