Flight Management, Navigation -FMC Cruise 737 Operations Manual

WIND
Used for entry and/or display of the true wind 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
(BANDR to ELN 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
(an entry of 080°/105 at BREEZR is depicted). The entry must be executed.
Any entries propagated from the CRZ WIND entry are displayed in small font.

Keyboard entries are displayed in large font.

Crew entries of forecast winds (or default 000°/000) are automatically biased with
the actual wind computed by the FMC when within 100 NM of a cruise waypoint
and within 2,000 feet of a cruise altitude. (U4 and on) Biased values are not
displayed.

Blank for non–cruise waypoints (PLUSS and MWH are depicted). Entry is
inhibited.

LEGS
Selection displays the RTE LEGS page.
Position Shift Page (U4 and on)
On the POS SHIFT page, each prompt indicates the bearing and distance of the indicated system relative to the FMC position. FMC position is displayed on line 1R of the POS REF page. The entries with parentheses in the center of the page show the active position references.
Data fields are blank when on the ground.
