FLIGHT MANAGEMENT
Disabling VNV guidance:

2) Select the CNCL VNV Softkey; or press the MENU Key, highlight ‘Cancel VNV’, and press the ENT Key. Vertical
navigation is disabled.

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 system allows a vertical navigation direct-to to any waypoint in the active flight plan with an altitude
constraint “designated” for vertical guidance. Selecting 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.
