Descent
During descent, LNAV progress is managed using the RTE LEGS and
PROGRESS pages, as in the cruise phase. VNAV descent management is
accomplished primarily on the DES page.
The DES FORECASTS page is also available to enter forecast wind data to aid in
descent planning.
Descent Page (During Cruise)
The descent page is used to monitor, revise, or select the descent path. Descent
modes are economy (ECON) path and manual path and speed. The default VNAV
descent mode is ECON path. The crew must select a manual speed descent mode.
The page title reflects the type of VNAV path descent. The path mode controls
descent to fly a vertical path which complies with altitude and speed restrictions
in the flight plan.
