Early Descent
Early descents are initiated from the DES page. Once an early descent is executed, VNAV transitions to the descent mode and cruise features are no longer available.
For a path descent the DES NOW prompt will not be displayed until a descent path is established. Once executed, the autothrottle adjusts thrust to maintain 1000 feet per minute until intercepting the descent path.
For a speed descent, the autothrottle retards to idle and pitch maintains target speed.
Descend Now (DES NOW)
Selecting the PATH DES page before reaching the top of descent displays the normal descent page with the prompt DES NOW on the bottom right of the page. Selecting and executing the DES NOW prompt initiates a VNAV descent of 1000 feet per minute at ECON speed. Upon reaching the planned descent path, VNAV transitions to maintain the planned descent path.
Selecting the SPD DES page and executing the DES NOW prompt initiates a VNAV descent at idle thrust and target speed.

Waypoint
Displays the identifier for the waypoint from the ACT RTE LEGS page.
WIND
Used for entry and/or display of the true winds at the cruise waypoint identified
on the same line.
Entry may be via the keyboard, or propagated from the CRZ WIND entry on the
PERF INIT page.
The CRZ WIND value (075°/45 is depicted) propagates to all cruise waypoints
(ABC to GHI is the depicted cruise segment).
If no CRZ WIND entry was made, the FMC assumes 000°/000.
A keyboard entry has priority and propagates to all down path cruise waypoints 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：737NG机组操作手册Flight Crew Operations Manual FCOM 3(116)
