SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS AUDIO PANEL & CNS FLIGHT MANAGEMENT AVOIDANCE Automatic Flight Control System Prior to descent path interception, the Selected Altitude must be set below the current aircraft altitude by at least 75 feet. For the flight director to transition from Altitude Hold to Vertical Path Tracking Mode, acknowledgment is required within 5 minutes of descent path interception by: • Pressing the VNV Key • Adjusting the Selected Altitude If acknowledgment is not received within 1 minute of descent path interception, the white 'VPTH' annunciation starts to flash. Flashing continues until acknowledged or the descent path is intercepted. If the descent is not confirmed by the time of interception, Vertical Path Tracking Mode remains armed and the descent is not captured. In conjunction with the "TOD [top of descent] within 1 minute" annunciation in the Navigation Status Box and the "Vertical track" voice message, VNAV indications (VNAV Target Altitude, vertical deviation, and vertical speed required) appear on the PFD in magenta (Figure 7-11). Selected Altitude VNAV Target Altitude Altitude Hold Mode Active Vertical Path Tracking Armed and flashing Vertical Deviation Indicator Required Vertical Speed Indicator FMS is Selected Navigation Source Terminal Phase of Flight Figure 7-11 Vertical Path Capture When a descent leg is captured (i.e., vertical deviation becomes valid), Vertical Path Tracking becomes active and tracks the descent profile (Figure 7-12). An altitude capture mode ('ALTS' or 'ALTV') is armed as appropriate. HAZARD AFCS ADDITIONAL FEATURES APPENDICES INDEX 190-01263-01 Rev. A Garmin G2000 Pilot's Guide for the Cessna T240 451
