RNAV encompasses a variety of underlying navigation
systems and, therefore, approach criteria. This results
in different sets of criteria for the final approach segment
of various RNAV approaches. RNAV instrument
approach criteria address the following procedures:
GPS overlay of pre-existing nonprecision
VOR/DME based RNAV approaches.
Stand-alone RNAV (GPS) approaches.
RNAV (GPS) approaches with vertical guidance
RNAV (GPS) precision approaches (WAAS and
