RNAV FINAL APPROACH DESIGN CRITERIA

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 approaches.
• VOR/DME based RNAV approaches.
• Stand-alone RNAV (GPS) approaches.
• RNAV (GPS) approaches with vertical guidance (APV).
• RNAV (GPS) precision approaches (WAAS and LAAS).
