Canceling vertical navigation results in vertical deviation (V DEV), vertical speed required (VS REQ), and time
to top of descent/bottom of descent (TIME TO TOD/BOD) going invalid. The Vertical Deviation Indicator (VDI)
and Required Vertical Speed Indication (RVSI) on the PFD are removed, and the V DEV, VS REQ, and TIME TO
TOD items displayed in the CURRENT VNV PROFILE box are dashed. VNV remains disabled until manually
enabled. Vertical guidance in reversionary mode can only be enabled for a direct-to waypoint.
The G950 allows a vertical navigation direct-to to any waypoint in the active flight plan with an altitude
constraint “designated” for vertical guidance. Pressing the
VNV Direct-to
Softkey on the Active Flight Plan Page
allows the flight plan to be flown, while vertical guidance based on the altitude constraint at the VNV direct-to
waypoint is provided. The altitude change begins immediately and is spread along the flight plan from current
position to the vertical direct-to waypoint, not just along the leg for the direct-to waypoint. A direct-to with
altitude constraint activated by pressing the
Direct-to
Key also provides vertical guidance, but would bypass
flight plan waypoints between the current position in the flight plan and the direct-to waypoint. A top of descent
(TOD) point is computed based on the default flight path angle; descent begins once the TOD is reached.
