The United States Standard for Area Navigation (RNAV)
|Publication Date:||7 December 2007|
Purpose of This Order.
This order specifies criteria for obstacle clearance evaluation of area navigation (RNAV) approach procedures; e.g., Localizer Performance with Vertical Guidance (LPV), Lateral Navigation (LNAV), Lateral Navigation/Vertical Navigation (LNAV/VNAV), and Localizer Performance (LP). These criteria support adding an instrument landing system (ILS) line of minimums to an RNAV (GPS) approach procedure using LPV construction criteria at runways served by instrument landing system. Apply feeder segment criteria (paragraph 2.7) to satisfy RNAV Standard Terminal Arrival Route (STAR) and Tango (T) Air Traffic Service (ATS) route obstacle clearance requirements.
Note: These criteria do not support very high frequency (VHF) omnidirectional range/distance measuring equipment (VOR/DME) RNAV, inertial navigation system (INS), or inertial reference unit (IRU) RNAV operations, or DME/DME RNAV final or missed approach operations.
