SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS Automatic Flight Control System NOTE: Some RNAV (FMS) approaches provide a vertical descent angle as an aid in flying a stabilized approach. These approaches are NOT considered Approaches with Vertical Guidance (APV). Approaches that are annunciated on the HSI as LNAV or LNAV+V are considered Nonprecision Approaches (NPA) and are flown to an MDA even though vertical glidepath (GP) information may be provided. WARNING: When flying an LNAV approach (with vertical descent angle) with the autopilot coupled, the aircraft will not level off at the MDA even if the MDA is set in the altitude preselect. Upon reaching the glidepath, the flight director transitions to Glidepath Mode and begins to capture and track the glidepath. Figure 7-15 Glidepath Mode Armed Once the following conditions have been met, the glidepath can be captured: • A GPS approach with vertical guidance (LPV, LNAV/VNAV, LNAV+V) is loaded into the active flight plan. • The active waypoint is at or after the final approach fix (FAF). • Vertical deviation is valid. • The CDI is at less than full scale deviation • Automatic sequencing of waypoints has not been suspended (no 'SUSP' annunciation on the HSI) FMS Approach Mode Active Glidepath Mode Active AUDIO PANEL & CNS FLIGHT MANAGEMENT AVOIDANCE HAZARD AFCS ADDITIONAL FEATURES APPENDICES INDEX FMS is Selected Navigation Source LNAV/VNAV Approach Active Command Bars Indicate Descent on Glidepath Figure 7-16 Glidepath Mode Glidepath Indicator 190-01263-01 Rev.
