This advi-sory guidance follows the same nature asset by the LNAV +V as shown above.Published LP minimums.NOTE: Advisory vertical guidance information displayed on the VDI in this mode is only an aidto help flight crews comply with altitude restrictions. When using advisory vertical guidance,the flight crew must use the primary barometric altimeter to ensure compliance with all alti-tude restrictions in accordance with the LP or LNAV approach procedure.While Flying an RNAV ApproachAfter the aircraft has passed the FAF, a loss of WAAS integrity will cause the approach to be abortinstead of downgrade.Points to Remember for All Approaches• The GNS 480 is designed to complement your printed approach plates and vastly improve situ-ational awareness throughout the approach.
